MQ18-350/66 mining anchor cable and back tension machine
Product: Pneumatic anchor cable and back tension machine
Type: MQ18-350/66
1. Product details:
Pneumatic anchor cable and back tension machine is combination of peneumatic hydraulic pump and back anchor tension jack. Jack can complete these automaticly: seize the anchor, load tension, boost and lock anchors under the drive of hydraulic pump, it is necessary during unloading tension and loosing the cable anchor. Since the main power sourse is high pressure gas, so explotion-proof function is very well.External characteristic for the vane type motors makes that the machine Just meet the demand of tension ,it has this advantage that the tension speed is fast in the earlier stage and slow in the late. Especially used in the work of releasing the prstress of the roof for coal and tunnel,solve the caving problem quickly in the goaf and wind in and out area.
