General. Following the designated lubrication procedures is important in ensuring maximum crane
lifetime and utilization. The procedures and lubrication charts in this section include information on the types of
lubricants used, the location of the lubrication points, the frequency of lubrication, and other information.
The service intervals specified are for normal operation where moderate temperature, humidity, and
atmospheric conditions prevail. In areas of extreme conditions, the service periods and lubrication specifications should
be altered to meet existing conditions. For information on extreme condition lubrication, contact your local service
representative or Grove Customer Services, Chambersburg, Pennsylvania.
CAUTION
Chassis grease lubricants must not be applied with
air pressure devices as this lubricant is used on
sealed fittings.
CAUTION
The multipurpose grease used during manufacture
is lithium based. Use of a non-compatible grease
could result in damage to equipment.
Specific recommendations of brand and grade of lubricants are not made here due to regional availability,
operating conditions, and the continual development of improved products. Where questions arise, refer to the
component manufacturer's manual and a reliable supplier.
