A 25-ton truck-mounted hydraulic crane is being used on a construction
site. The maximum horizontal distance from the center of rotation of the
crane to the hoist line of the crane when lifting a load of 9,000 lbs will
be 40 ft. Use Table 16.2 crane data to select the minimum-length boom
required to safely hoist the load.
Solved the problem and show complete solution.
