Mayi Industries Hw Series Low Profile Lift Table Instruction Manual

HW Series Low Profile Lift Table

Product Information

The HW Series lift table is a hydraulic lifting device that is
designed to lift loads up to 1000kg. The lift table has a lowered
height of 200mm and can be raised to a maximum height of 200-300mm
depending on the model. The platform length is 1220mm and the
platform width is either 610mm or 1220mm depending on the model.
The lift table is powered by an AC motor with power output ranging
from 1.1KW to 2.2KW depending on the model.

Product Usage Instructions

Before using the lift table, it is important to read and
understand the instruction manual completely. Follow all safety
instructions strictly and check all safety devices before
operation. Ensure that there are no obstacles in the working area
and do not put foot or hand in scissors mechanism or through
frame.

Daily inspection is effective to find any malfunction or fault
on the lift table. Check all the terms of warning and caution,
scratches, bending or crack on the lift table, smooth movement of
the table, hydraulic oil leakage, vertical creep of the table, and
if all the bolts and nuts are firmly tightened. Do not use the lift
table if any malfunction or fault is found.

When loading the lift table, ensure that the load is distributed
evenly and not overloaded. Do not load partially or concentrically.
To lift the load, screw and loosen the emergency stop switch, push
the UP button and the power pack starts to work to lift the load.
Loosen the UP button and the power pack stops working. When
lowering the table, do not put foot or hand in scissors
mechanism.

Periodic service of the lift table is necessary to make it work
easily and have a prolonged service life. Refer to the recommended
table to service the lift table periodically. In case of any
trouble, screw two eyebolts into relevant screw-holes on the basis
lest the table lowers accidentally.

THANK YOU VERY MUCH FOR SELECTING OUR PRODUCT. THIS INSTRUCTION MANUAL DESCRIBES CORRECT OPERATING METHOD TO ENSURE PROLONGED SERVICE LIFE. PLEASE READ AND COMPLETELY UNDERSTAND THIS MANUAL BEFORE OPERATING THE LOW PROFILE LIFT TABLE. ALWAYS KEEP THIS MANUAL AT AN APPROPRIATE PLACE. IF THE MANUAL OR WARNING DECAL IS MISSING, PLEASE CONTACT WITH DEALER. Note: This Manual has been prepared for skilled and competent personal. It provides instructions for using the product correctly and parts list. This Manual cannot replace the professional skills and expertise of the user.
1. WARNING! If operating the lift table improperly, a person may be seriously injured. Therefore, operate properly according to the following instruction
. Read & thoroughly understand the Instruction Manual completely before using. Follow all safety instructions strictly. It is necessary to check all safety devices before operation. Make sure that there are no obstacles in the working area. Do not put foot or hand in scissors mechanism or through frame.
2

Screw the lifting eyes on the base frame before working on the lift table. Do not overload the lift table. Load should be distributed on the table according to relevant load distribution chart. Pay attention if local voltage and frequency is as same as the input specification of the lift table. Use the lift table on flat and solid ground. All the electrical connection and disconnection operations must be carried out by skilled and competent personal. While operation, it is forbidden to contact the moving parts of the lift table. While the lift table moving, it is forbidden to adjust or to move the load. It is forbidden to lift the load, which perhaps does harm to a person or other object. It is forbidden to operate the lift table while a person is under the table. Do not adjust the safety valve of hydraulic power pack. It is forbidden to operate the lift table even if there is small structure distortion. Do not use in an explosive or flammable place.
2. CAUTION! If operating the lift table improperly, a person may be injured. Therefore, operate properly according to the following instruction.
3

The lift table is a movable lifter designed to lift or lower rated load. Do not use it for other purpose. Do not allow a person to operate the lift table, who does not understand its operation. It is forbidden to change the lift table without manufacturer’s written admission. It is necessary to use the spare parts designated by manufacturer. Make sure to keep a distance between the table and ambient objects enough to operate the lift table safely. Keep the hydraulic system under clean and safe condition. The hydraulic power pack features an electric lowering control. The coils must be fed with the required voltage as described on those coils. The power supply voltage should not exceed ±10% of the rated required voltage. Always do maintenance and routine check while the lift table is unloaded. The lift table is not waterproof and should be used in a dry environment.
3. DAILY INSPECTION Daily inspection is effective to find the malfunction or fault on the lift table. Before operation, check the lift table according to the following points. CAUTION! Do not use the lift table if any malfunction or fault is found.
4

Check all the terms of WARNING and CAUTION. Check scratches, bending or crack on the lift table. Check smooth movement of the table. Check if there is any hydraulic oil leakage. Check the vertical creep of the table. Check if all the bolts and nuts are firmly tightened.
4. Operating the lift table LOADING
The maximum capacity of the lift table is 1000kg. Load should be distributed on the lift table equably. Lifting the Table
CAUTION! Do not overload the lift table.
Ensure the balance of loading. Do not load partially or concentrically.
Screw and loose emergency stop switch. Push the UP button and power pack starts to work to lift the load. Loose the UP button and power pack stops working.
LOWERING THE TABLE WARNING! Do not put foot or hand in scissors mechanism.
5

Push the DOWN button and the table will lower. Loose the DOWN button and the table will stop. NOTE The table is equipped with an aluminum guard to avoid accidental danger. If aluminum guard strikes an object while the table lowers, stop operation and check the lift table. After making sure no any abnormality, strike the UP button slightly and then the electric system will function as before. EMERGENCY STOP There are two methods of emergency stop as follows. Push down the emergency stop switch and the movement of table stops. Strike aluminum guard upward and the movement of table also stops. TRANSPORTATION If necessary, the lift table can be transported with attached ringbolts. Pay attention to the maximum capacity of lifting equipment to be used. Keep the ringbolts with reasonableness.
