EXCAVATOR RATED LIFT CAPACITY TABLES WARNING! All rated lift capacities are based on the machine and the load both remaining level at all times. DO NOT EXCEED THE RATED LIFT CAPACITY. Lifting loads greater than those shown in the rated capacity tables can cause catastrophic equipment failure and/or structural collapse of the machine. To operate safely the excavator should be on a firm, level and uniformly supporting surface. The operator is expected to make due allowance for all specific work site and lift-related conditions, and respond to changes in those conditions that could pose a hazard. The following could all cause hazardous conditions and accidents or injuries:
Soft or uneven ground. Off-level terrain. Side loads. Modifications or poor maintenance of the excavator. Failure to lift squarely over the end or over the side of the machine. When a load is in the air, the operator must remain alert. Avoid side loads that may be caused by uneven slings, traveling with the load or swinging too quickly. The load can become unbalanced if the hookline is twisted and starts to rotate. If the surface area of the load is large enough, wind gusts can create side loads. Keep the bucket hook point directly over the load. Taglines on opposite sides of the load can help maintain greater stability against side loads and wind gusts.
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 centerline and height - see "lift radius" and "lift height" in the reference drawing, Figure 43). 022-00058E Operation and Maintenance Manual Safety 1-41
