Product Description

QWL/SWL series worm gear screw jacker, is through the worm gear drive screw lifting, lowering, propulsion, fliping, and other functions, is a kind of basic lifting parts, has been listed as a standard JB/T8809-1998, Widely used in machinery, metallurgy, water conservancy, chemical industry, medical treatment, culture, health and other industries, has a compact structure, small volume, light weight, easy installation, flexible use, good reliability, high stability, long life and other advantages, can direct drive motor or other power, can also be operated manually. This series worm gear screw jacker can be self-locking, carrying capacity is 2.5 t ~ 120 t, the top input speed of 1500 r/min, the maximum speed is 2.7 m/min, there are different ways of structure and assembly, working environment temperature between - 20 ~ 100 ºC, hoisting height according to user requirements.


JINXIANG improved the efficiency of the QWL/SWL series worm gear screw jacker and carrying capacity, use with the hollow flank cylindrical worm which is the domestic advancedlevel, made a special advanced technology to improve the comprehensive performance of the elevator, to meet the requirements of the customers.

JINXIANG technical force is abundant, the development of industries such as metallurgy, chemical industry, water conservancy specifications for AGQWL20 oscillating screw jacker has won the national patent. (patent no. 02219626.9).


structural type

  • Type 1 - worm gear and screw thread connection,
  • Type 2 - worm gear and screw for linkage, on the screw nut.


Assembly type
Elevator each structure is divided into two kinds of assembly type:
There are two kinds of structure forms of type 1 assembly type:

  • Type A: screw work carry on;
  • Type B: screw work next;


There are two kinds of structure forms of type 2 assembly type:

  • Type A: screw in the work end, nut on the top or the drop-down;
  • Type B: next screw work end, nut on the press or pull;


Holdings screw head type

  • Type 1 structural type screw head is divided into I type (cylindrical), II type (flange), III (threaded) and IV (flat head type) four types (see figure 1).
  • Type 2 structural type screw head type is divided into I (cylindrical) and III (threaded) two type (see figure 2).
