Abstract
PURPOSE: To enhance the excavating depth with a larger lift by arranging two sheaving mechanisms for lifting a backet and a sheaving mechanism for operating the backet on an arm.
CONSTITUTION: As a hydraulic cylinder 20 for operating a backet is driven to unwind an operating rope 99 on the second sheaving mechanism 40 for operating the backet, the backet 30 opens. Then, a boom 11 and an arm 14 are interlocked to lower the backet 30. When a hydraulic cylinder 22 for lifting the backet is driven to unwind holding ropes 98a and 18b and the operating rope on the first and third sheaving mechanisms 70 for lifting the backet, the backet 30 lowers. Then, when the cylinder 20 for operating the backet is driven to wind the operating rope 99 with the second sheaving mechanism 40 for operating the backet, the backet closes gradually. Then, a hydraulic cylinder 22 for lifting the backet is driven to lift up the backet 30.
