升降机的方形凹槽壳体，加大外壳的散热能力，延长润滑脂使用寿命等。球墨铸铁的外壳材料选择，大幅提高壳体的强度和性能，以及在高温/低温下的广泛应用。使用方形尾罩设计，控制丝杠不自转。加工设备和加工组装工艺，是高产品质量的保证，具有抗冲击能力强，高强度，低噪音，长寿命，体积小的特点。

模块化组合丰富了产品的组合变化，螺旋升降机可以直接与电机/减速电机/非标附件的任意组合，一体化设计，为客户提供上千种轻而易举的选择。

可以按照客户要求非标设计，如不锈钢壳体及丝杠螺旋升降机，多头丝杠，耐低温，耐高温等产品。

SJA worm gear screw elevator (SJA spiral elevator) is a basic lifting component that has many advantages, such as compact structure, small volume, light weight, wide power sources, convenient installation, no noise, multiple functions, multiple supporting forms, flexible use, high reliability, and long service life.
Characteristics of SJA screw elevator (SJA spiral elevator)
Thrust range: 0.5-30 tons
The travel can reach up to 8m, and the stability of the screw and the guiding mechanism need to be considered
-30% working hours, if the load rate is small, the working hours can be appropriately increased
The lifting speed is less than 1500mm/min (23mm/s), and in special cases, it can reach 46mm/s
- Efficiency less than 33%, with self-locking function, high deceleration ratio L1 definitely self-locking
- Precision positioning, with an additional anti backlash device, the accuracy can reach 0.05mm
- High synchronization, the same motor can drive multiple spiral elevators simultaneously, mechanical synchronization
- Can be equipped with encoder, limit switch, dust cover, safety nut, reducer, ordinary motor, servo motor, stainless steel material, etc
- Simple operation and maintenance, low noise
The square groove shell of the elevator increases the heat dissipation capacity of the shell and extends the service life of the lubricating grease. The selection of shell materials for ductile iron significantly improves the strength and performance of the shell, as well as its wide application at high/low temperatures. Using a square tail cover design to control the screw from rotating. Processing equipment and assembly technology are guarantees of high product quality, with strong impact resistance, high strength, low noise, long service life, and small size.
Modular combination enriches the variety of product combinations, and the spiral elevator can be directly combined with any combination of motor/deceleration motor/non-standard accessories, with integrated design, providing customers with thousands of easy choices.
We can design non-standard products according to customer requirements, such as stainless steel shells and screw elevators, multi head screws, low-temperature and high-temperature resistant products.
