Concrete Trailer Pumps – SP 1200 / SP 1200 HD / SP 1400 / SP 1600

Drive 

The motor (Diesel or Electric) drives the axial piston pump via a flexible coupling. Due to automatic output adjustment optimum  utilization of the motor power, resulting in low energy   consumption at  differing   pumping   condition. Additionally the concrete flow can be manually  adjusted. The pump operates in a proven open circuit.

The  maximum   placing   output   and  the   pressure   are determined  by the construction sites. Between these two values automatic  adjustment  by  the governor   occurs maintaining  a  constant  output  depending on  the  power available from the installed drive motor.

Design

The portable concrete pumps are assembled in the unit construction system.  The main assembly groups are: Frame, Power unit, Concrete pump kit, Control block, Hydraulic tank and Hopper with agitator.

Concrete Trailer Pumps – SP 1800 / 1807 / 2000

SCHWING portable concrete pumps are successfully deployed worldwide wherever vast quantities of concrete have to be pumped over exceptionally long horizontal and vertical distances. In building and civil engineering projects, they are also fast, reliable and economically efficient in handling pumpable concretes under extreme conditions with regard to concrete designs, job sites and climate.

Compact class, High performance & High fuel efficiency

The Rock Valve

RL-Rock valve, is a new generation Rock valve, Engineered by SCHWING R&D after extensive studies of behavior of tough concrete in various developing countries. This rugged, reliable rock valve is highly suited for stiff, difficult mixes of concrete and ideal for use in combination with the long stroke pumping unit. An option that can be recommended is the hard facing layer for extremely long service life.

Integrated Control Block

The hydraulic control system is integrated within the drive. The compact control block & minimal hydraulic lines makes the equipment Reliable & durable.

Fast Switching Valve

Compact design individual switching circuit ensures quick operation of rock valve.

Remote Control

The Concrete pump comes complete with a 10 meter cable remote control as a standard feature.

Hydraulics

All SCHWING concrete pumps have an output governed hydraulic pump that ensures that the prime mover is never overloaded, the automatic governor splits available engine output optimally into oil flow and oil pressure and allows the concrete pump to run at the best possible output level. At the same time, the manual de-stroker valve can be used to set the pump to a required fine tuning to set stroke rate and output independent of the automatic governor. The open circuit, combined with the SCHWING designed “Hi-flow” spool block ensures minimum heat generation in the hydraulics, therefore there are negligible output losses and minimum stress on the hydraulic components.

Easy Maintenance

The easy access to all the parts of the machine ensures that maintenance requires the minimum time for maintenance so your machine is up and running in no time at all.

Pumping

The pump has two powerful differential and pumping cylinders. The prodigious combined capacity and performance of these cylinder systems ensures a high output. Our pumps are designed to offer you maximum output with minimum number of strokes to increase the life of the cylinders.

The Frame & Axle 

The frame, in compact execution, is constructed from standard vehicle profiles. The pump is mounted on heavy duty single axle chassis with draw bar, pneumatic tyres and for travelling on construction sites at up to 25 km/hr.

Control System 

The fully hydraulic control system is integrated within the drive. The compact control block and minimal hydraulic lines makes the equipment reliable and durable. The differential cylinder has trouble free piston rings and automatic constant stroke maintenance. Both gate valves change independently so that even when full change over is prevented by foreign material or similar obstructions  in the concrete, the pump continues to operate without problems. All components are especially developed and manufactured to withstand the rough treatment on construction sites.

Control Housing

Ideal flow conditions in the control housing resulting in superior placing proper ties also incase of concrete low on sand and fines, stiff consistence or crushed aggregates. Simple tilting of the output pipes enables easy control and cleaning of the concrete conveying path and the gate valve parts.

Pumping Material

Pumpable concrete, within any consistency range down to a water cement ratio of 0.4. Even concrete with aggregate grading up to 40mm can be conveyed  trouble  free with the concrete  pump through a 125mm diameter pipe line.

Flat gate valve

The  two flat gate  valves working   independently  have  been especially developed for pumping concrete. Their working system with automatic adjustment permits trouble free pumping even with badly worn parts.

Integrated Control Block 

The hydraulic control system is integrated with in the drive. The compact  control  block  & minimal  hydraulic  lines makes  the equipment reliable & durable.

Schwing SP 8800

The epitome of concrete pumps, the Schwing SP 8800 is the most powerful pump in the world. The choice wherever concrete has to be pumped to record breaking heights. This pump has the Rock Valve and open hydraulics as all Schwing pumps. The Schwing philosophy of green pumping is built into this pump and it is designed to use the minimum amount of fuel for it’s operation ensuring a healthy economy as well as a healthy environment.

Also the noise shielding features ensure that the pump noise is reduced. The ergonomic control panel displays all operating data and the intuitive interface enables the operates to learn using the pump quickly. Another advantage of using Schwing is the experience we have for the past 83 years in concreting.
