4.2.2
Function of the truck-mounted concrete pump
The concrete is delivered into the hopper and is pumped by the concrete pump through the S-valve and the
conveying pipework to the discharge hose.
4.2.2.1
Distributor boom
All distributor boom functions are hydraulically actuated.
The conveying and riser pipes comprise pipes and pipe elbows.
Snap couplings allow the pipes to be joined together and the joints to be rotated.
4.2.2.2
Outriggers
The rear outriggers are swung out hydraulically. The telescopic front outriggers are hydraulically swung out and
extended. The hydraulic support cylinders ensure the necessary stability of the truck-mounted concrete pump.
The rear outriggers contain the water tanks with a capacity of 400 litres each.
4.2.2.3
Control
The controls actuate the hydraulic systems for the concrete pump and distributor boom. The operator can use
the controls either at the control panel or at the remote control pendant.
4.2.2.4
Central lubrication
The central lubrication system is operated by compressed air from the pressure accumulator on the vehicle
chassis. It supplies all lubrication points on the truck-mounted concrete pump (apart from the conveying piston).
An optional central lubrication system is available for the conveying piston and/or distributor boom.
