*For 2-10t capacities, the customer’s substructure must account for
the moment MT (torque) from the rope drum. Therefore it must be
torsion resistant and level, (max permissible offset, Y = .0787in.)
**For 15-20t capacities, the design structure accounts for the
moment, and the forces are diverted to the fixation points.
