Testing
Operational Tests
Prior to initial use,all new,altered or repaired winches shall
be tested to ensure proper operation.
1.
Operate winch in both directions with no load.
2. Check operation of free wheel and brake.
3. Check operation of limit switches and other safety
devices when provided.
4. Check all winch mounting bolts are secure.
Load test
Prior to initial use, all new, extensively repaired, or altered
winches shall be load tested by or under the direction of a
person trained in the operation and service of this winch and
a written report furnished confirming the rating of the
winch.
−
For air winches LS series.
The minimum load test for European countries are
according to the chart below.If not found below you should
use the tests recommended by the FEM.
The dynamic test shall be carried out with an overload
coefficient
ρ
1 = 1,2 i.e. with a load equal to 120% of the
safe working load. All motions shall be carefully operated
in turn, without checking speeds of temperature rises in the
motors.
the static test shall be carried out with an overload
coefficient
ρ
2 = 1,4 i.e. with a load equal to 140% of the
safe working load.The test must be carried out under still
conditions and consists in hoisting the safe working load to
a small distance above the ground and then adding the
required surplus without shock.
−
For air winches PS series.
The dynamic test shall be carried out with the nominal
line pull.
The static test shall be carried out with an overload
coefficient
ρ
2 = 1,4 i.e. with a load equal to 140% of the
safe working load.
