Model
DW1203 Rock Drilling Jumbo
  • Section area: 13*9m
  • Boom: 3
  • Overall weight: 48,400 kgs
Description
Summary
DW1203 rock drilling jumbo is applicable in tunneling and bolting in the fields of mining, hydroelectric power, railways, highways and other fields. The machine adopts full hydraulic drive and an anti-sticking drill device. The two booms could be retractable, which can be relatively parallel to the operation section for multi-angle and multi-directional drilling positioning. Climbing capacity ≤18°, walking speed up to 15km/h with compact structure and fast transition speed.
Characteristic
· Three booms can be operated at the same time, extending a wide range and reducing construction costs.
· One aerial work platform can improve the the efficiency of aerial operations and make the bolting and grouting faster.
· Hole alignment is accurate, reducing the problem of missing hole and off-hole in construction, and the integrity of blasting can be greatly improved.
· Rock falling and strong bending resistance, the compact structure can protect the safety of construction personnel.
· The simple and convenient hydraulic control console provides a good view of operation, so that the operator can get started faster.
