Features
Hitachi Hoists Features a lot of Mechanisms for Safety and Easy Maintenance. User-friendliness and Reliability are Further Improved
Hitachi Original High Reliability Brake System
A brake with automatic adjusting device is adopted, and the brake is automatically adjusted in proportion to the amount of lining abrasion. Dual system of the main brake and the auxiliary brake is adopted.
Motor with Self-protective device
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.
Effective Maintenance is possible
Effective Maintenance is Possible
The counter for memorizing starting times makes easy to check lifetime of consumable parts.
Inspection Window for Gears makes possible to check conditions of the gear and lubricant.
Punch Mark shows the reference point of hook inspection.
Inspection of the Rope End is easy.
Hitachi Rope Hoist V Series is composed of reasonable system that Brake, Motor, Drum, Reduction Gear, Auxiliary Brake are unitized.
(1) Motorized TrolleyNEW
Long Life Wheel
The hoist travels by guide rollers and flangeless wheels remarkably reduce the wear of I-beam and wheels. Positioning is facilitated by a brake provided and small travel inertia. Brake torque can be adjusted, also. Besides the standard type and the low headroom type, wheels of the double rail type from two to five tons are quenched, and thus the lifetime is more than 2.5 times longer than that of previous hoists.
Self-adjusting of Center Core (Double rail type hoist)
By the Self-adjusting of Center Core, the wheels can closely follow the rails
(2) Motorized Trolley
A grease lubrication system is adopted. The hoist is greased prior to shipment and requires no grease replenishment during operation, ensuring a long period of utilization. The innovative building block system facilitates maintenance and checking.
(3) Auxiliary Brake Unit
A grease lubrication system is adopted. The hoist is greased prior to shipment and requires no grease replenishment during operation, ensuring a long period of utilization. The innovative building block system facilitates maintenance and checking.
Auxiliary Brake Unit
USA PAT No.4216848
(4) Steel Drum and SheaveNEW
Life of the drum and the sheave is about three times longer than previous ones, since the groove of them are processed by special press method.
(5) Inspection Window for GearsNEW
It is possible to check the condition of the gear teeth surface and lubrication with eyes. Inspection accuracy will be increased.
(6) Control BoxNEW
Counter for Memorizing Starting Times
The counter which indicates the total starting times of hoisting and lowering is useful for maintenance of the consumable parts like electromagnetic contactors, wire rope and brake solenoid, etc.
Electro-magnetic Switch with Mechanical Interlock
Erroneous operation can be prevented.
Double-limit Switch
When the load block has reached the upper limit, the control circuit of the electro-magnetic switch is turned off and the operation is stopped. Should the circuit be short-circuited and the load block be moved further upward, the motor main circuit is cut off.
Clamp Method
Clamp method of the control box cover facilitates opening and closing.
(7) Motor Unit
Each hoist is equipped with a motor which provides an optimal starting torque for the hoist. Employing cooling fans and large-capacity ball bearings, the motor can withstand severe operating conditions. 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.
(8) Brake Unit
The brake is equipped with automatic adjusting device, and is automatically adjusted in proportion to the amount of lining abrasion. Adjustment of the brake will not be required.
Brake Unit with Automatic Adjusting Device
USA PAT No.3908802 Germany PAT No.2354044
Reduction in Size and WeightNEW
K size, from road surface of the traveling rail to the top surface of the double rail hoist, is reduced by 20% and weight is reduced by 10%, and thus installation and operability are improved.
Thick Wire Rope
The wire rope features a long life.
Rope EndNEW
Inspection of the Rope End has been easy.
HookNEW
Punch Mark
Punch Mark shows the reference point of hook inspection.
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.
Integrated Pushbutton CableNEW
The pushbutton cable and protective wire are built into a single assembly so that there will no longer be a broken wire by hooking the protective wire. This design also assures ease of pushbutton operation.
User-friendly Pushbutton
The push button is totally enclosed type and is made of plastic.
It is light and easy to use without the danger of electric shock.
Brake Unit
The brake is equipped with automatic adjusting device, and is automatically adjusted in proportion to the amount of lining abrasion. Adjustment of the brake will not be required.
