MITSUBISHI HOIST

1. Traverse Brakes with Adjustable Torque
DC voltage magnetic disc brakes provide easy electrical control of the traverse motor. The brake torque can be adjusted to provide the ideal level of inertia for the particular application.
2. Control Box with Overload Prevention System.
A microprocessor system automatically detects overloads to ensure total safety. For ease of maintenance, the cover can be opened or secured by means of one-touch catch clips.
( Note : Power conditions in certain parts of the world mean that in some causes units must be shipped without this circuit )
3. DC Electromagnetic Brakes with Auto – Adjusting Mechanism ( Not exceeding 5ton )
These DC disc brakes are electromagnetically operated and will provide years of trouble – free service. the core gap is automatically adjusted according to the degree of friction on the brake surface to ensure a stable braking action.
4. Hoist Motor
This high–resistance die-cast motor combines a low starting current with a high starting torque. There is on initial buidup of heatand inching operations are easy.
5. 2-Step Hoist-Limiting Switch
The first step cuts off the hoist control circuit. The second shuts off the main power supply circuit under abnormal conditions, such as reverse-phase connection, reverse winding of fused connections.
6. Hook Block with Safety Cover
The entire assembly is enclosed for added safety.
7. Totally Enclosed Traverse Gear Assembly ( More than 7.5t monorail type and 7.5t low-head type are with dustproof cover)
The grease-lubricated tooth-gear system is fully enclosed to shut out harmful dust and prevent cog and shaft wear.
8. Side Plate for Traverse
The connection between the wheelshaft and the side plate is based on newly developed technology and provides total load security.
11. Simplified Hoist Gear System
( Not exceeding 3ton)

A simple 2-stage reduction system has been used for even quieter hoist operation.
12. Protective Construction for Drip-proof
13. Drip-proof Push-Button Switches
Switches are enclosed in a drip-proof plastic case for added protection against electric shock.
10. Steel Frame
Strength and reliability have been further enhanced by means if a design based on sophisticated mechanical analysis techniques.
9. Flangeless Wheels and Guide Rollers
( Not exceeding 3ton )
Friction between the l-beam and wheels has been mini – mized to ensure smooth traverse. The guide rollers are locat-ed on the outside of the side plate for easy maintenance and inspection
  Hoist Type (Shapes)
Monorail Type

Low-head Type

Double rail Type

Motor Operated Traversing Hoist
This hoist travels in parallel to the traverse rail by motor driven trolley. (This type of hoist is the most widely used)

Motor Operated Traversing Hoist
When this type of hoist performs hoisting to the upper limit, the distance between the bottom surface of the rail and the center of the hook becomes very short compared with Monorail Type. (Therefore, this type is very useful for use in a place with a small height of ceiling)

Motor Operated Traversing Hoist
This hoist travels on the 2 rails of the hoist type overhead crane in the traverse direction. (Since its stability is extremely high, in particular, this type is often used for a large capacity.)

Suspended Type

Frame mounted Type

 

This hoist is fixed at the ceiling and used only for lifting and lowering cargo.

This hoist is fixed on tha pedestal and used only for lifting and lowering cargo. (This hoist is usually used for the same application as suspended type as well as the substitution for a winch.

  Introduction of Products

HOIST


S Type
(1/2-60t)

For high frequency use S type series is heavy-duty type hoists for applications involving high frequency operations. Its hoisting speed and the duty class is the highest available. For more safety, a microprocessor control   circuit   which   auto-matically Prevents overloading is installed.


U2, HU2 Type
(1/2-60t)

Mitsubishi original inverter specially developed for hoist has realized the miniaturization and versatility. Functions, which detect the hook position and change to higher hoisting speed when zero load is detected, offer high level of operation efficiency.

M Type
(5t·10t)

For medium frequency use M Type series has been developed based on the next generation concept.
It has been designed for optimizing price and performance.


UR Type
(1-2.8(3)t)

UR Type series is produced by utilizing the power electronics technology accumulated by MITSUBISHI ELECTRIC, and has new variable speed type. It is popular for excellent operation.


R Type
(1-2.8(3)t)

For medium frequency use R Type series is structurally simple and economical with real capability. It is provided with one class higher capability and both power and worthy of its real capability and economical efficiency.


U-X • S-X Type
(1/2-60t)

Inverter Explosion-Proof Type  (U-X Type) Only 200V  class is available U-X Type series is the first lnverter Explosion-Proof Type in the industry. Explosion-Proof Type (S-X Type) Hoists used in places where explosive gas or  steam  exist  must   pass  the Explosion-Protection Examination. Explosive grade d2 and Ignition degree 4 grade are available.


  The selection of the model
At first, select by purpose of use, use condition, frequency of use and decide concrete model by capacity, lift, shape(Suspended Type, Frame mounted Type, with traversing) and hoisting speed next.

    1) AIIowable freqency of use
    Select the model by the start number of times (the number of times of the up and down operation of the push button), percentage of duty cycle. (Please refer to the hoist applications and seledtion diagram of P3.)

    2) Capacity
    S series, U2 series : 1/2-60t, HU2 series : 10t - 60t R series, UR series : 1t - 2.8(3)t , M series : 5t and 10t


    3) Lift

    We have Low lift type and High lift type. As for the low lift, 6m (more than 5t, 8m), the high lift is 12m. Most models make both high lift and low lift. *M Type has only 12M.


    4) Shape
    Suspended Type, Frame mounted Type, Monorail Type, Low-head Type, Double rail Type *There is some hoist which we don't produce by a model, capacity. (Please refer to production overview of P6.)
