Hydraulic Anchor Cable Tensioning Jack
Hydraulic Anchor Cable Tensioning Jack uses working oil with a kinematic viscosity of 12-60mm2/s at 50℃, impurity diameter not greater than 130μm and certain anti-rust ability. Before use, check whether the oil used in the oil pump meets the requirements.
- Product Introduction
Product Introduction
1. Hydraulic Anchor Cable Tensioning Jack uses working oil with a kinematic viscosity of 12-60mm2/s at 50℃, impurity diameter not greater than 130μm and certain anti-rust ability. Before use, check whether the oil used in the oil pump meets the requirements.
2. When using, first insert the anchor cable from one end of the top pressure device, then inject oil from the oil inlet Ⅱ to increase pressure, and the jack gradually tightens the anchor cable. After tightening the anchor cable, stop injecting oil and inject oil from the oil inlet Ⅰ instead. Under the action of oil pressure, the jack recovers, remove the jack, and the operation is completed.
Working Principle
Hydraulic Anchor Cable Tensioning Jack is powered by a pneumatic oil pump, which is transmitted through pipelines and the jack is used as an actuator to tighten the anchor cable. The pneumatic oil pump works with compressed air as the power. It outputs high-pressure power hydraulic oil through the reversing valve and enters the actuator tension jack. The high-pressure oil acts on the outer cylinder and the core shaft. The claws lock the anchor cable while the jack presses the anchor to achieve the anchor cable pre-tightening operation.
