Mechanical requirements for TLS with a hydraulic system and electric drive

Mechanical requirement on the crane for implementation of the TLS function:
● Defined configuration of
– Cylinders (equipped with proportional valves for continuous velocity control)
– Hoist cables
– Spreader suspension
● An electric drive at the tip of the boom hoist

The figure above shows a schematic mechanical structure at the tip of the boom hoist. Four
guide pulleys (R1-R4) guide the hoist cables. An electric drive with a spindle is also installed.
The hoist cables
linear movement of the electrically driven spindle
(skew CW) or counterclockwise (skew CCW). In this way, skew damping can be implemented
by the electric drive.
The cylinder and electric drive interact as follows:
