Section 4: Testing Required
Once all the wiring connections are confirmed, the mechanical assembly is complete and the lift
is secured you can proceed with testing to prove that all systems and main safety functions are
4.1 Weight Testing
active and functional.
Every lift should be weight tested once the installation for mechanical and electrical items is
complete to ensure that the lift is operating correctly. All lifts are tested at the factory but they
are then disassembled and shipped to sites across North America.
The lift capacity may vary but this will be noted on the lift serial number label as well as other
documentation.
Weight testing may comprise 2 elements:
1. Maximum Lifting capacity – you apply full load to the lift in the center of the center of the
platform and the lift should operate in the upward direction. Current draw by the machine
should be less than 13A.
2. Overload testing – North American Safety code requires that with 125% the lift does not
move in the downward direction unintentionally. To test this, raise the lift roughly 12 in
and apply 125% of rated working load and check that the lift does not move in the
downward direction unintentionally. The lift is not required to lift 125% of working load.
Interlocks and all other safety devices should be tested to ensure they
work in the appropriate manner. If you are uncertain whether they are
operating correctly, please consult with your RAM dealer or call RAM's
technical support team.
