Reduced Capacity Lift Charts
The Reduced Capacity Lift Chart system was conceived to inform the end user of the allowable
loads which can be lifted off the sides of a mechanics truck. IMT devised a color-coded chart
defining the sectors where less than hydraulic crane capacity can be lifted. The color-coded
chart (Reduced Capacity Lift Chart or RCLC) corresponds to a visual indicator on the base of the
crane. The RCLC displays the percentage of the hydraulic crane capacity to be lifted in each
sector. The visual indicator on the crane base gives the operator a reference of the sectors. With
this information the end user can more safely use the mechanics truck. Stability confirmation
yields data to produce a Reduced Capacity Lift Chart if necessary. Some units may not require
de-rating over the sides, but a majority will.
If the IMT crane is installed by an IMT distributor, the distributor is responsible for stability
confirmation. IMT supplies a generic RCLC decal for dealer installation.
CAUTION
CHASSIS WEIGHT, SUSPENSION, AND UNIT SET UP, INCLUDING NUMBER AND TYPE
OF STABILIZERS, LIFTING SURFACE, ETC., HAVE A SIGNIFICANT IMPACT ON
STABILITY.
The basic illustration shows full crane capacity off the rear of the truck and reduced capacity
when lifting over the sides. Lifting over the front of the truck is not permitted.
For an IMT 5525 crane with a standard IMT Dominator® II body, the derated percentage is 80%
in the yellow quandrants. For an IMT 6025 crane with a standard Dominator II body, the derated
percentage is 70% in the yellow quadrants.
