ABSTRACT:
A test stand for allowing the testing of both a pull-type lifting apparatus and a push-type lifting apparatus. The test stand includes a base and a carriage component, the carriage component including a load transmitting section and a sensor receiving section. The load transmitting section and the sensor receiving section are spaced apart by spacing members. The spacing members are slidably mounted to the base for allowing a sliding movement of the carriage component relative to the base between a retracted configuration and an extended configuration. A load sensor provides a measurement of a force biasing the carriage component towards the extended configuration. The carriage component is configured and sized for allowing the push-type lifting apparatus to be inserted between the base and the load transmitting section so as to bias the carriage component towards the extended configuration and for allowing the attachment of the pull-type lifting apparatus to the load transmitting section so as to bias the carriage component towards the extended configuration.
