Max. Load and Boom Angle Charts
Using the Load Chart
The crane load charts list rated load for various boom lengths and load radii. There are many different
load charts depending on the various crane boom modes, counterweight options, outrigger positions,
etc. The maximum load a crane can lift is found on the load chart at the intersection of the boom length
and load radius. If the operating radius is between radii listed on the load chart, use the larger radius. If
the operating boom length is between lengths listed on the load chart, use the longer boom length.
Example:
Operating radius 72 ft
Operating boom length 105 ft
Looking at the example load chart below, the 72 ft operating radius is between the 70 and 75 ft radii. We
will therefore use the use the 75 ft chart radius. The 105 ft boom length is between the 100 and 110 ft
chart boom lengths. We will therefore use the 110 ft boom length. At the intersection of the 75 ft radius
row and the 110 ft boom length column is the crane rated load. In this case the crane is rated to lift
10,950 lbs in the current configuration.
The load chart shows the maximum allowable lifted load. Maximum load is the weight of material being
handled plus load handling equipment such as slings, buckets, downhaul weights, etc. The weight of
load handling equipment must be deducted from the maximum load rating to determine how much
payload you can lift.
