• Excellent Operativeness

The new control system which combines Inverter operation and contactor operation for the first time in the industry realises smooth operativeness and quick response of stop and speed reduction. In addition, low hoisting speed can be selected from 3 speed types. In the case of hoist with traversing inverter, high speed can be selected from 4 speed types  and   low  speed  can  be  selected from  2  speed  types.   In comparison with the conventional creep type, the setting range is wider.
 

• Improvement of maintenance

Since its structure part is the same as general purpose hoist, the number of parts decreased significantly compared with the conventional creep type. And the maintenance is easy as its control parts are made into one board.
 

• Effect of conservation of energy
As UR type does not use a regenerative resistor, it is more power saving compared to U type. The durability of its brake disk becomes about double in comparison with that of the conventional creep type.
 

• Excellent cost performance
The UR series is variable speed hoist very high in cost performance.

Speed setting
(Lifting/Lowering)

High speed: Fixed(Normal speed)
Low speed: select from 1/10,1/6,1/4
of high speed

High speed: Fixed (Normal speed)
Low speed: Fixed
(1/10 of  Normal speed)

Setting is possible at arbitrary speed with high speed, the low speed between 1/10
of normal speed - normal speed

 

Speed setting(Traversing)

High speed: select from 25, 20, 15, 10m/min
Low speed: select from 2.5, 5/min

High speed : Fixed
Low speed : Fixed
Speed ratio 1:1/4 or 1:1/5

Setting is possible at arbitrary speed with high speed, the low speed between 1/10
of normal speed - normal speed

Remarks
• High lowering is contactor operation, speed is 6m/min in 1t and 6.7m/min in 2t•2.8t for the power supply of 50Hz.
• Lifting low speed is set to 1/10 of high-speed at shipment.
• High speed traversing/low speed traversing is set to 25/2.5m/min at shipment.
Caution
• UR Series are not possible to use for the lift.
• When the winding creep is done, it is not possible to operate smoothly by the traversing resistance. Please contact us.
• We recommend the installation of the noise filler because it might mis-operate in the point where a lot of power supply noises exist
• Please contact us when you use the product in a lot of places such as the causticity gas and dust that are.
• Speed range of lifting and lowering in low speed is ±40% of the display value in the ratings load. The speed difference between much load end no load grows at the time of a low speed operating, too.
