WSH series worm is a basic lift crane lifting features. Widely used in machinery, metallurgy, construction glass, woodworking, chemical, medical, cultural and health industries. Four, WSH series worm screw lift specific models WSH-2T, WSH-3T, WSH-5T, WSH-10T, WSH-15T, WSH-20T, WSH-30T, WSH-40T, WSH-50T, WSH-100 SWL screw lift can be self-locking, it is divided into different forms according to different structures: one, SWL screw lift lifts by structural type structure is divided into: 1 type - screw while for rotary motion and axial movement; type 2 - screw rotational movement. Screw on the nut to move axially. Two, SWL screw lift assembly type screw lift each assembly structure type is divided into two types: A type - screw (or nut) to move up; B type - screw (or nut) downwards. Three, SWL screw lift the screw head type 1 type structure type of screw head is divided into: I (cylindrical), II (flange type), III (screw-type), IV (flat head type) four types . Type 2 structure type of screw head is divided into: I (cylindrical) and III (screw type) in two forms. Four, SWL screw lift lifts ratios divided into two ratios, namely ordinary (P) and slow (M). Five, SWL screw lift screw protection. Type 1 lifts screw protection is divided into: basic, anti-rotation type (F) and with a shield-type (Z); type 2 lifts screw protection is divided into: basic type and with shield-type (Z). SJA screw lifter (SJA screw jack) Features thrust range: 0.5 to 30 tons - up to 8m travel gear, have to consider the stability of the screw and guide mechanism - duty of 30%, if the load was smaller WS Worm Reducer machines, you can improve the system appropriately - Lifting speed of less than 1500mm / min (23mm / s), special circumstances can reach 46mm / s- efficiency is less than 33%, self-locking function, large reduction ratio L1 absolute self-locking - precision positioning, Additional anti-backlash means to 0.05mm- absolute synchronization accuracy, the same motor can drive multiple screw jacks, mechanical synchronization - can be equipped with an encoder, limit switches, dust cover, safety nut, gear WHC worm reducer, general motors, servo motors, stainless steel, etc. - simple operation and maintenance, low noise WS worm reducer gearbox _ _ Runchi by the Texas Runchi gear reducer Limited. Texas Runchi reducer Limited (www.sddzjsj.com) is a leader in Dezhou, reducer, transmission, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Runchi reducer leadership with the staff warmly welcome all inquiries negotiations to create Runchi reducer better future.
