升降機的方形凹槽殼體，加大外殼的散熱能力，延長潤滑脂使用壽命等。球墨鑄鐵的外殼材料選擇，大幅提高殼體的強度和性能，以及在高溫/低溫下的廣泛應(yīng)用。使用方形尾罩設(shè)計，控制絲杠不自轉(zhuǎn)。加工設(shè)備和加工組裝工藝，是高產(chǎn)品質(zhì)量的保證，具有抗沖擊能力強，高強度，低噪音，長壽命，體積小的特點。

模塊化組合豐富了產(chǎn)品的組合變化，螺旋升降機可以直接與電機/減速電機/非標附件的任意組合，一體化設(shè)計，為客戶提供上千種輕而易舉的選擇。

可以按照客戶要求非標設(shè)計，如不銹鋼殼體及絲杠螺旋升降機，多頭絲杠，耐低溫，耐高溫等產(chǎn)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.
