SWL worm screw jack
Product Overview:
Shanghai Guzuo SWL series worm gear screw lift is a basic lifting equipment, which
has many functions such as lifting, lowering machine with auxiliary parts to advance,
overturn and various height position adjustments. And other industries.
Advantages:
SWL series worm gear screw lift specifically has many advantages such as compact structure, small size, light weight, wide power source, no noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability, long service life, etc. It can be used individually or in combination. It can accurately control the height of the lifting or advancing according to a certain program. It can be driven directly by a motor or other power or manually. There are different structural forms and assembly forms, and the lifting height can be customized according to user requirements.
Form and specification machine representation method:
1. Structural form:
Type 1 --- the screw moves axially; [when the screw moves, it is divided into rotating and
non-rotating (F), please pay attention to the distinction when selecting the type
Type 2 --- The screw rod performs rotary motion and the nut performs axial movement.
2. Assembly form:
Type A --- the screw or nut moves up
Type B --- the screw or nut moves down
3. The form of the screw head:
There are four types of screw heads in type 1 structure:
type Ⅰ (cylindrical), type Ⅱ (flange),
Type III (thread type), type IV (flat head type).
There are two types of screw heads in type 2 structure:
type I (cylindrical) and type III (threaded).
4. Transmission ratio:
Normal speed ratio (P), slow speed ratio (M)
5.Lifting capacity
1 , 2.5 , 5 , 10 , 15 , 20 , 25 , 35 , 50 , 100 （×10KN）
6、Protection of screw rod：
Type 1 structure includes basic type, antirotation type (F) and protective cover type (Z);
Type 2 structure has basic type

Note: The parameters in the table are obtained under the condition of ambient temperature of 20 ℃ and continuous operation of 20% per hour or 40% per minute;
When the speed exceeds the value in the table, the lifting element will wear out early due to overheating, so pay careful attention when using it.
