Brake jamming
lf a hoist, which is under load, is suddenly relieved of load pressure, e.g. by lifting off the load
or when pulling down walls, and lowering has not been initiated first, the brake will remain
locked. The brake will also lock if the load hook with the bottom block is pulled too tightly
against the housing.
Releasing the jammed brake

lf the brake is jammed on extremely tight, it can be released by striking the hand lever.
Yale overload protection device (optional)
The overload protection device is set to approx. 25% (±15%) overload. Its adjustment must
only be carried out by a competent person.

NSPECTION
ERVICE
EPAIR
According to national and international accident prevention and safety regulations hoisting
equipment must be inspected:
• in accordance with the risk assessment of the operating company
• prior to initial operation
• before the unit is put into service again following a shut down
• after substantial changes
• however, at least once per year, by a competent person.
ATTENTION: Actual operating conditions (e.g. operation in galvanizing facilities) can
dictate shorter inspection intervals.
Repair work may only be carried out by a specialist workshop that uses original Yale spare
parts. The inspection (mainly consisting of a visual inspection and a function check) must
determine that all safety devices are complete and fully operational and cover the condition of
the unit, suspension, equipment and supporting structure with regard to damage, wear,
corrosion or any other alterations.
