Derrick Capacity & Reaction Calculator (DCRC) Introduction The DCRC will allow the user to input known physical loads (lifted load) and Derrick dimensions (boom length, boom radius, mast height, sill length) for TIMBERLAND Portable Derricks. DCRC will then quickly calculate all member forces and reactions. DCRC will tell the user if the load chosen to be lifted at the given boom radius and swing angle is acceptable, or if it overloads the Derrick. The user can also determine the maximum allowable load that can be lifted at a specified boom radius and swing angle. The structural properties of each of the members of your specific Derrick (boom, mast, legs, sills), as purchased originally from TIMBERLAND, must be entered in strict accordance with the dimensions provided in your derrick user manual.
