ELECTRIC WIRE ROPE HOIST
XM SERIES
3. INSTALLATION INSTRUCTIONS
3.11.2 TROLLEY TRAVEL LIMIT SWITCH
Perform the connection to the main power line.
Do not interfere with the internal connections
of the trolley/hoist or the keypad.
Pressing the push buttons "right-left", run the
trolley along the whole length of the rail and
check that it stops correctly.
Check the proper position of the limit switch
stopper on the trolley, in order to ensure
adequate overrun room and avoid collisions
between the trolley and the fixed stopper.
3.11.3 BRAKE RELEASE
In "jog" mode, check the brake disk detaches
from the brake pad, thus freely rotating without
rubbing.
3.11.4 NOISE LEVEL
Verify the absence of abnormal noise during
lifting and travel, such as: squeaks, cyclic
noises, abnormal vibrations, etc.
The noise level of the hoist, even at full load,
must always be less than 85 dbA and constant.

3.12 LOAD TESTS
3.12.1 DYNAMIC TEST
Provide adequate weights for load testing
as follows: rated capacity x 1.1 and proper
slinging and lifting equipment.
Sling the load taking care to position the hook
vertically above the load itself, to avoid oblique
pulls.
Tension the slings slowly, avoiding jerks.
Tension the slings using the "slow" speed, if
available
Slowly lift the load and make sure it happens
smoothly, without abnormal noise levels bends
or structural settlements.
Repeat the test at maximum speed, carrying
out the previous check.
Check the "up and down" emergency limit
switches are properly working.
Check the brake is working properly, making
sure the mass is stopped within an adequate
time and that there is no abnormal slipping of
the load when the button is released.
Perform the same checks on horizontal
travel operation, without lifting the load at the
maximum height (lift it 1 metre
from the floor).
Operate first at slow speed, if available, and
then at maximum speed.
Check the trolley for smooth running on the
beam and make sure there are no abnormal
noise or structural settlements.
