Not quite that simple, Jim (wearing my nit-picking
hat). Horsepower is work per unit time. Expending a fixed HP over a time
T results in the production of HP*T work (in oddball units). Torque is a
force times a distance. Operating under a fixed torque, T, turning the
shaft through an angle, A, results in a work performed of T*A. So, they
are interrelated, but not proportional, peaking at different RPM, usually.
The catch, as you pointed out, is keeping the HP up to par for
the job at hand; without torque, it's hard to do the job at all in a
reasonable time; without sustainable HP, you cannot keep the torque
up. Your experience with your two trucks is valuable information for all
towers to have - experience cannot be substituted.
