NEW ADDITIONS TO SMC PERSONNEL ELEVATORS

Sidney has added two major items to their line of “Special Purpose Personnel Elevators” to comply with the new requirements of the A17.1-2000 Safety Code for Elevators and Escalators. Shown in the above photo is the Sheave Brake as required by Rule 2.26.2.29 Ascending Car Overspeed Protection Device. Also added in the control panel and hoistway wiring is the Unintended Car Movement Device as required by Rule 2.29.2.30.

In the event of an over speed of the car in the up direction the Sheave Brake will activate and pinch the hoisting cables between two friction pads stopping the movement of the car and counterweight. In the event the car should move more than 48” either up or down, away from a landing for any reason while either the car or landing door is open the Sheave Brake will activate and pinch the hoisting cables, stopping the movement of the car and counterweight.

Single Automatic Operation Push Button Control

SMC has engineered, developed and successfully tested their Single Automatic Push Button Control for their Special Purpose Personnel Elevators. The standard control for the up or down travel is continuous-pressure operation, which means that you have to maintain constant pressure on the up or down push button and manually level the car. The Single Automatic Control has been successfully tested for months and is now available as an option. Definition of Single Automatic Operation per ASME A17.1-2007/CSA B44-07: “single automatic operation by means of one button in the car for each landing served and one button at each landing, so arranged that if any car or landing button has been actuated the actuation of any other car or landing operating button will have no effect on the operation of the car until the response to the first button has been completed.” The Sidney Single Automatic Operation Push Button Control has built in as standard the soft start and soft stop feature.
