Avoid traveling with a suspended load. Before swinging (or if required, traveling), bring the load into an arm position (radius and height) that has a safer weight capacity rating and adequate movement clearance. The operator and all work site personnel should be thoroughly familiar with safety instructions and procedures within this Operation and Maintenance Manual. The following weight loads are in compliance with SAE (J1097) and ISO applicable, recommended standards for hydraulic excavators performing lifting operation on a firm supporting surface. An asterisk (*) next to the lift rating indicates rated load does not exceed 87% of hydraulic capacity.
All other ratings have been determined not to exceed 75% of tipping capacity. Do not attempt to lift or hold any load that exceeds rated load capacity at the specified distances (from the machine's rotation center line and height - see "lift radius" and "lift height" in the reference drawing, Figure 47). Lifting Radius Centerline of Rotation Lifting Point Lifting Point Height Ground Line (Machine Supporting Surface) FG027264 Figure 47 The weight of slings and any auxiliary lifting device (and/or the weight difference of any attachment heavier than standard configuration) must be deducted from the rated lift capacity to determine allowable net lifting load.
The lift point should be on the back of the bucket, as shown in Figure 47. IMPORTANT Select the Digging Mode switch on the Instrument Panel before using the excavator for lifting work. Engine and hydraulic oil should both be fully warmed up to operating temperature before starting a lift. OP001759 1-47 Safety
