Hydraulic Wedge Jack

The hydraulic wedge jack is the special rescue equipment for lifting the loads and enlarging the narrow seam. It must be connected to the hydraulic power unit to implement the rescue operation. The tool is often used in the rescue for collapsed building and firefighting. When releasing the people or objects trapped in the collapsed building, the rescuer can create a large seam with the tool at the needed position as the rescue openings to allow the other rescue tools to go in and save people quickly.

Features

the hydraulic wedge jack can provide spreading force up to 210KN. The material of high-strength light alloy for aerospace and special steel are used to make

Application Case

The Case of Cooperation with the Hydraulic Spreader

Cautions
1. The safety valve and hydraulic lock on the hydraulic cylinder are very important for guaranteeing the hydraulic wedge jack working safely. The users are not allowed to adjust them arbitrarily.
2. The slotting spring board should be inserted into the seam deeply enough and contact with the work piece firmly to avoid slippage danger.
3. When the hydraulic wedge jack lifts the loads to enlarge the seam, the operator should notice the position of center-of-gravity of the work piece in order to avoid the work piece tipping over and causing injuries.
4. If the foreign matter goes into the contact surface of the wedge block and slotting spring board, the working efficiency would be affected. The operator should avoid that situatian happening as much as possible.
5. The tool is often used to enlarge the narrow seam through the wedge block lifting the loads and it’s not designed for long time supporting.
