JACK LEGS CHINA STANDARD
APSARA-28 JACK LEG
Drilling Depth : 5m
Unlike conventional jack legs designed primarily for maximum drilling speed, APSARAS-28 Jack Leg Rock Drill under China standard for underground face drilling, tunnel construction, and rock bolting, features a sound balance between the leg and the drill. It is designed for underground drilling only. This ensures stabilized operation through a wide range of drilling angles. Moreover, the leg absorbs the drill vibrations so effectively that the operator can use it for many hours of fast drilling operation without excessive fatigue. Another feature is the concentration of all controls on the back head of the jack leg. This enables the operator to control the leg drill quickly and easily. The leg is as lightweight as it can be. |
