The QQP series pneumatic spiders are mainly applied to hold the drill pipes and tunings for their couplers fastening and removing during the oil well repairing operation. The cylinder, which is driven by the compressed air, activates the slip body lifting and lowering action, thus it largely reduced the workers working strength and increased the working effect. It is safe and reliable, easy in operation, and rational in structure, which is an ideal tool for the oil well repairing operation. These are manufactured as per API Spec 7K.
