Abstract: For providing a chain lever hoist that can ensure a stable free rotation operation over a long term with a simple design, improvement is made in the chain lever hoist wherein an engaging pawl is switched to a neutral position, at which the engaging pawl is not allowed to engage with engaging teeth in the forward direction or a reverse direction, by the operation of a selector lever and then a load chain on the non-loaded side is pulled or an operating handle is rotated in the reverse direction to thereby produce the free rotation state just the way it is, the improvement being such that the operating lever is rotatably supported on a brake cover at its opening with a predetermined spaced interval from a first hub. By virtue of this, the first hub is allowed to rotate together with the drive shaft, without contacting with the operating lever, during the free rotation operation, and as such can attain reliable free rotation operation.

Abstract: The most commonly used spring type chain lever hoists suffer from a major drawback in that, if the chain is drawn quickly over the load sheave while it is set for free running operation, the brake will automatically be applied and the free running movement terminated. Similarly, if a light load is suspended from the chain, the weight of the load may be insufficient to activate the brake with the result that the load will be wound down dangerously quickly, leading on occasion to accidents. The present invention is designed to resolve these potentially fatal flaws by enabling a hub, which screws freely onto a spindle in the conventional manner, to be rotated through a few degrees into a prescribed lock position relative to the spindle and then locked there either temporarily or permanently as required.

Abstract: The free-running operation of a load sheave of a chain lever hoist is assured by an assist mechanism that keeps the relative position between a hub and a spindle of the hoist at a brake inactive position, when the screwing control position of the hub relative to the spindle has been shifted from a winding operation position to a free-running operation position. operator can easily switch the hoist to the free-running operation made by slightly turning a hub knob and a spindle knob by hand. Such an operation eliminates steps such as holding the chain by hand, or turning the spindle while the hoist lever is engaged with the hub. The above operation frees an operator from getting his hands dirty with the chain, and permits an immediate switching to the free-running operation. The use of indicators allows the operator to recognize the free-running operation setting at a glance.

Abstract: The most commonly used spring type chain lever hoists suffer from a major drawback in that, if the chain is drawn quickly over the load sheave while it is set for free running operation, the brake will automatically be applied and the free running movement terminated. Similarly, if a light load is suspended from the chain, the weight of the load may be insufficient to activate the brake with the result that the load will be wound down dangerously quickly, leading on occasion to accidents. The present invention is designed to resolve these potentially fatal flaws by enabling a hub, which screws freely onto a spindle in the conventional manner, to be rotated through a few degrees into a prescribed lock position relative to the spindle and then locked there either temporarily or permanently as required.

Abstract: If the load applied on the load sheave is small, the pressing drive member contacts tightly with the friction members to make secure the braking of rotation of the drive shaft, so that the small load is prevented from moving downward by its own gravity, and moreover the operation wheel is engaged with and held in the rotation limiting member spline-coupled with the drive shaft so as to be free to idle even in a no-load state, and a spring for pressing the operation wheel to the rotation limiting member is inserted between the outer end surface of the operation wheel and the spring retainer held on the drive shaft projecting from the rotation limiting member.
