The concrete spraying machine type CB 130 has a universal character. It can be used in both building and underground construction. It has a significant use in civil engineering works, during special foundations, securing slopes, reinforcing the walls of pits, collectors, galleries, etc.
- applicability of the machine for wet concrete spraying
- easy operation and maintenance of the machine
- robust construction enabling work in demanding conditions
The operating part of the pump consists of two opposing working plungers driven by straight hydraulic motors and a shifting mechanism, the so-called S-pipe. The hopper (tank) is equipped with a grate with 30 mm slots, a stirrer, and a vibrator. The outlet from the hopper is 80 mm in diameter. The high-pressure hydraulic circuit consists of the main pump, hydraulic accumulator, hydraulic motors, oil tank, and oil cooler. The pump is driven by an electric motor or a diesel engine. The pump frame can be constructed as fixed, wheeled, or railed. The machine is equipped with a pump for dosing additives (with an integrated flow meter) for the purpose of spraying concrete in the so-called wet method. For easier maintenance, CB 130 can be equipped with a water rinse pump as well.
