invention and are not to be interpreted as limiting the scope of the instant invention while the invention has been described with a certain degree of particularly it is to be noted that many modifications may be made in the details of the invention 39 s construction and the arrangement of its components without departing from the spirit and scope of this disclosure it is understood that the invention is not limited to the embodiments set forth herein for purposes of exemplification in the present invention a high torque low rpm hydraulic motor is utilized to control the descent of an elevator car down an elevator shaft in one embodiment the hydraulic motor is attached to an elevator car the motor has a cog attached to it that rides along a stationary track that extends the length of the shaft when the elevator descends pressure builds up within the hydraulic motor and the speed with which the cog may turn and move down the track is limited when the cog turns in the other direction as it ascends the shaft no pressure builds within the hydraulic motor due to a check valve and the cog rotates freely thus not limiting the speed with which the elevator may ascend the shaft those skilled in the art will appreciate that all hydraulic motors rotate easily in one direction due to a check valve but only slowly in the opposite direction due.
