Web• A moving scissor lift is near a fixed object. • A moving vehicle and the scissor lift are operating closely. • The scissor lift passes under a fixed object, such as a door frame or a support beam. Positioning the scissor lift to . avoid electrocution, arc flash, and thermal burns is important for safely using scissor lifts WebFor each 360° revolution of the screw, the form has advanced axially by the pitch of one thread. This has the same value as the pitch. In the case of a single start thread, lead and pitch are equal. Double Start Thread: Two thread forms. During 360° revolution the forms advance axially by the combined pitch of two threads. Lead is 2x the pitch.
