Definitions
- the geometry is expediently chosen so that the lower of the two angles between the cables and the guy stand is smaller than the upper one. This choice of angles results in a force component acting on the free end of the guy stand, which stresses the piston-cylinder unit holding it in tension.
- these angular relationships cannot always be achieved if the telescopic boom is only extended to a shorter length.
- the geometry is chosen so that no major changes in the tension in the guy rope occur even when the boom is rocking, because the fixed point of the guy rope is arranged so far behind the pivot point that a shortening of the rope essentially compensates. Changes in the length of the guy rope are therefore due to the reeving of the guy rope according to the invention by the choice of the fixed rope point compensated so that an undesirable winding effect of the drum of the guy winch is compensated for when rocking.
- the bearing of the deflection tensioning roller can be acted upon by a spring against its pulling direction.
- the guy stand 11 When or after the telescopic boom is erected, the guy stand 11 is set into its operating position by the hydraulic cylinder 16. Here, the brake of the winch 6 is open and the drive motor is switched to circulation. A small internal pressure of the drive motor is expediently maintained, however, so that the guy rope does not become slack during installation and erection.
