Abstract
An improved measuring device for measuring the load of an elevator including a car suspended by a tension member within a termination (36) at one end of the tension member (28), a mounting plate (42) for attaching the termination relative the hoistway, and a hitch (38) for attaching the termination to the mounting plate further including load cell (56) positioned between the hitch and the mounting plate wherein the load cell generates a signal proportional to the load of the car
Claims16
A measuring apparatus for measuring the load of an elevator including a car suspended by a tension member within a hoistway, a termination at one end of the tension member, a mounting plate for attaching the termination relative the hoistway, and a hitch for attaching the termination to the mounting plate, the apparatus comprising:
- a load cell positioned between the hitch and the mounting plate wherein the load cell generates a signal proportional to the load and wherein the load cell defines a hole for allowing the termination to pass therethrough.
A measuring apparatus for measuring the load of an elevator including a car suspended by plurality of tension members within a hoistway, and a termination at one end of each of the plurality of tension members, the apparatus comprising:
- a mounting plate for attaching the plurality of terminations relative the hoistway,
- a plurality of hitches for attaching each of the plurality of terminations to the mounting plate;
- and
- multiple load cell positioned between each of the plurality of hitches and the mounting plate wherein each load cell generates a signal proportional to the load.
