Manufacturer supplies precision helical bevel gear lifting machines with multiple synchronized lifting platforms.

SNLThe screw jack, compared to the worm screw jack, boasts high efficiency, ease of adjusting the reduction ratio, and convenient installation and use. It is characterized by its compact size, lightweight, wide power source, noiseless operation, diverse functionalities, and high reliability. This series features an automatic locking function, allowing for precise control and adjustment of lifting or advancement height according to programmed settings. The structural designs are varied, and the lifting height can be custom-made to meet user requirements..

This lifting machine synchronizes the lifting of the base plate through corner movement, and connects it with a 4-point motion sequence, a 6-point motion sequence, and a 12-point motion sequence, reducing the height of the base plate while minimizing motion errors. Additionally, the flat lifting feature achieves direct and rapid performance, saving space, increasing production, and enhancing product quality stability.

SNBScrew Jack,Characterized by ball nuts housed within the casing, utilizing ball screws and nuts, made from hardened alloy steel, bearing the load between the nut and screw. This rolling action reduces friction between the nut and screw, allowing the load to move smoothly. Due to increased efficiency and rolling performance, ball screws can operate at higher speeds or over longer working 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 enhances high precision and speed, significantly boosting production capacity.

Ball screw lifting jackThe lifespan of the series products is primarily determined by the life of the ball screw and other components such as worm gears and worm; we mainly check the life of the ball screw, while worm gears and worms will experience wear, but generally have a longer lifespan than the ball screw. This elevator is widely used in high-precision environments and high-end automated equipment.

The working principle of the ball screw lifting mechanism brake is: one set of friction pairs is connected to the fixed frame; the other set is connected to the rotating shaft of the mechanism. When the friction pairs come into contact and are tightened, braking action is produced; when the friction pairs separate, the braking action is released, allowing the mechanism to move.

Ball screw lift mechanism brakes can generally be divided into normally closed and normally open types based on their working status.

1. Normally Closed: The brake is in a closed braking state when the mechanism is not in operation; upon operation, the control mechanism automatically releases the brake first. The lifting and jib mechanisms of tower cranes both utilize the normally closed type.

2. Normally Open: The brake is in a released state under normal conditions. It requires a mechanical or hydraulic mechanism to engage when braking is needed. The tower crane, construction hoist, and the reversing mechanism of the construction hoist reducer all use the normally open configuration.
