Concrete Boom Pump

A concrete boom pump combines a pumping system with a truck-mounted articulated boom that carries the delivery line towards the placement area. Its suitability depends on reaching the intended location from a feasible setup position while maintaining a suitable concrete supply.

The EPDAS HBC range here covers HBC28, HBC33, HBC37 and HBC47. The supplied matrix separates pumping-system entries, boom geometry and chassis data. Four-section M folding and five-section RZ folding configurations are documented.

The boom model designation alone is not an operating envelope. Review the reach drawing, unfolding requirements and support arrangement for the actual machine before choosing a configuration.

Four- and Five-Section Booms

HBC28 lists four boom sections with M folding. HBC33, HBC37 and HBC47 list five sections with RZ folding. These entries describe different arrangements; section count alone does not establish access beneath a roof or around an obstruction.

Horizontal Placement Requirement

The documented horizontal distances are 23.95, 28, 30.9 and 41.2 m. The actual reachable placement area depends on the permitted setup and boom geometry, rather than a circular area inferred from a single distance.

The source table contains two rows both labelled “Placing depth”, with different values. Their intended definitions remain unresolved. Both rows are retained exactly; neither is silently relabelled as certified vertical height or depth. Obtain the model-specific reach drawing to clarify them.

Theoretical pumping values and geometric entries are separate limits. Duplicate source boom labels remain unresolved; approved reach drawings, support data and actual chassis documentation are required for selection.

Concrete Pumping Package

The pumping section lists an S valve, cylinder dimensions, stroke-rate entries and theoretical output/pressure values. Where ranges appear, they do not establish a continuous combination of maximum flow and maximum pressure.

Boom and End Hose

The articulated structure positions its delivery pipe. End-hose lengths are listed separately: 2,800 mm on HBC28 and 3,000 mm on the other three models. A listed hose length does not authorize extensions or added tip loads.

Truck Chassis

The source includes chassis options, wheelbase, engine and overall vehicle dimensions. Confirm the exact chassis and final installed configuration in the order, including the relevant transport documentation.

Prepared concrete is supplied to the pump’s receiving system and conveyed through pipework carried by the boom. The boom changes the position of the delivery end within its approved envelope; the pump provides concrete movement through the line.

These are related but separate functions. A longer boom does not automatically provide a higher placement rate, and a high theoretical pump output does not resolve access to a restricted placement point.

This explains the general arrangement. Setup, boom movement, concrete delivery and cleaning must follow the actual machine’s manual and the site’s trained operating arrangements.

A workable setup needs space for the vehicle and its required supports, suitable ground and clearance from obstacles. The supplied matrix does not give a complete outrigger spread or support-load schedule; those details must be obtained for the selected model.

Do not infer partial-support permissions, unrestricted rotation or below-grade capability from the table or a photograph. A site-specific lift and placement plan must use the applicable machine information.

The table lists theoretical output entries of 68–90, 60–92, 80–120 and 140 m³/h by model. These describe the pumping specification, not a guaranteed completed-pour rate. Supplying trucks, material consistency and the placement crew can limit practical output.

Review pumpability and concrete acceptance with the producer and project team. A boom positions the line; it does not correct unsuitable concrete or replace proportioning and quality control.

Construction and Foundation Work

A truck-mounted boom can be assessed for placing prepared concrete where the setup position and working envelope allow the delivery line to approach the pour. Review the building geometry and the available approach before selecting a reach class.

Projects with Restricted Vehicle Access

Where truck access is impractical, a separate line pump or placing boom may deserve comparison. This does not establish that any alternative fits the project; it identifies a different arrangement to assess.

Check gateways, turning approaches, overhead restrictions and the vehicle’s installed dimensions. The HBC entries span different wheelbase and overall-length configurations, so access should be checked for the selected truck.

A boom must also unfold and move without relying on a nominal reach number alone. Confirm unfolding height, obstacle clearance, setup position and receiving-truck access from the relevant drawings.

The source describes EU-VI engine emission entries. Treat these as supplied configuration descriptions, not proof of registration or environmental approval for every destination. Verify the exact vehicle and its supporting documentation.

Arrange concrete washout and cleaning-water management at the site. The operating area needs sufficient room for the supply and placement equipment as well as the resources needed after the pour.

Boom structure, supports, hydraulics, pipework and pumping wear parts require the inspections specified for the actual machine. A general product page cannot replace structural inspection criteria or authorize repair methods.

Discuss manuals, inspection documentation, commissioning, training and spare parts with EPDAS. Chassis support and pump support should be clear in the supply agreement rather than assumed to be one unrestricted service commitment.

The useful comparison is the configuration that can serve the placement area from an approved support position. A larger nominal boom may bring different access, transport and support requirements as well as a different initial price.

Include chassis specification, wear parts, inspections and logistics in the ownership plan. No fixed fuel saving, setup time or cost per pour is established by the available matrix.
