Jun 11, 2019· The elevator car is balanced by a heavy counterweight that weighs roughly the same amount as the car when it's loaded half-full (in other words, the weight of the car itself plus 40–50 percent of the total weight it can carry). When the elevator goes up, the counterweight goes down—and v-versa, which helps us in four ways:
A braking dev is described for an elevator having a governor that actuates above a tripping speed for braking an elevator car or counterweight that is guided on a vertical guide rail. The braking dev includes a unitary safety housing attached to the elevator car or counterweight and at least partially surrounding the guide rail. The safety housing is expandable and has opposite, facingCited by: 24
Mar 25, 2010· The clearance between counter weight and the counterweight screen and between the counterweight and the hoistway enclosure shall be not less than 19 mm. Car or machine counterweights not located in the elevator shaft shall be entirely enclosed on all sides. Cage and Platform: a. specification materials and dimensions;
Elevator: In traction (non-hydraulic) elevators, a heavy counterweight counterbalances the load of the elevator carriage, so the motor lifts much less of the carriage's weight (specifically, the counterweight is the weight of the carriage plus 40-50% of its rated capacity). The counterweight also increases the ascending acceleration force and decreases the descending acceleration force to
Jul 09, 2017· From the Otis website there's this explanation: "To reduce the load on the motor, the counterweight is calculated to match the weight of the car and a half-load of passengers. As the car rises, the counterweight descends, balancing the load. This
Elevator Specifications. A feature-loaded hydraulic elevator, such as Elvoron from Garaventa Lift, should have a number of features. The power rating for a single phase drive motor is 240 VAC, 30A, and 60Hz, and for a three phase drive motor it is 208 VAC, 20A, and 50Hz or 60Hz.

The braking dev includes a unitary safety housing attached to the elevator car or counterweight and at least partially surrounding the guide rail. The safety housing is expandable and has opposite, facing
An elevator installed in an elevator shaft has a cage, a counterweight, hoist cables suspending the cage and the counterweight, and a driving unit disposed outside a space in which the cage moves vertically in the elevator shaft, and provided with drive sheaves around which the hoist cables are wound to move the cage and the counterweight in the elevator shaft by the driving unit.
