Abstract
A fluid-operated hoist and method for operating a fluid-operated hoist. The hoist is particularly convenient to produce and install and can be permanently and reliably operated without frequent maintenance. The hoist includes a fluid supply line supplying an operating fluid to the hoist for operating the hoist, a generator connected to the fluid supply line for generating electricity by the operating fluid, and an electrical consumer on the hoist that is operated by the electricity generated by the generator.
Claims16
A compressed air-operated hoist, comprising
- a fluid supply line supplying compressed air to the hoist for operating the hoist,
- a compressed air generator connected to the fluid supply line for generating electricity by means of the compressed air, and
- at least one electrical consumer on the hoist, which is operated by the electricity generated by the compressed air generator.
A method for operating a compressed air-operated hoist, comprising the steps of:
- supplying compressed air as an operating fluid to the hoist via a fluid supply line,
- supplying the operating fluid to a compressed air generator of the hoist and generating electricity by means of the compressed air, and
- conducting the generated electricity to at least one electrical consumer of the hoist.
A method for operating a compressed air-operated hoist, comprising the steps of:
- supplying compressed air as an operating fluid to the hoist via a fluid supply line;
- supplying the operating fluid to a compressed air generator of the hoist and generating electricity by means of the compressed air;
- conducting the generated electricity to at least one electrical consumer of the hoist;
- and
- interpolating a starting time based on the current rotational speed of a starting motor of the hoist when the motor has started.
