Inspection; Maintenance - Pacific Hoists U-MEGA Series Operations Manual & Parts List

V. INSPECTION
To maintain continuous and satisfactory operation, a regular periodic inspection procedure
must be initiated so that worn or damaged parts can be replaced before they become unsafe.
The frequency of inspection must be determined by the individual application.
The following list gives an inspection procedure for normal usage under normal conditions.
When the unit is subjected to heavy usage or duty, moist or other adverse atmospheric
conditions, shorter time periods must be assigned. Inspection must be made of all parts for
unusual wear, corrosion or damage in addition to those specifically mentioned in the
succeeding list.
It is suggested that the unit be inspected monthly for wear damage and corrosion effects to all
parts with particular attention to the following:
1. Tightness of all fasteners.
2. Contactor and control station for burnt or pitted contacts and loose or corroded terminals.
3. Cables and leads for broken wires, loose or corroded terminals and damaged insulation.
4. Terminal board for loose or corroded connections.

8. Collector or power supply system for damage, wear corrosion and proper operation.
VI. MAINTENANCE
The following three steps are recommended for maintenance:
1. Once a month lubricate track wheel gear and pinion with grease or graphite grease.
2. Motor reducing gearbox uses planetary gear lubricated with cosmo No. 3 grease (Equivalent
to: Shell Unedo 3, Exxon Eastan 3, Mobil Cup Grease 3) for good maintenance. It is highly
recommended that the motor gearbox grease should be changed after 100 hours of
operation, then every 6 months or 2500 hours of normal service. Whichever comes first, the
grease needs to be changed as well.
