Abstract

A manually operable force exerting device 10 comprises an urging member in the form of a runner 12 that smoothly engages with a carrier in the form of a runner guide 16, and a manually manipulable urging member displacing mechanism 18 in the form of a ratchet facility 18.1 fitted in a fixed relationship to the runner guide 16. The facility 18.1 cooperates with the runner 12 in causing its displacement via linking means in the form of a belt 20 extending sling-fashion from the facility 18.1 along the runner 12 to an anchor 22. The facility 18.1 is also fitted with a release mechanism that permits the controlled unwinding of the belt 20, as rollable onto a drum, in controllably lowering a vehicle jacked by means of the device 10. The belt 20 passes along a guide roller 32 forming part of the runner 12.
