SNLThe screw jack and worm gear screw jack are primarily characterized by high efficiency, easy adjustment of the reduction ratio, ease of installation and use, compact size, lightweight, wide power source, noiseless operation, diverse functions, and high reliability. This series of products features an automatic locking function, capable of accurately controlling and adjusting the lifting or advancement height according to a program. The structural forms are varied, and the lifting height can be customized according to customer requirements..
This lift synchronizes the lifting of the base plate through corner movement, and connects it with four-point, six-point, and twelve-point motion chains to lower the base plate height, reducing motion errors. Moreover, the flat lifting feature allows for a direct and rapid achievement of efficiency, saving space, increasing output, and ensuring higher 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 enhanced efficiency and rolling performance, ball screws can operate at higher speeds or over greater work cycles compared to standard trapezoidal screw lifts.
High-precision screw jack, suitable for industries such as stainless steel precision plate wafer and panel manufacturing. Saves space and improves high precision and high speed, significantly enhancing production output.
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 in a non-operational state; during operation, the control mechanism first automatically releases the brake. The lifting and jib mechanisms of tower cranes both use the normally closed type.
2. Normally Open: The brake is in a relaxed state under normal conditions. Braking is achieved through a mechanical or hydraulic mechanism as needed. The rotating mechanism of tower cranes and construction hoists, as well as hoist reducers, employs the normally open design.
