What is a crawler hydraulic concrete placing boom?
A crawler hydraulic concrete placing boom is a self-propelled concrete distribution machine. It is used together with a trailer concrete pump, stationary concrete pump or concrete line pump to deliver concrete to the required pouring location.
The crawler undercarriage allows the placing boom to move between suitable working positions on the jobsite. The hydraulic boom can rotate and unfold to cover a large concrete pouring area, helping reduce manual pipeline handling and improve concrete placing efficiency.
HAMAC crawler hydraulic concrete placing boom is available in 20 m and 23 m working-height classes. It is suitable for large foundations, industrial buildings, tunnels, bridges, water projects, underground structures and precast concrete yards.
The main components of crawler hydraulic concrete placing boom
For a complete crawler hydraulic concrete placing boom, it contains the following main parts:
1. Crawler undercarriage, it is the traveling system of the crawler concrete placing boom. The crawler tracks allow the machine to move between suitable concrete pouring areas on the construction site.
2. Hydraulic placing boom, it is normally designed with four boom sections. The hydraulic cylinders control the opening, folding and movement of the boom sections to distribute concrete over a wide working area.
3. Slewing mechanism, it allows the upper structure and placing boom to rotate. The 360° slewing function helps the machine cover different concrete pouring positions from one working location.
4. Concrete delivery pipeline, it transfers the concrete from the trailer concrete pump or stationary concrete pump to the placing boom. The pipeline is installed along the boom sections and connected with a flexible end hose.
5. Flexible end hose, it is installed at the end of the placing boom. The operator can use the end hose to place concrete accurately into foundations, slabs, walls, columns, formwork and other concrete structures.
6. Hydraulic power system, it provides hydraulic power for boom unfolding, boom folding, slewing, crawler travel and stabilizer operation. The machine can be equipped with a diesel engine power system according to the final configuration.
7. Stabilizer support system, it is used to improve the stability of the crawler placing boom during concrete placing operation. The machine should be placed on suitable ground and stabilized before operating the boom.
8. Electrical control system, it controls the crawler travel system, hydraulic system, boom movements, emergency stop function and other operating functions.
9. Manual and wireless remote control system, the operator can control the placing boom through the control panel or optional wireless remote controller. The remote controller helps the operator stay close to the concrete pouring area and observe the placing process clearly.
10. Safety protection system, it may include emergency stop buttons, boom movement limit protection, hydraulic safety valves, warning labels and other safety devices according to the final machine configuration.
How does crawler hydraulic concrete placing boom work?
In order to explain clearly how the crawler hydraulic concrete placing boom works, we prepare the following working process:
1. The ready mix concrete is supplied from a concrete batching plant or concrete mixer truck to a trailer concrete pump or stationary concrete pump.
2. The concrete pump transfers the concrete through delivery pipelines to the crawler hydraulic concrete placing boom.
3. The crawler placing boom moves to a suitable working position according to the concrete pouring area and site conditions.
4. The stabilizers are deployed and the hydraulic boom is unfolded before concrete placing operation.
5. The hydraulic boom rotates and moves the flexible end hose to the required concrete pouring location.
6. The concrete is discharged from the end hose into the foundation, slab, wall, column, formwork or other concrete structure.
7. After finishing one concrete pouring area, the crawler placing boom can be folded and moved to the next suitable pouring position.
HAMAC HCB20-4 VS HCB23-4 crawler concrete placing boom
HAMAC provides crawler hydraulic concrete placing boom in different working-height configurations. The HCB20-4 is designed for projects that need a compact and flexible concrete placing solution, while the HCB23-4 is suitable for projects that require a larger concrete placing range.
When customers choose a crawler concrete placing boom, the required placing height, horizontal working radius, concrete pump output, delivery pipeline length, jobsite ground condition and transportation requirement should be considered.
The HCB20-4 crawler concrete placing boom is suitable for building foundations, basement projects, workshops, warehouses, tunnels and municipal construction projects. It is a practical solution for customers who need approximately 20 m class concrete placing coverage.
The HCB23-4 crawler concrete placing boom is suitable for large foundations, bridge construction, tunnel projects, water conservancy projects, industrial construction and precast concrete yards. It provides a larger working range for concrete placing projects that need wider coverage.
The final machine model should be selected according to the actual project requirement. HAMAC can recommend a suitable crawler placing boom and matched trailer concrete pump or stationary concrete pump for your project.
Where can crawler concrete placing boom be used?
Crawler hydraulic concrete placing boom is widely used in different concrete construction projects. It is especially suitable for projects where the concrete pouring position changes frequently, the working area is large, or truck-mounted concrete pumps cannot easily access the jobsite.
1. Large foundation and basement projects, such as raft foundations, pile caps, footings, underground slabs, retaining walls and equipment foundations.
2. Industrial building and warehouse projects, such as factory foundations, steel structure workshops, warehouse floors, logistics centers and production plant construction.
3. Tunnel and underground projects, such as road tunnels, railway tunnels, metro stations, underground passages, utility tunnels and pipe gallery construction.
4. Bridge and infrastructure projects, such as bridge piers, bridge abutments, pier caps, bridge deck slabs, culverts, highway projects and railway construction.
5. Water conservancy projects, such as dams, channels, pumping stations, spillways, irrigation projects and hydropower construction.
6. Precast concrete yards, such as precast beam production, wall panel molds, box culvert molds, concrete pipe production and large concrete component casting areas.
Crawler concrete placing boom with trailer concrete pump
The crawler hydraulic concrete placing boom is usually used together with a trailer concrete pump or stationary concrete pump. The concrete pump provides the concrete pumping power, while the crawler placing boom distributes the concrete to the final pouring location.
For medium-size foundation projects, building projects and tunnel projects, the crawler placing boom can be matched with a HAMAC diesel trailer concrete pump or electric trailer concrete pump.
For large foundations, bridges, water projects and long-distance concrete pumping projects, the crawler placing boom can be matched with a HAMAC high-pressure trailer concrete pump or stationary concrete pump.
HAMAC can also provide concrete delivery pipes, pipe clamps, elbows, rubber hoses, cleaning balls and other concrete pumping accessories for a complete concrete pumping and placing solution.
