CHECKLIST FOR ELEVATOR FUNCTION TEST AND LOAD TEST

CHECKLIST FOR ELEVATOR FUNCTION TEST AND LOAD TEST

1. Visual Inspection

A certified Inspector shall check and verify all documents and other pertinent papers of equipment to be load tested.

1. The structure shall be thoroughly Inspected and the rated capacity (SWL) should be verified.
2. The load capacity (SWL) of elevator shall be marked on the elevator and shall be visible in every door opening from ground floor to last floor level.
3. Ensure that working place Is cleared from unnecessary object.
4. The surroundings of the lifting equipment shall be barricaded and protected.

2. Mechanical Running Test

1. Mechanical function of the Interlocking and hatch should be easy and the hatch can be fully opened.
2. Mechanical function test for the hatch lock and trapdoor.

3. Functional Test

1. Ensure that all functions of emergency stop circuit and safety device limit switch must be guaranteed In accordance with the applicable wiring diagram.(such as: shaft pit, return control, landings, main switch cabinet, dummy plug external controls, emergency limit up/down over speed safety brake, roof hatch interlocking, trapdoor, trailing cable, and cabin doors).
2. Check signaling unit of ground station. (Horn, light and potential-free alarm contact)
3. Check correct operation of Return Control. This is used to return the (empty) car during poor weather conditions or following a malfunction.
4. Check correct operation of lighting. lights are located In the elevator car, on the roof of the car and in the underrun section. light in the car should still function even when the main switch is off. The emergency lighting in the car should turn on automatically when the main voltage is Interrupted. The lighting on the car roof only illuminates when the key switch for maintenance control is
   set to “MANUAL”.
5. Check elevator doors Interlocking safety lock. To ensure that the car door must not be able to be opened during movement and
   locked by the safety lock.
6. Check mechanical emergency unlocking of the car door. To ensure that in event breakdown of the main power supply, the locked car door must be able to be opened using a triangular key. leave the car door open and test if elevator will accept any driving command if the car door Is open. Elevator should not accept any driving command If the car door Is open.
7. Check landing door not to be opened during elevator operation.
8. Check landing door is to be opened by triangular key when car is in front of any landing. leave the landing door open and test If elevator will accept any driving command. Elevator should not accept any driving command if the landing door Is open.
9. Check electrical emergency unlocking of the car door. To ensure that In the event breakdown of the main power supply, the emergency unlocking of the car doors must be possible at enabled landing.
10. Check emergency power supply. To ensure that In the event breakdown of the main power supply emergency functions of the lift control are maintained by a UPS cable.
11. Check mechanical lowering brake. To ensure that in the event breakdown of main power supply, the lift brake can be released using the lower pedal Installed In the car and the car can descended to the next landing.
12. Check electrical lowering brake. To ensure that in the event breakdown of the main power supply, the button “Start emergency lower” can be used to automatically lower the car to the next landing.
    Test run. Drive in automatic mode to any landing or to base enclosure. The car door has to stop maximum 10mm higher or lower than level.
13. Limit Switches. If the hoist is working In automatic mode (normal operation} then the hoist starts from the reference limit switch and the levels get reached by using the encoder. If the hoist is working with the Installation control on the car top then hoist Is working in inching operation and stops the limit switch down or up.
    1. limit switch down: Drive down the hoist with control of the car roof. The car stops on the bottom cam and do not drive down ahead.
    2. Limit switch up: Drive up the hoist with control of the car roof. The car stops on the top cam and do not drive up ahead.
    3. Reference limit switch: Drive car in auto mode down to base enclosure. Car stops on correct height and reference limit switch is working.
    4. Emergency End: Drive to limit switch end or push the Limit switch. The hoist has to stop.
14. Proximity switches. The inductive switches release the safety relay for the door locking. Do the proximity switch test by driving to the base enclosure or any level. The sensors are working if the door gets released.

4. Load Test

4.1  Dynamic Drop Test of Safety Gear

1. Put weights into the cabin. First drop test will be executed with 125% of maximum payload.
2. Execute the drop test. Climb onto the roof of the car through the roof hatch. Rotate the key switch on the maintenance control to the position “OFF”.
   Remove the dummy plug from the plug connection. Connect the drop test control into the socket. Take the manual control out of the car and down to the base enclosure. After that, leave the car roof.
3. Press the up button until the car has reached a height of approx. 6m. Then, press the brake release buttons. The brake opens, the car drops down. The safety gear must stop the car after approx. 2-3m. If the car does not stop, immediately release buttons.
4. If drop test was successful, press the UP button, Car move out of the catch position. Press the down button and move the car to the bottom stop position. Disconnect the drop test control unit. Insert the dummy plug. Turn the key in the key witch of the maintenance control (car roof) to the position “operation”. Then check safety gear for damage. If no damage, reset the safety gear.
5. If drop test was not successful, press the DOWN button and move the car to bottom stop position. Switch off the machine at the main switch and secure against switching on. Immediately replace the safety gear. Operation of the machine Is prohibited until then.

4.2 Overload Protection

Overload switching at 110% of payload. Put weight into cabin. The overload alarm has to get activated at more than 110% of payload. Check the control unit if the overload alarm (red) is on.
