Abstract
A load-cancelling system for conveyance systems, such as elevators, is especially adapted for cancelling the effect of the load weight on power requirements and includes at least one weighing device adapted to determine the weight of the load in the elevator. The system also includes a brake adapted to dissipate energy from the conveyance system and interface means between the weighing device and the brake for translating the result of the weighing operation to a corresponding braking operation.
Claims10
A load-cancelling system, for conveyance systems having a power source, driving means and braking means, said load cancelling system being adapted to cancel the effect of a load weight on the requirements from the power source and comprising at least one weighing device adapted to determine the weight of the load on the conveyance, a supplementary braking device adapted to dissipate energy supplied to the system by the load and interface means between said devices for translating the result of the weighing operation to a corresponding braking operation.
A load cancelling system, for conveyance systems having a power source, driving means and braking means, said load cancelling system being adapted to cancel the effect of a load weight on the requirements from the power source, and comprising at least one weighing device adapted to determine the weight of the load on the conveyance, a supplementary braking device adapted to dissipate energy supplied to the system by the load when the load adds energy to the system and dissipate energy equivalent to the difference between full load and the existing load when the load requires energy from the driving system.
