What is the main function of the electric motor on the Type-H cable support system?

• A. Drive the hydraulic unit to either push or pull the mechanical transmission assembly
• B. Rotate the tensioning spool
• C. Power the limit switches
• D. Drive the pump that lubricates the system

Answer: (A)

The motor’s job is to power the hydraulic unit that drives the mechanical transmission assembly, producing the push or pull needed to adjust the cable tension or position. The hydraulic actuation provides controlled linear motion to move the transmission, which is how the Type-H system changes tension on the cable supports. Rotating a tension spool isn’t how tension is applied in this setup, limit switches are sensors that indicate end positions rather than provide the motion, and the lubrication pump, if present, is a separate function not driven by the motor for the primary movement of the system.
