Well-planned detail desig n makes erecting work easier.
The complete jib is pre-installed on the ground. The trolley and the load hook form a single assembly unit. Reeving and tensioning the trolley rope is fast and easy without connection to the mains, since the drum can be rotated freely with the brake released. Fast hoist rope reeving. The hoist rope on Liebherr top-slewing cranes is installed by simply pulling it over the tower head and running it through the trolley to the hook. On Liebherr’s top-slewing cranes, the hoist rope pulley at the trolley hook block is simply folded open for easy hoist rope reeving. Once the hoist rope has been guided through the pulleys, the erecting mechanic moves out to the end of the jib in the trolley‘s cage, bolts the hoist rope into position – and the job’s done! Quick-release fastenings for trouble-free assembly. The quick-release jib and counter-jib fastenings make erecting work significantly easier. The jib and counter-jib can even be installed without difficulty in an inclined position.
