Outline
SWL series worm screw lift, also known as QWL lifts are widely used in machinery, metallurgy, construction, water conservancy facilities and other industries, with lifting, descent, and advancing with accessories, flip, and a variety of height adjustment and many other features. SWL worm screw lift is a basic lifting unit, with a compact, small size, light weight, power source extensively, no noise, easy installation, flexible, multi-function, multi-format support, high reliability, long life and many other advantages. Can be single or in combination, can be accurately controlled by adjusting certain procedures to enhance or promote the height, you can use direct drive motor or other power can also manually. It has a different structure and assembly forms, and lifting height according to user's requirements. . The device can be self-locking.
Features:
Using the screw drive scissor lift bodies, with the characteristics of snorkels, and no oil pollution, especially suitable for the work environment requires a higher workplace, you can choose different forms of work table (without power roller. Electric drum , ball, wheel, telescopic, tilt), to frequent movements, with electrical, mechanical and other safety devices.
Type and mark
Structure type
Lift by structure type is divided into:
Type 1 - the screw rotates simultaneously and axial movement;
Type 2 - screw rotates. A nut on the screw for axial movement.
Assembly type
Each lift assembly structure type is divided into two types:
A type - screw (or nut) to move up;
Type B - screw (or nut) down.
Screw Head Type
A type of screw head type structure is divided into: I (cylindrical), II (flange type), III (screw-type), IV (flat head type) four types.
Two types of screw head type structure is divided into: I (cylindrical) and III (screw-type) in two forms.
Drive ratio
Lift divided into two transmission ratio, ie normal (P) and slow (M).
Screw protection
A screw-type lift protection is divided into: basic, anti-rotation type (F) and with a protective cover type (Z);
2 screw-type lift protection is divided into: Basic and with a protective cover type (Z).
