Service and inspections may only be carried out by a competent person.
The inspection must determine that all safety devices are present and fully operational and covers the condition of the hoist, lifting gear,
accessories and supporting constructions.
The service intervals and inspections noted are for normal working conditions. Adverse working conditions, e. g. heat or chemical
environments, can dictate shorter periods.
• Yaletrac Mini electric winches are classified according to FEM/ISO in the mechanism group 1Bm/M3. This results in the theoretical
duration of use of 400 full-load hours.
This is equivalent to 10 years under normal operating conditions. After this period the hoist requires a general overhaul by the
manufacturer or by a specialist.
Attention: Maintenance work requires subsequent function testing with nominal load.
Daily Checks
• Visually check the pendant control switch and all cable for damage.
• Check the proper fastening of the rope winches to the supporting structure.
• Function check of the brakes (incl. triggering the EMERGENCY STOP button)
• Function check of the limit switches
• Function check of all installed safety devices
Regular Inspections, Service And Testing
According to the existing national/international accident prevention or safety specifications, lifting units must be checked
• At least once per year by a competent person
• According to the risk assessment of the operating company,
• Before the initial start-up,
• Before restart following a shutdown
• After basic alterations. The concerned use 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.
Initial operation and recurring inspections must be documented (e.g. in the CMCO works certificate of compliance).
If required by the trade association, the results of inspections and appropriate repairs must be verified.
If the hoist (from 1 t lifting weight) is fitted on or in a trolley, or if the hoist is used to move a lifted load in one or several directions, the
installation is considered to be a crane and the further inspections must be carried out, in accordance with DGUV Vorschrift 54 Cranes.
Paint damage should be touched up in order to avoid corrosion. All joints and sliding surfaces should be slightly lubricated. In case of
heavy contamination, the unit must be cleaned.
ATTENTION! Power supply must be disconnected while inspecting the device, unless the type of the examination excludes
this!
Daily checks by the regulator
• Check the proper fastening of the Yale continuous winch to the suspension.
• Check the working of the UP and DOWN as well as the EMERGENCY STOP buttons.
• Check the working of the upper EMERGENCY limit switches: If the trigger is pressed manually during the upward movement of the
unit, the load should stop immediately.
Maintenance of the wire rope
ATTENTION: Always wear protection gloves for handling wire ropes.
Only original Yale wire ropes in good condition shall be used.
The Yale continuous winches are specially designed for this wire rope. For this reason only ropes that have been explicitly approved by
the manufacturer for these units shall be used.
A worn wire rope must be replaced only by a wire rope of the same type, dimensions and quality.
