SmarTork™ revolutionary design overcomes wind velocities on elevator hoistway doors by an increase of up to 20% tension at last 2 inches of closing and decreasing tension in opening cycle reducing force and amps to the elevator door operator.
Over 1,000,000 cycles (Testing By Columbia Elevator) show no significant deviation from torque and tension ratios. Access our test results.
SmarTorks'™ "Unihub" makes it interchangeable with most square shaft or dual pin mounting brackets.
Please take a moment to view our video demonstration and read our testimonials. SmarTork™ meets or exceeds ASME A17.1 and related codes. Read more about SmarTork™....
