Liebherr 200DR 5/10

Maximum load moment is 200 tonne-metres and maximum radius is 25 m. As standard, it can hoist components for tower cranes, in the 300 tonne-metre class and larger, down from a height of 320 m. The dimensions and weights of all the parts of the new crane are designed to enable them to be dismantled with the aid of a small hoist and removed via lift shafts in buildings.

Depending on the application, the new crane can be configured with load moments of 100 or 200 tonne- metres. For optimum force distribution, supports for the 200 DR 5-10 are articulated and can be adapted to suit the substructure of the building. Using a jib for a maximum radius of 20 m, loads of 10 tonnes can be hoisted in double-reeved operation out to full radius. The jib used for a 25 m radius can hoist 7.5 tonnes at the tip.

Frequency-controlled step-less drives are used on all motions and are 37 kW for the luffing gear and 45 kW for the hoist gear. All movements are monitored by the SPS control system used in all Liebherr luffing jib cranes. Sensors monitor and safeguard the hoisting height, load moment, jib inclination and slewing gear. Operation is by radio remote control.

Simple hoisting equipment is used to dismantle the derrick crane so no additional crane is required. Liebherr supplies a package consisting of a high-lift truck, fork-lift truck with weighing equipment and a collapsible workshop crane. Maximum dimensions of individual parts are 2.20 x 1.10 x 1.10 m and maximum component weight is 1,000 kg.

Some Notable Projects 200DR 5/10 Participated

• Dismantling tower crane on the 264m high Al Kazim Tower in Dubai.
• Dismantle the 354m high Federation Tower in Moscow, Russia – One of the tallest building in Europe.
• Morrow Equipment purchased the Liebherr 200 DR 5/10, introducing it to the North American market in 2009. The derrick crane was leased to Seattle-based Sellen Construction to dismantle a Liebherr 355 HC-L luffing tower crane.
• Larsen & Toubro (L&T) ordered the first 200DR 5/10 in India in 2013. It was used to dismantle a tower crane on one of the country’s tallest commercial building, the 50-storey 203metre Kohinoor Tower in Mumbai.
• The Liebherr 200 DR 5/10 was used to dismantle a Liebherr 355 HC-L 12/24 Litronic luffing tower crane from the roof of the new Courtyard Marriot Hotel in Montreal, Canada in 2018. The 355 HC-L climbed to a maximum hook height of over 130 metres during the construction of the 42-storey hotel.
