PROCEDURE FOR THE ADJUSTMENT AND TESTING OF THE LIFT
• ADJUSTMENT OF THE MECHANICAL ALIGNMENT OF THE CARRIAGES
1) press the up button and check the correct direction of rotation of the motor (the carriages must go up)
otherwise change two phases on the terminal board.
2) lift the carriages to about 50 cm and measure the height. If there is a difference, tension the sync ropes.
•
CHECK THE DEVICE AND SAFETY LIMIT SWITCH FOR CHAIN TENSIONING
•
CHECK THE CORRECT OPERATION OF THE ELECTROMAGNETS, IF NECESSARY ADJUST THEM
AGAIN
•
CHECK CORRECT LUBRICATION OF MOVING PARTS
•
CHECK THAT THE RELIEF VALVE IN THE CONTROL UNIT DISCHARGES WITH HIGH MECHANICAL
LIMIT SWITCH
•
CHECK THAT THE ARM LOCK SAFETY RACKS ENGAGE IN THE VARIOUS POSITIONS (ARM FULLY
OPEN AND ARM FULLY CLOSED)
Once the main functional tests have been successfully completed (complete high/low stroke, no leaks in the hydraulic circuit, correct
operation of the safety devices, correct adjustment of the synchronisation cable tension, etc.), install the necessary parts (e.g.
installation of the protective cover on the ground between the two columns, etc.) to carry out another functional test with the load
(machine lifting).
Caution: under certain limit load conditions, if stationary (safety) it may be necessary to operate the down control a
second time to correctly complete the "pre-lifting/release safety/descent" cycle.
In this case, adjust/increase the rise time of the mechanical safety devices by means of the timer
• Complete the installation of the machine
o Mount the various protective covers (e.g. slave column electromagnet, base,
etc.)
o Mount column frontal protection (curtain)
o Etc.
• Check that the machine is complete with the documentation usually supplied (e.g.
User Manual, etc.)
• Check the tightness of the locking plugs, tighten them if necessary.
When everything has been verified, checked, proceed with the demonstration and training of users
