Overview of stationary concrete pumps Crawler concrete pumps The crawler concrete pumps are particularly suited for building site applications in which the working position is regularly changed. • Low-emission, environmentally-friendly engine (Tier 4i) • Large, protected suction opening for optimum cooling performance • Large-sized cover for easy access to all components • Remotely-controlled crawler drive allows flexible manoeuvrability on the building site  Stationary Concret

Trailer-mounted concrete pumps The trailer-mounted concrete pumps are ideally suited for arduous applications on large or small building sites across the globe. • Specially formed discharge hopper for optimum concrete flow • Two independent agitator motors channel the concrete to the suction opening • Solid, torsionally-resistant basic frame • Powerful and smooth-running pump unit • Rugged, fully-galvanised support feet  Stationary Concre

Perfectly designed for everyday building site applications The entire design was conceived with everyday use on any building site throughout the world in mind, whether in 40° Celsius weather in Dubai, or extreme winter conditions in Russia.  Stationary Concrete Pumps

The pump unit is mounted on an extremely rugged steel frame. A sturdy sheet metal housing ensures protection against the weather and noise reduction. A large steel grid provides protection for the cooling system in the suction area and guarantees reserves for cooling performance. All components are compactly integrated and encased in a state-of-the-art design. Rapid discharge of the hopper The large-sized, sturdy gate on the base of the receiving hopper allows speedy discharge of residual concrete and easy cleaning. Optimum concrete flow Largely-dimensioned and robust conveyance lines with...

Adaptable for applications on all building sites Liebherr stationary concrete pumps require only minimal space on the building site, are quickly set up and can be positioned anywhere. Regardless of the height or distance being pumped, the control of the pumps guarantees maximum versatility.  Stationary Concrete Pumps

Concrete placement A climbing mast or a rotary distributor attachment allow quick and cost-effective placement of concrete. Concrete distributor systems and concrete pumps from Liebherr are designed to work in perfect harmony with one another. Mixing, transport and pumping of concrete – Liebherr provide it all in one. Concrete pile foundations The Liebherr THS 110 D-­ with drilling equipment for concrete pile K foundations. Concrete elevation requirements Liebherr trailer-mounted pump THS 80 D fulfilling concrete elevation requirements on a tower block building site.  Stationary Concrete...

Aluminium cover as spray protection An agitator on either side without connecting shaft for optimum concrete flow Sectioned discharge hopper with replaceable upper half Large water container simplifies access for maintenance Conveyance piston made from special rubber Chrome-plated conveyance cylinder S-pipe made from highly wear-resistant cast steel Powerful and smooth-running pump units Liebherr employs an open hydraulic circuit. This system is reliable, easy to maintain and does not require pressure storage.  Stationary Concrete Pumps

S-pipe system A dual-pivoted S-pipe with adjustable axial stop forces the concrete from both conveyance cylinders into the conveyance line. The design is particularly impressive due to minimal concrete deformation, reduced pressure loss and low wear. Largely dimensioned • Large-sized suction openings on the cylinder facilitate smooth pump operation and outstanding suction performance. • Largely-dimensioned hydraulic cylinders allow a powerful switchover with hydraulic pressures of up to 320 bar. Long life-expectancy of the bearing and seal surfaces attributable to automatic and stepless...

Variable hydraulics Oil supply on piston side = High concrete pressure Oil supply on rod side = High concrete delivery rates Quickly adaptable to application requirements The hydraulics can be reset between higher delivery rate or higher pressure in accordance with the respective application. A special hydraulic connection plate simplifies this changeover.  Stationary Concrete Pumps

Optimum pump configurations Liebherr stationary concrete pumps are available in diverse configurations depending on type and hydraulic oil supply: • Oil supply on piston side: Piston functions more slowly with more power = High concrete pressure for greater heights • Oil supply on rod side: Piston functions more quickly with less power = High concrete delivery rates Hydraulic control • Electro-hydraulic sequence control with automatic stroke adjustment. • Switchover of drive cylinder and S-pipe is executed auto­ matically via end position sensor control. rod side piston side Pump output...
