Concrete pumping has become one of the most widely used approaches to place concrete. With the increasing use of pumping to place concrete, the development and refinement of the practice to ensure successful concrete pumping is becoming an important need for the concrete construction industry. Pumping enables the transport of concrete to forms and molds while increasing the speed of delivery and allowing access to hard-to-reach areas. Concrete pumps are likely to vary according to the end-use industry and quality of the concrete required for construction activities. Consequently, the optimization and development of prediction methods for concrete pumping is becoming a crucial issue for the concrete industry.
types used across projects
Stationary Concrete Pump
The stationary concrete pump is small, light and features a powerful dual-piston pump. It is used for manual, not synchronised additives adding shotcrete and fine concrete. The high diameter cylinder ensures the specified maximum output in the lowest possible strokes per minute, thereby reducing the wear & tear of the pumping system substantially. This pump has a smaller towing length for better manoeuvrability in narrow areas. Equipped with latest S-valve technology (only one side wear and tear) and with highly wear resistant steel components. It has 50–80% more life and reduced towing length for better use in narrow areas. Electro hydraulic control elements are designed and installed for easy access and replacement when necessary to change the parts. Also all the electrical parts aree- asily accessible by opening the control panel lids. Users continue their work quickly on simple faults by changing the necessary part easier rather than changing the integrated unit.
Trailer Mounted Concrete Pump
These pumps for almost any application, from pressure grouting and shotcreting to placing cement-based overlays and structural concrete. It is used for manual, not synchronised additive adding shotcrete and fine concrete up to a grain size of 16 mm. With a delivery pressure of up to 68 bar and an output of 18 m³/h, it is a real power pump, despite its small dimensions and low weight. The latest models comes mounted on a single axle or multi-axle trailer and high pressure is used to pump the concrete. These trailers are transported to construction sites by attaching them to a suitable vehicle. These are also called stationary or line or static concrete pumps.
Truck Mounted Boom Concrete Pump
Latest boom pumps feature the robust yet lightweight EZ Clean which is engineered for performance and durability. For added safety, the hopper incorporates an RFID safety switch, preventing it from operating with the grate open and incorporating zero moving parts. There are optional features like pump kits, Concrete stop valves and Automatic lighting systems. With the deck-mounted side pipe rack and large fold-up side panels now standard, these pumps allow for plenty of space and provide a quick, convenient and clean way to store everything that’s required for your project. The latest models use Ergonomic Pump System (EPS), which optimises the pump and other functions. Integral to EPS, Ergonomic Output Control (EOC) reduces fuel consumption, wear and noise, adjusting the engine speed to the delivery rate. They are set up easily in low overhead clearance conditions. These are used for large projects especially where you need to place concrete in hard-to-reach locations.
Truck Mounted Boom Static Pump
Modern truck-mounted static pumps are equipped with a carrying capacity of the 100-meter delivery pipeline, an integrated water tank for high-pressure cleaning and a provision for air compressor and pressurised air tank for cleaning of the pipelines These pumps are also much smaller and more compact than their boom pump counterparts, making them much easier to transport and maneuver around a job site. They are also equipped with a water tank and a flushing water pump. Because of its flexibility and lower-volume capacity, you will more commonly use a concrete line pump for pouring concrete on smaller residential jobs, like building a swimming pool or repaving a driveway.
Truck Mixer Concrete Pump
The robust design and the completely hydraulic mechanical drive of the truck mixer concrete pump guarantee a low – maintenance operation. It can also be equipped and tailored to the individual needs of our customers, with the chassis of your choice and the pump size and mixing drum capacity. It is used in places where truck-mounted concrete pumps are too big and inflexible. It is the ideal equipment for interior refurbishing work. The torsion-resistant, integral frame reduces wear, cuts costs, and ensures stability, especially during the pumping operation. The different configurations of the booms on truck mixer pumps ensure the greatest operative versatility and enable it to reach almost any part of the construction yard, even those accessible with the most difficulty.

Modern road construction projects rely on heavy-duty machinery. Here are just a few common work vehicles you can expect to see on the job site:
Dump trucks
Excavators
Rollers
Pavers
Forklifts
The ground has to be cleared to make way for a smooth, deep foundation. This foundation will hold the asphalt top that the rollers and pavers smooth out to create the road surface you’re used to driving on.
Safety Gear
While machinery handles the bulk of the lifting work, construction crew members must use a variety of shovels, stampers, pavers and other hand tools to assist the construction vehicles in creating a flawless road. Safety gear is essential for this line of work, so expect to see high-visibility vests, hard hats and safety glasses at minimum.
Measuring Devices
No roadwork project can be completed without a detailed plan and accurate measuring devices. This is where engineers help to create a dependable road construction. State-of-the-art engineering equipment is used to calculate the necessary foundation, measure the construction site and ensure the proper width, level surface and other features of the new road.

What Is an Excavator? Different Types and How They're Used |
Posted by: concretemixer - 09-06-2022, 07:10 AM - Forum: Excavation machinery
- Replies (1)

Also referred to as diggers, excavators are heavy construction machineries used for excavating earth and rocks and loading them onto dump trucks.
Excavators have a boom, bucket and cab on a rotating platform above an undercarriage with wheels or tracks. They can handle a wide range of works by changing the front attachment, which makes them a popular type of heavy equipment for construction.
What are excavators used for? Excavators are applied to a variety of contractor and industrial needs, including mining, road construction, building construction and demolitions.
There are many types of excavators — smaller machines handle digging and drilling functions, while larger excavators have different tools for heavy-duty projects. When renting your excavator, you’ll want to consider its size and speed as well as working conditions on the job site, such as the amount of space and the soil types.
The most common excavator types are crawler, dragline, suction, skid steer and long reach excavators. We’ll go over each type of excavator and the work each one is best used for.
1. Crawler Excavators
Key Feature: tank-like chassis with a chain track system Uses: mining, trench digging, landscape grading
Unlike other large excavators that run on wheels, crawlers run on two large endless tracks and are optimal for mining and heavy-duty construction jobs. Also known as compact excavators, these excavators use hydraulic power mechanisms to lift heavy debris and soil.
Their chain wheel system allows them to slide down and scale hills with less risk, making them suitable for grading hilly areas and landscaping uneven terrain. While slower than other excavators, crawlers provide greater balance, flexibility and stability overall.
Pros: Provide greater balance and stability on uneven ground
Cons: Slower than some other excavators
2. Wheeled Excavators
Keay Feature: wheels with optional outriggers for stability; Uses: roadwork and urban excavation projects
Wheeled excavators are similar in size and appearance to crawlers but run on wheels instead of tracks. Replacing tracks with wheels makes them faster and easier to maneuver on concrete, asphalt and other flat surfaces while still offering the same power capabilities.
Because wheels offer less stability on uneven ground than tracks, wheeled excavators are commonly used for roadwork and urban projects. However, operators can add outriggers to increase stability when transitioning between asphalt or concrete and an uneven surface.
Pros: Fast and easy to maneuver on flat surfaces
Cons: Perform poorly on uneven terrain
3. Dragline Excavators
Key Feature: unique hoist rope and dragline system Uses: underwater options, road excavations, pile driving
The dragline excavator is a larger excavator that operates with a different process. The equipment utilizes a hoist rope system that attaches to a bucket via a hoist coupler. The other side of the bucket is affixed to a dragline that runs from the bucket to the cab. The hoist rope raises and lowers the bucket while the dragline pulls the bucket toward the driver.
Due to their weight, draglines are often assembled on-site. The unique system of this type of excavator is commonly used in large-scale civil engineering projects like canal dreading.
Pros: Dragline system is ideal for underwater excavating and canal dreading
Cons: Weight and size make it impractical for smaller jobs
4. Suction Excavators
Key Feature: wheeled vehicle with high-pressure vacuum and water jets; Uses: underground applications, delicate digging projects, debris cleanup
Also known as vacuum excavators, suction excavators feature a suction pipe capable of providing up to 400 horsepower. The excavator first releases a water jet to loosen the ground.
The pipe, which contains sharp teeth at the edge, then creates a vacuum that carries away soil and debris up to 200 miles per hour.
A suction excavator is ideal for delicate underground applications, as it can reduce the chance of damage by more than 50 percent.
Pros: Added precision reduces damage during delicate jobs
Cons: Narrow suction pipes are impractical for large-scale applications
5. Skid Steer Excavators
Key Feature: wheeled vehicle with booms and buskets oriented away from the driver; Uses: residential projects, removing spread out or piled up debris
Unlike standard excavators, skid steers have booms and buckets that face away from the driver. This orientation allows the attachments to reach over the cab instead of around it, making these excavators useful in more narrow areas and maneuvering tricky turns.
They are often used for digging pools, site cleaning, residential work and debris removal, where space is more limited and objects are spread far apart.
Pros: Easy to maneuver in tight and narrow spaces
Cons: Don’t perform as well on uneven or slippery surfaces
6. Long Reach Excavators
Key Feature: 40-to-100-foot extendable arm with attachments; Uses: industrial demolitions, heavy-duty digging projects
As its name suggests, a long reach excavator features a lengthier arm and boom sections. The design allows for better operation in hard-to-reach locations. The excavator’s extendable arm can reach over 100 feet horizontally.
These excavators are best used for demolition projects like structural crumbling and breaking down walls over bodies of water. Different attachments can be affixed to the arm to perform additional jobs such as shearing, crushing and cutting.
Pros: Longer boom is ideal for hard-to-reach locations and demolition projects
Cons: Difficult to use in tight spaces
7. Mini Excavators
Key Feature: compact form with zero tail-swing capability; Uses: delicate terrian and narrow job sites containing obstacles
In recent years, more contractors are using mini excavators, a smaller and lighter version of the standard excavator capable of minimizing ground damage and fitting through crowded, narrow sites like parking lots and indoor spaces. Also known as compact excavators, mini excavators typically incorporate reduced tail-swing or zero tail-swing to maneuver tighter turns and avoid contact with any obstacles.
Pros: Easily fits into tight spaces and can be used indoors
Cons: Can only handle smaller loads
Excavator Attachments and Parts
Busket, arm, hydraulic cylinder, boom, cab, engine, counterweight, track frame
An excavator’s design allows it to serve many versatile purposes. Hydraulic cylinders, booms, arms and attachments provide digging and holding functionalities, while a house-like cab provides the driver with controls to direct the excavator. A rotating platform and wheels provide the necessary mobility to lift and remove debris from the worksite.
Excavators use a variety of hydraulic attachments that serve different purposes. In addition to a bucket, other common attachments include an auger, breaker, clamp and quick coupler.
bucket, auger, breaker, clamp, coupler
Bucket
Buckets are the most common attachments seen on excavators. These steel attachments have teeth-like edges that can provide digging and scooping capabilities. Buckets come in different varieties, the most common being ditching buckets designed for grading stones and trenching buckets used to dig trenches.
Auger
Attaching an auger allows you to bore into the ground. Powered by hydraulic circuits, these helical attachments can reach over objects and drill deep holes. Augers come in different specifications and sizes for various digging conditions and terrains — they range from 4 inches to 50 inches in length and can dig up to 32 feet.
Breaker
Breakers are similar to jackhammers but are much larger in size. With the ability to provide up to 1,000 pounds of impact energy, these attachments can break into tougher surfaces like stone and concrete.
Clamp
Clamps allow excavator operators to pick up large materials that are too oversized for a bucket, such as tree stumps and concrete. The attachments can be used with buckets or as pieces in a grapple. Clamps are easy to attach and detach from excavators.
Coupler
Couplers allow you to quickly switch between tools and attachments without a crew. Their versatility is handy when moving between different tasks and processes on a job site.
Differences Between an Excavator and a Digger
Excavator: can rotate a full 360 degrees, used for industrial and heavy-duty work; Digger: can rotate right and left 200 degrees, used for light to medium-duty work
Backhoes, also known as diggers, are a common fixture on construction sites but are often confused with excavators. While they share similar digging and lifting capabilities, backhoes and excavators differ in size, weight and functionality.
Excavators are generally large equipment weighing up to 200,000 pounds. Their bucket and boom design allow them to rotate a full 360 degrees.
A backhoe, on the other hand, is generally much smaller and shares more similarities in appearance with a tractor. The design means a backhoe can only rotate 200 degrees from side to side. Its front and back buckets can excavate materials, load waste and drag debris toward the vehicle. Renting a backhoe is best for light or medium-duty jobs with versatile applications.
While there are many different types of excavators, their core functionalities are similar. The lifting and digging abilities make them a staple on just about any construction site. Their high cost makes renting the most cost-effective option for most companies.

The stationary concrete plant is designed for produce high-quality concrete. It has the advantages of large output, high efficiency, high stability and high specification. Stationary concrete batching plants are reliable and flexible, easy to maintain and have a low failure rate. They are widely used in various projects such as roads and bridges, ports, tunnels, dams and buildings.
Stationary concrete batching has seen an upsurging rise in demand and manufacturers are modifying new models based on the customer need. The new models are furnished mainly with twin shaft mixers for maximised capacity, the plants are also available with Planetary mixers and batch sizes could be modified. The Stationary Plants are available in various capacities ranging from 30 m3 to 240 m3 per hour of compacted concrete output. In the current Stationary concrete plants, the aggregates are stored in horizontal bins. The gathering conveyor belt runs below the bins where the weighing of aggregates takes place and the aggregates are then discharged onto the charging conveyor. Pneumatically operated gates are provided for discharge of the aggregate on to the gathering conveyor. The material is all weighed accurately and transferred to the twin shaft mixer through a slinger conveyor. The new batching plants also come with the Skip Hoist and Belt arrangement option for mixer loading and a modular PLC-based control system with real-time SCADA for control and data management, The news design models can adopt Ice dosing, Microsilica dosing and some special additives very easily. An Admixture Dosing Unit and a standard Cement Screw Conveyor are also a part of the standard offering. Special plant designs are available for dam construction and precast manufacturers.
Stationary Concrete Plant generally consists of the following units:
1. Aggregate Bunker (unit where aggregate is stored)
2. Aggregate Weighing Conveyor (Unit where the aggregate weighed precisely weighed under the aggregate bunker)
3. Aggregate Transfer Conveyor or Aggregate Transfer Bucket (Unit that carries the weighed aggregate to the mixer)
4. Cement Silo (unit where cement is stored)
5. Cement Screw (unit that carries the cement from the cement silo to the cement scale)
6. Cement -Water-Additive Scales (units where cement, water and additive are weighed)
7. Mixer (a mixer in which the weighed materials are mixed homogeneously and quickly)
8. Main Chassis (The unit containing the mixer, cement-water-additive scales, has carrier legs under which a transmixer will enter.)
9. Control Cabinet and Computerized Fully Automatic Control System (Concrete is produced automatically according to the concrete recipes entered the system)
10. Air Compressor and Pneumatic Equipment (Produces compressed air required for the operation of the facility)
