Operation/Inspection procedure

This section describes the general handling of LIFT MASTER.

For details, please refer to the instruction manual included with the product.

Operation

  • ・Always use LIFT MASTER within the allowable load, the allowable overhung load, and the allowable lifting speed.
    Exceeding any of these ranges may damage the lifter.
  • ・Under no circumstances should the lifter be used out of nominal stroke, even when operating with no load. Exceeding the nominal stroke range may damage the lifter. Do not subject the lifter to sudden impacts under any circumstances.
  • ・Ensure that foreign substances such as dust and hot chips do not attach to or enter the screw or tor any other movable components or detection units. These substances will accelerate wear in the unit and may lead to serious trouble such as reduced screw life and damage to moving parts. Take appropriate measures to prevent foreign particles from entering the Lift Master.
    In addition, use a safety fence around the Lift Master to prevent entry into the space under the lifting materials.
  • ・Be sure to design the sequence circuit so that the holding brake of the motor operates to prevent the load from dropping when operation is stopped.
  • ・Never use the lifter with contact stop. Press stop may cause critical damage to the Lift Masters.
  • ・Lift Master should only be used in situations where compressive loads are applied.
⚠
Warning
  • ・Some areas of the lifter may become hot. Keep hands or any other part of the body from coming in contact with such areas.Failure to do so may result in burn injuries.
  • ・Stop operation immediately if an error occurs.Failure to do so may result in electrical shock, injury or fire.

Maintenance/Inspection

1. Remove the cover

Remove the right cover when changing the positions of the upper and lower limit sensors and lubricating screw shaft. Remove the left cover when lubricating the guide.

Remove the mounting screw (cross-shaped recessed rounded head screws; M6 × 12) before removing the cover.

※The diagram below is for reference only. Please refer to the delivery diagram for the actual dimensions.

Remove the cover

2. Greasing

(Threaded portion )

Move to its maximum stroke, wipe off the old grease, and then apply it directly to the screw shaft with a grease gun or brush.

(Guide )

Apply grease using the grease nipple.

Apply sufficient new grease until the old grease is drained.

After lubricating, run in the chain and remove any excess grease before starting operation.

3. Maintenance / inspection of three-phase motor (hypoid motor)

For maintenance / inspection of the hypoid motor, please refer to the attached hypoid motor instruction manual.

Work procedure

  • (1) Be sure to turn off the power before starting this work.
  • (2) Disconnect the Lift Master main unit and the customer's equipment so that no load is applied to the Lift Master main unit. In such cases, prevent the Lift Master from falling by lifting the base plate.
  • (3) Loosen the four bolts securing the hypoid motor.
    At this time, if all four bolts are removed, the hypoid motor may fall out downwards, so leave one of them loosened to prevent the motor from falling out.
  • (4) Remove all bolts while holding the hypoid motor to prevent it from falling out.
  • (5) Pull out the hypoid motor downward.
  • (6) Assemble the hypoid motor by aligning the key phase of the hypoid motor hollow shaft with the key phase of the screw shaft end.
    (Reassemble in the reverse order of disassembly. )

4. Reducer with servo motor, servo motor maintenance and inspection

For maintenance and inspection of the reducer, please refer to the attached instruction manual. For servo motors, please refer to the manufacturer's instruction manual.

4-1. Reducer replacement method

  • (1) Be sure to turn off the power before starting this work.
  • (2) Disconnect the Lift Master main unit and the customer's equipment so that no load is applied to the Lift Master main unit.
    In such cases, prevent the Lift Master from falling by lifting the base plate.
  • (3) Loosen the four bolts securing the reducer.
    At this time, if all four bolts are removed, the reducer may fall out downwards, so leave one of them loosened to prevent the reducer from falling out.
  • (4) Remove all bolts while holding the reducer to prevent it from falling out.
  • (5) Pull out the reducer downward.
  • (6) Assemble the reducer by aligning the key phase of the reducer hollow shaft with the key phase of the screw shaft end.
    (Reassemble in the reverse order of disassembly. )

4-2. Servo motor replacement method

  • (1) Be sure to turn off the power before starting this work.
  • (2) Disconnect the Lift Master main unit and the customer's equipment so that no load is applied to the Lift Master main unit.
    In such cases, prevent the Lift Master from falling by lifting the base plate.
  • (3) Loosen and remove the four bolts securing the servo motor.
  • (4) Pull out the servo motor in the direction of the arrow.
  • (5) Make sure that the key is attached to the servo motor, align it with the keyway on the reducer side, and assemble the servo motor.
    (Reassemble in the reverse order of disassembly. )
