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.

A deep water lowering apparatus that utilizes dual davit structures mounted on a barge. Each davit structure has a pulling wire rope line spooled on a storage winch. Each pulling line is reeved onto a traction winch and through upper and lower sheaves on the davit structure. Corresponding ends of each pulling line are connected together on an equalizer beam. An adaptor box is suspended from a spreader bar provided with a dog leg center portion for effecting the load transfer from the crane. The lowering tool that supports the load is directly received in the adaptor box and transfers the load to the lowering apparatus without the need for rigging work.
