摘要： A winch mounted to an automobile bumper and comprising a cable winding drum rotatably mounted between a main drive housing and an opposite end idler housing. The main drive housing has a main lower section of integral box-like construction and an open top closed by an upper housing section. The drive end of the drum and an intermediate drive member are inserted laterally into the lower housing through access openings, and are retained in place by a downwardly inserted retaining plate. The remaining drive components are inserted into the lower housing section through the top opening or positioned in the upper housing section. This construction provides for easy assembly of the drive components, with box-like construction of the main housing being better able to withstand the substantial force loads exerted thereon.

摘要： A winch brake device that is used for a work machine and generates a braking force on the basis of a brake manipulation, includes a pressing member that brings braking members into pressure contact with each other to generate the braking force, a first brake cylinder that applies a first pressing force for bringing the braking members into pressure contact with each other to the pressing member, and a second brake cylinder that applies a second pressing force different from the first pressing force to the pressing member. The first brake cylinder and the second brake cylinder are capable of applying the first pressing force or the second pressing force independently of each other.

摘要： In a hoist and traction machine including a free rotation control apparatus, a free-rotation spring 19, for urging an operating handle 18 toward a driving member 8 and also urging the driving member 8 in the brake releasing direction, is interposed between the driving member 8 and a stopper 17 provided on a driving shaft 5. When the operating handle 18 is pulled out, the driving member 8 is rotated to move away from a driven member 7 by a torsional urging force of the spring 19 and thereby a braking ratchet wheel 11 and braking plates 9, 10 is released. Engagement lugs 31 are then brought into resilient contact with free rotation surfaces 35 via an axial urging force of the spring 19 to maintain controlled free-rotation.
