Features

Assembly and disassembly are easy.
Maintenance and serviceability are improved.

(1) Inspection Window for Gears

It is possible to check the condition of the gear teeth surface and lubrication with eyes.
Inspection accuracy will be increased.

(2) Reduction Gear 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.

(3) Auxiliary Brake Unit

Should the braking force of the main braking system fails or the motor shaft breaks, the newly developed auxiliary brake prevents the load from dropping. In conjunction with the brake with automatic adjusting device, this auxiliary braking device constitutes a positive, double-braking mechanism.

USA PAT No.4216848

(4) Steel Drum and SheaveNEW

Life of the drum for 2 falls and 4 falls (2 ton and 3 ton), and the sheave is about three times longer than conventional company products, since the groove of them are processed by special press method.

(5) 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.

(6) Motor Unit

Each hoist is equipped with a motor which provides an optimal starting torque for the hoist and B class insulation. 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.

(7) 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.

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 Cable

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.
