"G" Series Features

PANIC BAR

This device, which is Patent Pending, will allow the operator to instantly stop all hydraulic functions from outside the feed horn by simply grabbing the "Panic Bar". This system must be reset to eliminate any accidental reactivation of the hydraulic system which acts as a "lockout" to insure that it is safe to resume operations before the hydraulic system will operate. The bar is readily accessed from both the operator's position and from the direction of the chipper engine giving personnel almost 360° from which to activate it outside of the infeed chute. Activation devices from inside the infeed chute are not acceptable.

DISCHARGE DEFLECTOR / CHUTE ADJUSTMENT BAR

This device allows the operator to adjust the chip deflector and the discharge chute position without climbing on the chipper. This will reduce the opportunity for an operator to fall during adjustment and also facilitate proper chute and deflector placement.

CHIPPER HOOD SAFETY LATCH

This system reduces the ability of an operator to open the hood while the disc is still rotating. It also reduces the chance of an operator starting the unit with the disc hood open.

SOLID CHUTE ROTATION BRACKET

This enhancement will reduce the ability of operators to damage the chute rotation pin bracket.

CHIPPER HOOD LATCH

This feature allows the mechanic to latch the hood open at an angle of fewer degrees to help minimize the ability of careless mechanics to damage the hood when improperly released during opening and to reduce the ability of careless mechanics to over-spring the hood hinge point.

INCREASED AIR INTAKE SYSTEM

This improvement will assist operators by reducing the ability to clog the discharge chute.
