GM 140-AFH – 500

Our new „Grabenmeister GM 140 AFH-500“ is equipped with a hydraulic  turntable, enabling the offset for trenching beside the excavator. The use of a offset Trencher is necessary if the Trench goes directly to the trench / or behind obstructions such as guard rails, falling or rising slopes, hedges, walls similary.

A major advantage of the new GM 140 AFH-500 is, that the Trencher is equiped with a conveyor belt that can be placed on both sides (left or right as needed). By the conveyor the discharge of the excavated soil will be excavated from the edge of the Trench and keep free the sides of this. So the excavated soil still on the right side of the Trench to be easily backfilling.

The structure of the GM 140 AFH-500 was designed to be extremely flexible and by etablishing fast-changing systems in the shortest time mounted or dismounted to the excavator. So that the using of the GM 140 AFH-500 is very interesting also for short trenching dimensions.
