Liebherr Crane LR 1750 SL Load Chart Manual 074734 – PDF DOWNLOAD

Explanations:

1.1 The load capacity values in the load capacity tables are indicated in tons [t].
1.2 The working radius is the horizontal distance indicated in meters [m] between the centre of gravity of the load centre of gravity from the slewing axis of the crane’s superstructure as measured from the ground. This also applies when the crane is subjected to loads; i.e., this includes boom flexure.
1.3 Boom positions other than those specified in the load capacity tables are prohibited.
1.4 The boom must only be moved in those ranges for which load capacity values are given, even without a load, as otherwise the crane can topple. In normal operations, this is prevented by the overload safety device. When “Assembly” is engaged (with the assembly key-operated switch) the boom must only be luffed or lowered within the specified working radius ranges.
1.5 The given load capacities include the weight of the slinging tackle, hoisting and take-up tackle. The possible weight of the load to be hoisted is thus less than the weights above.
