Product Description1. APPLICATIONGDL-280 is energy
efficienctly. It solves the difficult problems of air DTH hammer
drilling in soil layers and low construction efficiency of rotary
drilling rigs for hard rock layers, gravel and pebble layers.Core

pump2.FEATURESa. The drill speed can reach 33-1120r/min, and the
maximum output torque is 9800N.m.b. The drilling rig adopts a
long-stroke double-speed mechanism, a mechanical power head, and a
power head stroke of 2300mm, which is used to improve drilling
efficiency and reduce the occurrence of drill blocking and burning
accidents.c. The drilling rig adopts double oil pumps for oil
supply. A single pump is used when drilling, and two pumps are used
for confluence when lifting and lowering the drill. The power loss
is small and the auxiliary time is short.d. The crawler chassis is
adopted, and the outrigger cylinder stroke is 1.5m, which can be
loaded automatically, which is convenient for relocation and
transportation. Detailed Photos We can also mount a
trailer chassis or crawler chassis on the rig. Main technical
