The GBPH is a hydraulic tilting grading and ditching bucket for mini and midi excavators. It tilts up to 45 degrees to each side, so ditches, slopes and banks can be cleaned and shaped without moving the machine.
About this family
The Hydraulic-Tilting Grading and Ditching Bucket is made for mini-excavator grading tasks such as ditch cleaning and contouring. It tilts up to 45 degrees for work on uneven terrain and fits excavators from 1.2 to 10 tons. The bucket has full-length bottom wear pads and replaceable pivot bushings. A reversible bolt-on cutting edge and spill guards are options.
Six sizes cover machines from 1.2 to 10 t, GBPH-20 through GBPH-95, in widths from 900 to 1800 mm. Capacity runs from 68 to 511 litres (SAE) and weight from 76 to 370 kg.
A double pilot check valve holds the tilt angle. The bucket has an HB500 cutting edge, an inner reinforcement rim, a top bent section, standard hydraulic connectors on the adapter plate, replaceable bushings, drainage holes and protected weld seams at the bottom. Options are a reversible HB400 cutting edge, a rear HB500 cutting edge, wear bars, a cylinder guard or spill guard, an additional reinforcement bevel, HB500 cutting edges on the front sides and a recessed bracket for higher breakout force.
The quick coupler bracket follows the size, from S30, MS01, M02, HS02 and Klac C on GBPH-20 up to S45, S50, MS08, M10, HS08, CW10, OQ45 and Klac F on GBPH-95.
