Title:
削岩リグおよび下り坂運転方法
Document Type and Number:
Japanese Patent JP5613322
Kind Code:
B2
Abstract:
The invention relates to a rock drilling rig and a method for downhill driving of a rock drilling rig. The rock drilling rig comprises electric drive equipment, the drive motor of which serves as a primary brake in long-term downhill driving. The drive motor thus converts kinetic energy into electric energy, with which an energy storage is charged. To consume surplus electric energy, a hydraulic system or a compressed air system is turned on. A hydraulic pump and a compressor (54) are driven by an electric motor.
