Product Specifications of DFHD-40Horizontal Directional Drilling Rig:
1. Introduction
DFHD-40 hydraulic directional drilling rig is driven with full hydraulic system, propelled with its own crawlers. With reasonable structure, easy operation, high efficiency; main hydraulic
components, motor and mud pump all selected and adopted from domestic famous-brand products as auxiliary equipments; with durable rubber belts of crawlers, the rig is suitable for
moving in the city with no injury of pavement.
2.Advantages
The DFHD-40 directional drilling rig is driven with full hydraulic system, propelled with its own crawlers.
Driven with duplex zero motors, the rotator could drill with two speeds with an advanced and
compact structure; adopting chain feeding system driven by motor, the motor could move stably
and reliably; the mast could be adjusted for the angle of drilling holes from 8°to 22°.
The overall unit is in low center of gravity and good stability with graceful structure; an auxiliary
crane equipped to the rig; a comfortable operation circumstance provided for the operator.
Basing on the idea of purchasing internationally, the main matching parts and auxiliary
equipments, such as diesel engine, hydraulic pumps, valves, motors, reducer and key hydraulic
accessories are all adopted in famous brand at home and abroad.
