Abstract
Lubrication devices for lubricating wire rope on a crane. Spray nozzles may be permanently mounted to the multi-sheaved wire block assemblies. A controller and oil supply located near the base of the crane are used to control and deliver oil to the spray nozzles. A telescopic spray unit is used to lubricate the vertical stationary wire rope. A crawler that rides on the wire rope is used to lubricate the stationary wire rope between the anchor point and the first sheave of the block assembly. Improved clamshell units are used to lubricate the wire rope between the drums storing wire rope and the first sheave.
