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 1ton 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.

4. Advanced suction rotary motor brakeElectromagnetic brake system
           Suction rotary motor brake made of non-asbestors (brake linings) reduces maintenance times greatly and can precisely and effectively make the  hoist stop running, even when there is a lack of power.
           Generally speaking, only when alternating current/direct current brake is installed can  the brake work with power off and the hoist work with power on, thus the load  won’t fall due to the closed circuit of motor.
           Heavy duty design for reliabie operation. Direct acting for positive load holding and  spotting, Independent heavy-duty DC brakes of hoist motors are able to  eliminate heat rise and control the load securely.

7. Anti-phase relayPhase error relay
           The anti-phase relay device protects machine from damage when power connection is in wrong way.
           A  specially designed current-post, prevent motor from running at incorrect wire  connection, in other words, when the phase is incorrectly connected.
8. Overload clutchfriction  clutchSafety clutch(inside the hoist)
           Overload  clutch also called special over-rolling protection device  soaked in the oil prevents  the hoist extremely rolling up or being overloaded and ensures the life- span of hoist. As emergency overload happening, the protection clutch will function
           It  prevents damage to the hoist by automatically engaging in the event of an  excessive overload. When the overload clutch engages, the motor is allowed to  continue turning protecting both you and the hoist.
