Despite the compact dimensions, the firm claims that the machine offers same high performance and many of the same features as the larger truck mounted concrete pumps. It suits jobs in urban environments, residential jobs and compact job sites where space is limited.
Liebherr’s new city pump is said to meet a need for a reliable and flexible boom less pump truck for line pumping applications. The design and development of the THP80-LP city pump is a result of customer feedback in collaboration with Liebherr’s many years of engineering and production. The City pump features a 600litre capacity hopper, as well as compact construction and low weight.
The THP 80-LP offers greater flexibility and mobility to maneuverer around the job site. The total length of the new Liebherr city pump is around 8.66m. It is quick to set up and easy to control with an HBC option for the remote control. The truck has storage for the concrete tubes and accessories on the deck and contains plastic water tanks for saving weight. The THP 80-LP is mounted on a two axle truck chassis and weighs around 10.4tonnes. which is lighter than the truck mounted boom pumps.
The pumping kit features an open loop hydraulic circuit that is said to be simple, reliable and powerful. This system provides high performance and has low maintenance costs. The suction inlet has a greater diameter than the cylinder itself, ensuring high suction performance, even on extreme concrete types. With the split wear plates, maintenance can be carried out quickly and easily. In addition, Liebherr offers a pumping kit option that allows high pressure application for extreme tasks. Operators can switch the hydraulic hoses on the pumping kit, allowing the machine to provide higher pressure on the concrete. This pump the provides the standard hydraulic mounting with concrete pressure at cylinder rod side is 75bar, when switching connection, the concrete pressure at cylinder piston side is 125bar.
