Sika® PM 622

The Sika-PM622 concrete spraying system has been developed for applications in which the previous spraying arm reach of 16 metres is not sufficient. The diesel-driven concrete spraying system, with its entirely newly developed carrier vehicle, can be put quickly to use anywhere, independently of an external energy supply.

Application
- mobile concrete spraying for wide tunnels
- excellent for slopes that reach a great height
- extremely flexible due to it not being dependent on external power

Modular design
- spraying arm
- concrete pump
- compressor
- liquid metering unit
- concrete additives reservoir
- high-pressure cleaner

Performance
- 4 - 30 m3/h wet mixture
- spraying arm 11 - 24 m reach
