Product Description

A.The features of Worm gear speed reducer Ratio 1:16

  1. The reducers have the following features because of using plane enveloping worm gear as compared with other kinds of worm transmissions: larger loading capactiy and compact dimension and higher efficiency and smoother and quieter functioning longer service life.
  2. In addition, the housings of these series reducers are made of high-strenghth aluminium alloy. So the reducers make the features of higher strength and lighter weight.
  3. It is recommended to utilize the viscosity VG320 synthetic worm gear oil (or synthetic gear oil) for lubrication. Once the environment temperature is higher than 30°C, it is recommended to utilize the viscosity VG460 synthetic worm gear oil(or synthetic gear oil) for lubrication. And allowed maximum working oil temperature is 100°C.

  1. The base-plate must be plane and stoutness and the base-plate must be screwed down and shock proof.
  2. The connecting shaft of prime mover, reducer and operation device must be coaxial installation.
  3. The diameter tolerance zone of input and output shaft is H6, the holes of fittings( such as couplings, belt-pully, sprocket wheel and so on) must properly mate the shaft, which prevents bearing from breakage because of over-loose mate.
  4. Drivers such as sprocker wheel and gear must be fitted close to bearings in order to reduce bending stress of hanging shaft.
  5. While assembling motor of WPD reducer, it is necessary that proper amount of butter applies to the warm shaft input hole and keyway, avoiding assembling too tightly and rusting after using for a long time.
  6. When ordering or using all kinds of WPD type, if the motor weight is bigger than the common,supporting set is required.

Manufacture ofELAMK tower cranebased in China, and we are specialized in providing types of construction lifting machinery , luffing, topless and hammer head tower crane, passenger hoist, suspend platform as well as its spare parts worldwide.











Max jib: 50-70 m

Capacity: 5-20 t

In the Topkit cranes a counter-jib and a hoist jib are connected to the cap through a tie rod, respectively. Compared to the Tower Crane without tower cap, its jibs boast smaller weight, simpler structure and better stability.

EMK models are the traditional tower cranes which are especially designed for large construction sites. Assembling is extremely fast and easy and the lifting, slewing and distribution mechanisms are strong, simple and reliable.
