Helical screw lifters (bevel gear screw lifters) are applicable in various industries such as machinery, metallurgy, construction, hydraulic engineering, chemical industry, culture, and public health. Examples include: lifting platforms for heavy-duty clamping devices in machine processing, flip mechanisms, and plastic processing machines; climbing ladders and tool lifters for installation and maintenance, engine maintenance lift platforms; adjusting the gap in rolling mill tracks, positioning pipes or plates; mold opening or concrete shaping in foundry; adjusting electrodes and hot liquid casting in metallurgy; moving templates and assembling finished products in construction, including adjustable windows, walls, and fences; adjustable stages and pool floor heights for cultural and health purposes; gates and protective plates for reservoirs in hydraulic engineering; and for scientific research, where manual adjustment is not feasible.
Structural Type:
Hoist structure type:
Type 1 - Screw shaft for axial movement.
2 Type - The screw rod rotates, and the nut on the screw rod moves axially.
2. Assembly Type:
Each type of elevator structure is further divided into two assembly types.
Type A - Screw (or Nut) Moving Up
B-type - screw (or nut) moves downward
3. Screw Nut Type:
1 Type screw head structures include: I (cylindrical), II (flanged), III (threaded), IV (flat head) in four styles.
The structural styles of the screw head for Type 2 are: I (cylindrical) and III (threaded).
4. Specifications:
Divided by lifting force: 2.5, 5, 15, 20, 35, 50×10KN, eight types
5. Transmission Ratio:
The elevator is divided into two types based on lifting speed: standard and slow, with slow indicated by 'l' and standard not marked.
6. Screw Protection:
The protection of the I-type lifting machine screw is divided into: Basic Type, Anti-Rotational Type (F), and Enclosed Type (Z).
SNBScrew Jack,Characterized by ball nuts housed within the shell, utilizing ball screws and nuts, made from hardened alloy steel, and carrying the load between the nut and screw. This rolling action reduces friction between the nut and screw, ensuring smooth and efficient movement of the load. Due to improved efficiency and rolling performance, ball screws can operate at higher speeds or longer work cycles compared to standard trapezoidal screw lifts.
High-precision screw jack, suitable for industries such as stainless steel precision plate and wafer panel manufacturing. Saves space and significantly increases production capacity by enhancing high precision and speed.
SNLThe screw jack, compared to the worm screw jack, boasts high efficiency, easy adjustment of the reduction ratio, and convenient installation and use. It is characterized by its compact size, light weight, wide power source, noiseless operation, diverse functionalities, and high reliability. This series features an automatic locking function, enabling precise control and adjustment of lifting or advancing heights according to a program. The structural forms are varied, and the lifting height can be customized to meet customer requirements..
