摘要： The present invention relates to traction and traction- loading hoists which are mounted on vehicle for improving their progression capability, for helping other vehicles which are blocked, for dragging loads onto the platforms of vehicles as well as for lifting or lowering loads The hoist of the present invention comprises the following members mounted on two supports: a winding drum, a winding drum switching mechanism that disconnects said drum for unwinding more rapidly the hoist cable, a reduction gear which is in the shape of one conical and one planetary gears connected by a linking shaft and has a lower reduction ratio than that of the current ones; and a mechanism for stopping the winding drum which is made in the shape of a toothed free-wheel clutch. In order to lower a load which has been previously lifted, the hoist comprises a brake sistem usually connected to an energyaccumulator. In order to increase the braking action, the hoist may also include a braking chamber having its control connected to the clutch control of the vehicle. The potential yield of this hoist is higher than that of similar devices.

摘要： PURPOSE:To smoothly, safely, and continuously make horizontal and vertical transport, for example carrying in materials such as segment into underground through a pit. CONSTITUTION:A pair of parallel guide rails 10 are laid in continuity to a horizontal transport part 10A. and a vertical transport part 10B, and a transport frame 20 is suspendedly supported by the two guide rails 10 through one shaft. The guide rails 10 are provided with rack, and a pinion gear meshing with the rack is mounted on the drive shaft of the frame 20, and this is driven by a motor to generate movement of the frame 20 in the horizontal transport part 10A. A driving rope 30 operated by a winch is stretched over the vertical transport part 10B, and the rope 30 is set on pulleys 26a, 26b on the drive shaft with horizontal movement of the frame 20, and elevation and sink of the frame in the vertical transport part 10B is made with operation of the rope by the winch.

摘要： PURPOSE: To simplify a configuration and an assembling operation for a tire lift device, make its cost minimum, prevent a backup of a spool and perform a fast taking-up of a cable on the spool. CONSTITUTION: A spool 60 is comprised of a first annular plate member 62 and a second plate member 74 made of a powdered metal and a track 76 for winding a cable 80 in a spiral overlapping manner is formed between the plates. An annular inner tooth gear 96 is integrally formed at the second plate 74. An outer tooth gear 118 positioned inside the inner tooth gear 96 is integrally formed with a control plate 115 made of a powdered metal. The inner tooth gear 96 has some inner protrusion teeth 98 spaced apart in a circumferential direction. The outer tooth gear 118 has some outer protrusion teeth 119 engaged with some inner protrusion teeth 98, and each of the teeth of both gears has a leading surface and a trailing surface. The leading surfaces and the trailing surfaces of the different two teeth of the outer teeth gear 118 are concurrently contacted at two points 124 with the corresponding rear edge surface and front edge surface of the teeth of the inner teeth gear 96.
