INTRODUCTIONS

(N)RM Electric Chain Hoists are new KITO type electric chain hoists which  further builds upon previous RM series, To ensure safety, it adds overload  clutch inside (built in friction clutch/safety clutch/ slip clutch/ overload  limit) rather than Overload Protector outside the hoist (optional for RM series), with the upper-lower limit switch (Our limit switch do  not need adjustment since it is automatical adjust), it is more safe and reliable than RM series.

Uniquely-designed push button control on the basis of ergonomics, enhanced durability of load  chain, improved ease of maintenance as well as support for the environment achieve higher safety and working efficiency, this series, therefore, provide long-period stable operation, which is essential for improving production efficiency. Due to further improved durability, the increased product service  life and reduced running costs have resulted in minimizing the lifetime cost.

Stage chain hoist is a special used stage lifting equipment and theater equipment which ensures safe and accurate positioning for speakers, lighting systems, stage facilities, scenery, etc. Electric stage chain hoist have single and double chain, usually max. lifting capacity is 1 ton based on single phase; If power supply is three phase, the stage chain hoist can be customized design according to clients’ demands. Normally, Its surface is painted yellow color, 36V control voltage, the bidirectional and all-weather use and design, equipped with adjustable screw type limit switch.

Stage special electric hoist also called stage rigging or Stage Lifting Hoist is in strict accordance with the tour, roving exhibitions request design production, surface treatment, bright black lacquer abiding; 380 volts control circuit heat treatment of the forming roller chain plate steel guide to operate, easy maintenance, With positive and negative two-way and 24-hour use designed accords with 30,000 tons of lifting equipped with adjustable screw limit switches, reliable performance higher, Hoisting height can reach 38 meters minimum 161 safety design coefficient chain galvanized processing, is not easy to rust lubricating grease installed in gear box, prevent oil droplets penetration to the stage on the motor seal in the aluminum gourd cylindrical shell, within the rims permanent protect motor suits with various controller and circuit connected distributor.

Our Upside-down (theatrical/stage) type was designed by using the latest technology for handling theatrical and stage equipment. These high quality, low-headroom, full-featured hoists provide reliable performance for use in theaters, concert halls, arenas and studios, Stage electric hoist is specifically for large-scal  performances, lighting hangers, loudspeaker sets, large set design, also applies to other temporary occasions such as lifting mobile advertising  legislation licensing installation and small construction sites.... to be positioned with precision and total safety. 
The (N)RM Electric Chain Hoist can improve efficiency in the most demanding of work environments and satisfy even the most demanding of customers.
This model Electric chain hoists are widely used in factories, workshops, warehouses, mines, Bridges, construction and other occasions for materials hoisting, equipment installation, etc. Especially are suitable for high-rise building construction and welding storage tank with a number of crane.
