Guide how to use hydraulic jacks correctly

Jack 0 is the simplest lifting equipment (shèbèi) with a small lifting height (less than 1m). Hydraulic wrench is the abbreviation of hydraulic torque wrench. It is powered by hydraulic pressure and provides high torque output. A professional bolt tightening tool for bolt installation and disassembly. It is often used to tighten and loosen bolts larger than one inch. A hydraulic wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe. It has mechanical and hydraulic (hydraulic) ) Type. Mechanical jack (Jack0 has rack type and screw type. Due to its small lifting weight and laborious operation and control, it is generally only used for mechanical maintenance and repair work. It is not applicable in the bridge repair process (guò chéng) The hydraulic jack (Jack0) has a compact structure (terse), works smoothly, and has a self-locking function, so it is widely used (extensive). The downside is that the lifting height is limited and the lifting speed is slow. When tensioning, open the front and rear oil nozzles, supply oil from the rear nozzle to the tensioning working oil chamber, and the tensioning cylinder cylinder moves backward. Because the cylinder cable is anchored to the jack (Jack0 layer part of the tool anchor, so the jack (Jack0 through ( The tōng guò) tool stretches the cable. When the cable is stretched to the required length, close the rear oil nozzle, and inject oil from the front nozzle into the top pressure cylinder, so that the piston of the top pressure cylinder extends forward and resists it. Anchor plug and press the anchor plug into the anchor ring to anchor the steel cable.
