Description
Detailed description
Description
Strengthen the dedicated chassis
Independently developed special chassis for telescopic tracks, with a wide operating span and 360 ° full rotation stability.
Hidden auxiliary support, strong anti overturning ability, suitable for heavy loading into rocks.
High strength box type drilling mast
Rectangular cross-section, wide guide rail, high-strength steel lightweight design.
Strong resistance to torsion and bending, no deformation when entering rocks, high guiding accuracy.
Large parallelogram amplitude mechanism
Wide width, heavy-duty structure, precise positioning, and even force distribution.
The hinge point uses heavy-duty self-lubricating bearings, which are maintenance free and have a long service life.
Dual motor power head
High torque, low-speed high torque, strong drilling ability in hard rock.
Multiple seals, patented extended drive chain, high reliability.
Ladder type main winch drum
The inner and outer layered rope groove extends the service life of the steel wire rope by about 1 times.
Neat rope arrangement, minimal wear and tear, and low failure rate.
