WET TYPE MULTIPLE DISK BRAKE COOLING DEVICE

摘要

PROBLEM TO BE SOLVED: To achieve fuel saving for a winch having a wet type multiple disk brake.SOLUTION: A wet type multiple disk brake cooling device includes at least two winches equipped with the wet type multiple disk brake, one hydraulic pump for cooling for supplying cooling oil to the wet type multiple disk brake, a distribution device for distributing the cooling oil from the hydraulic pump for cooling to the two winches at a distribution ratio calculated beforehand, and a distribution control device for calculating a distribution ratio on the basis of the magnitude of a brake load of the wet type multiple disk brake, and controlling a distribution flow rate of the cooling oil by the distribution device on the basis of the distribution ratio.
