Double-walled design

Double-walled design

Double-walled steel housing for chipper disk tunnel

What happens, when stones or metal parts are fed to a tracked chipper by mistake? And at the high speeds typical for wood chippers?
Tremendous load would be applied to materials installed in the turning circle of the chipper disk. The cutting system might be damaged or even destroyed. In the worst case, material could exit uncontrollably from the chipper disk housing.
To ensure that such a danger potential does not exist in the JBM tracked chippers, we do not only comply with the legally prescribed material thickness, our upper and lower chipper disk tunnels are designed with double walls.

Safety operator handle and feed hopper dimensions according to EN 294 and EN 13525

Compliance with the safety clearances and installation of the safety operator handle according to the current safety standards enables easy and safe operation.
The circumferential safety bar is the most effective protection against the operator being caught unintentionally by the feed rollers: If reaching into the hopper area too far, the operator moves the operating handle with his legs or arms into the stop or reverse position.
All functions, such as feed, stop, and reverse, can be easily operated from any operator position.

Gas pressure spring for upper tunnel

The massive upper tunnel can be easily opened with the help of a gas pressure spring. This allows quick, easy, and safe access to the cutting system.
