Abstract
An idling device is able to bring into an idling condition a lever hoist including a change gear provided on driving member threadedly engaged on a driving shaft for driving a sheave winding-up thereabout a chain or rope for a load, an operating lever rockably driven by a hand, winding-up and winding-off driving pawls engageable with teeth of the change gear and changeable in response to the purpose of hoisting or lowering the load, and a braking assembly for preventing the change gear from being driven by a gravity of the load and adapted to be clamped and released by rotative movement of the driving member relative to said driving shaft. According to the invention the idling device comprises brake clamped position holding means between the driving shaft and a manually operatable knob fitted rotatably and axially slidably on the driving shaft and brake over-released preventing means between the driving shaft, the driving member and the knob, thereby enabling the braking assembly to be changed from its clamped condition into its released condition and vice versa by simple operation and capable of preventing the braking assembly from excessively releasing.
