摘要

The three-wheel grave excavator with portal structure is for right-angled entry into cemeteries from narrow paths where different cemetery layouts and gravestone heights are involved. All three drive wheels are steerable and driven. The two front wheels are rotatable through 90 degrees and when necessary are individually steerable. The adjustable rear wheel (4) with steering shaft is screwed to an adjustment device (1) which in turn is screwed to the lower part of the vehicle. Standing security of the machine is ensured by alteration of the adjustment device by a multiple hydraulic support (6). The portal movement mechanism is equipped with a hydraulic inclination adjustment (8) and stabilization on the front axle. The front axle when necessary can be additionally mechanically widened.
