Product Description

H420M Crawler Open-Air Down-The-Hole Drilling Rig (Hybrid Power)

Product Description 

1. Diesel-electric dual power output structure is adopted, which can be switched freely and work independently.
2. The electrical system is easy to maintain and the operating cost is low.
3. Imported walking motor is adopted, which has strong climbing ability and low failure rate.
4. The control console adopts an upper and lower double-layer structure, which is reasonable in structure and easy to operate.
5. The rotation adopts double motors with manual rotary valve to provide powerful speed and torque for the drilling rig.
6. The new hydraulic system increases the propulsion and rotation, increases the  speed gears, and improves the working efficiency. 

 

Product Feature

Slewing head
The slewing adopts a double-motor structure with a reducer, equipped with a manual rotary valve. It has two gears of high torque with low speed and low torque with high speed. The maximum output torque is 6000N·m.

Engine
Equipped with a 58KW four-cylinder diesel engine with strong power and a 55kw electric motor, which can be switched freely and work independently.

Console
The console adopts a double-layer structure with upper and lower floors, which is reasonably located and easy to operate. The new hydraulic system has fast and slow gears for propulsion and rotation, and a double-motor double-speed gyrator is used to meet the requirements of different working conditions.

Drill boom system
The design of the drill boom, guide rail and other structures are optimized to improve the structural reliability, flexibility and durability of the drilling rig. The minimum horizontal hole height is 300mm.

Filtering system
The use of pre-filter, oil-bath air filter and air filter for three-stage filtration provides a guarantee for the diesel engine to work in a high-dust environment.

Travel motor track frame
It adopts engineering travel motor, which has strong climbing ability and low failure rate.
