Hitachi electric chain and wire rope hoists are manufactured at par with industry-best standards, and deliver high productivity and efficiency. Hitachi’s reputation for excellence in design quality, reliability and performance has made the brand a market leader the world over.
1. BRAKE WITH AUTOMATIC ADJUSTING DEVICE
Developed by Hitachi as a “first” in the industry, this mechanism is em-ployed 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, dou ble-braking mechanism.3. TOP HOISTING SPEED
To raise efficiency, hoisting speed is the fastest in Japan. Further, a standard speed type is available to conform to individual customer requirements.4. 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 safetV cover. Further, Iarge sheave dia-meter assures rope prolonged dura-bility.
6. HOOK WITH PUNCH MARKS IS PROVIDED
The punch marks are convenient for inspection of hook opening bv only measuring the distance be-tween them.
7. INTEGRATED PUSHBUTTON CABLE
The pushbutton cable and protec-tive 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.
8. PLASTIC PUSHBUTTONS
The plastic pushbuttons are light and easy to use without the danger of electric shock.
9. MOTORIZED TROLLEY
Wear of l-beam and wheels is negli-gible. The hoist travels by guide rollers and flangeless wheels, re-markably 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 lowheadroom type can be used com-monly.
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 miswiring.
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.
