Earth-moving machinery. Hydraulic excavator and backhoe loader lowering control device. Requirements and tests1 Scope This International Standard applies to lowering control devices on hydraulic excavators and the backhoe part of backhoe loaders, when used for object handling. This International Standard establishes uniform requirements and test procedures for control devices fitted on boom, intermediate boom, dipper or arm cylinders to control the rate of drop in the case of a hydraulic line failure or rupture. This International Standard applies to machines
