System Maintenance 9
Section 5: System Maintenance
5.1 Preventative Maintenance
In order to maintain a safe and efficient hoist system, it is necessary to implement a regular
and continual preventative maintenance program. Listed below are the critical areas of the
hoist system that need consistent review, inspection, and/or correction. This list is a guideline
to assist in establishing a maintenance program, but cannot replace ongoing visual inspection
by operating personnel. Daktronics should be contacted immediately if any irregularities are
found.
To prevent accidents, injuries, or failures Daktronics recommends a professional inspection at
least once each year. Vortek offers the most thorough preventative maintenance program in
the motorized rigging industry. This
program will be offered to facility management after your hoist installation is complete.
The system should be run for a minimum of 2 minutes every month in order to ensure
proper lubrication. Neglect may result in damage to the rigging system.
Periodic inspections when operating the hoist should include the following:
SWAGED CONNECTORS: Look for wire rope damage where the swaged
connector contacts the cable. Check for broken cable strands.
TURNBUCKLES: Check that cotterpins and pin nuts, or bolts and nuts are in place and
secure. Check that pins in jaws are not bent. If bent pins are found, the set has been over-
loaded and should be inspected professionally for more serious damage.
WIRE ROPE: Check for worn areas, kinks, broken wire strands, or any deformation. Examine
cable runs for any obstructions or sources of abrasion. Excessive dirt will shorten the life of the
cable. If cable has begun to rust it must be replaced immediately.
REDUCERS: Check for visible oil leaks. If any noticeable oil leaks occur, please call
Daktronics immediately.
BRAKEMOTORS: Listen for unusual noises such as squeaking or grinding which may
indicate the need for lubrication or brake adjustments. Call a Daktronics service representative
for any brakemotor service (585) 924-5000.
ELECTRICAL: Check to ensure that electrical flex connections are secure and that no wires or
connections have been pulled apart. WITH ALL POWER OFF, open starter cabinets and verify
that wires are clean and orderly. Check that all cabinet doors are properly secured prior to
energizing.
HOIST ASSEMBLY: Check that all cables are smoothly wrapped on drum. Cables should
not climb over adjacent wraps. If excessive dirt is accumulating on drum, steps must be taken
to remove and prevent this accumulation.
NOTE: Not all items discussed in this maintenance manual may be required for every
installation. Contact Daktronics for specific information.
