Hitachi Type Electric Wire Rope Hoist Single Girder Electric Cable hoist
Detailed description1. BRAKE WITH AUTOMATIC ADJUSTING DEVICE
This new Hitachi type Wire Rope Hoist is similar technology as Japanese hitachi--the brake is with automatic adjusting device. This brake is automatically adjusted in proportion to the amount of lining abrasion to render it maintenance-free, eliminating hazardous brake adjustment high above floor level. This device also automatically adjusts to the wear of its link mechanism, thus achieving automatic adjustment of the overall brake mechanism, which is an exceptional feature.
2.AUXILIARY BRAKING DEVICE
First developed by Hitachi in the industry then put into production for our hoist, this mechanism is employed to absorb shock during operation. Should the main brake fail to function or should the motor shaft break, this auxiliary braking device is actuated absolutely to prevent a load from dropping. In conjunction with the brake with automatic adjusting device, this auxiliary braking device constitutes a positive, double braking mechanism.
3. TOP HOISTING SPEED
To raise efficiency, hoisting speed is very important and this hoist perform very well in the speed, Further, a standard speed type is available to conform to individual customer requirements
3.DURABLE WIRE ROPE
A filler rope usable three times longer than point contact wire rope is adopted.
5. LOAD BLOCK FITTED WITH SAFETY LEVER
The load block is provided with a safety lever (to prevent rope from dislodging) in addition to a safety cover. Further, Large sheave diameter assures rope prolonged durability.
6.HOOK WITH PUNCH MARKS new IS PROVIDED
The punch marks are convenient for inspecting hook opening by only measuring the distance between them.
7. INTEGRATED PUSHBUTTON CABLE
The push button cable and protective wire are built into a single assembly so that there will be no longer a broken wire by hooking the protective wire. This design also assures ease of push button operation.
8. PLASTIC PUSHBUTTONS
The plastic push buttons are light and easy to use without the danger of electric shock.
9. MOTORIZED TROLLEY
Wear of l-beam and wheels is negligible. The hoist travels by guide rollers and flangeless wheels, remarkably reducing wear on the l-beam and wheels.
Since a brake is provided, travel by inertia is small, facilitating load positioning.
Standard headroom type and low headroom type can be used commonly.
10. CONTROL BOX
Double-limit switch when the load block has reached the upper limit, the control circuit of the electro-magnetic switch is turned OFF, halting the operation. Should the circuit be short-circuited and the load block be moved further upward, the motor main circuit is cut OFF, stopping the hoist.
Reverse Phase-prevention device When reverse phase occurs, the motor main circuit is cut OFF, preventing accidents due to mis-wiring.
11. MOTOR
Hoisting motor is provided with a thermal protector which senses the heat of the motor coil and functions to protect the motor from burning damages caused by over work.

Highly Reliable Braking SystemThe hoist detects the amount of lining abrasion. The brake is equipped with an automatic adjusting device to apply brake torque in proportion to the amount of lining abrasion.
Hoisting Motor with a Thermal Protector.
The hoisting motor automatically stops when sensing the heat of the motor coil in order to protect the motor from burning damage caused by heat due to overwork.
Efficient Maintenance is PossibleThe starting time counter in the control box facilitates checking of the lifetime of consumable parts.
The gear inspection window in the control box allows visual checks of the condition of the gear teeth surface and lubrication to some degree.
The punch mark on the hook indicates the reference point for the hook inspection of deformation.
The inspection of the rope end is easy.
