Chain hoist from 198kg to 2500kg
LOAD TESTSLOAD TESTS
To test the functionality and settings of the brake and clutch it is necessary to carry out static and dynamic load
tests as defined below:
■
Static load test: apply a suspended load equal to 125% of the rated capacity to the non-powered hoist.
The test is deemed successful if the height of the suspended load does not change.
■
Dynamic load test: Apply a suspended load equal to 125% of the rated capacity to the hoist. Move the
suspended load for a short stretch. The test is deemed successful if the overload clutch does not
activate, and the brake is able of stopping the suspended load without slippage.
For both load tests, the anchoring point should be appropriately sized taking into account the actual loads in use.
WARNINGWARNING
Any interventions on the brake and overload clutch are prohibited. Only authorised EXE RISE personnelAny interventions on the brake and overload clutch are prohibited. Only authorised EXE RISE personnel
may perform maintenance and replacement operations to the brake and overload clutch.may perform maintenance and replacement operations to the brake and overload clutch.
7.1.47.1.4 STRAORDINARY INSPECTIONSTRAORDINARY INSPECTION
Inspection conducted exclusively by EXE TECHNOLOGY authorised personnel to ensure the maintenance of
appropriate safety conditions whenever exceptional events occur which may have detrimental consequences for
the safety of work equipment, such as repairs, modifications, accidents, natural phenomena or extended periods
of inactivity. The procedure for this inspection is analogous to that for “periodic inspections” in paragraph 7.1.3.
The results of the checks must be recorded in a logbook, kept and presented during surveillance checks.
7.1.57.1.5 QUARTERLY CHECK CHAINQUARTERLY CHECK CHAIN
Checks to highlight possible wear, kinks, deformations, cuts, corrosion, chemical damage, section shrinkage,
lengthening, with particular attention to the contact area between links, the contact areas with wheels and pinions,
as well as the attachment points to the chain ends fitted with pins. A useful reference for chain checks is UNI EN
818-7 standard. The results of the checks must be recorded in a logbook. The procedures for the checks are set
out in paragraph 7.2.2.

7.2.17.2.1 HOOK INSPECTIONHOOK INSPECTION
Chain hooks must not present cracks, permanent deformations or be damaged by corrosion and/or chemical
agents; otherwise they must be replaced (see section 8.1)
The maximum acceptable permanent deformation of the hook opening (A) as showed in figure 8.1 must be
less or equal to 5% of the normal value. The maximum permanent deformation due to torsion must be less
than 10° in relation to the plane of symmetry of the hook.
Any hook with deformations that exceed the above limits indicates overload and must be replaced.
The safety latch must open without excessive play, and snap back to the tip to its position when released.
The safety latch and its rotation pin must not be bent or damaged.
Inspect the other supporting parts, hook block screws and load pin for damage.
