Concrete Machinery HBT70D

It is driven by diesel engine. The main pumpingsystem is equipped with open loop, constant control, pressure cut protection. Italso can realize the infinitely variable speed of the master hydraulic cylinderand adjust the concrete output.

All hydraulic pumps and main valves are originalGerman Rexroth products.

The high and low pressure conversion of the outletpressure can achieve large discharge at low pressure and small discharge at highpressure so different conveying distance and height can be realized.

Powerful and low-noise Deutz diesel engine.

The reversing control is electric-hydraulic type.The electric part is controlled by PLC, which is reliable, more accurate withsmall impact.

The counterforce on specially designed S” valve isreceived by hopper wall to assure the service life of goggle plate and cuttingring.

Control mode: manual operation and wireless remotecontrol.

Reverse pumping function can facilitate cleaningthe conveying pipe.

Unique mixing unit can achieve homogeneous mixingof different proportioned concrete so as to realize ideal pumping effect.

Automatic lubricant filling device can eliminatethe trouble of manual filling and extend the service life of the parts with lessabrasion in the lubricants.
