Hydraulic bolt tensioner TYD-MSD42

multi-stageautomatic

MSD series multi-stage hydraulic bolt tensioner is a high-quality hydraulic bolt pre-tightening and dismantling tool, which precisely controls and guarantees the pre-tightening force of the bolt connection. It is an ideal tool to improve the quality of bolt connection and improve labor efficiency; multi-stage hydraulic tension The diameter of the device is small and the tensile force is large, which is suitable for the pre-tightening of bolts in small spaces, especially the pre-tightening of imported bolts (grade 10.9 bolts). Widely used in metallurgy, machinery, chemical industry, power station, shipbuilding, cement, coal, pressure vessel and other machinery and equipment assembly, installation and maintenance. MSD series multi-stage hydraulic bolt tensioner is made of high-quality alloy steel, the maximum working pressure is 150MPa, the pre-tightening force is displayed by the pressure gauge of the special hydraulic pump station, which can be used to tighten or remove the nut, and the high-pressure hose is connected by a quick joint, It is easy to operate and use; the same two-stage hydraulic tensioner can be equipped with different specifications of tie rods to be suitable for different specifications of bolts, reducing the number of tensioners as much as possible, thereby reducing economic costs. Features: - Mainly used for 10.9 grade bolts - Maximum working pressure 15OMPa - Automatic quick return mechanism - Red travel indication line, over travel indication - Replaceable stretch head - Polished finish (blackened) - Overtravel Limiting Mechanism
