The DSM / Mayhew SD-54 "Sabertooth"

Maximum Capacities

This drill is recommended for operation with a maximum drill string static load (including yoke, swivel, kelly drill
pipe, collars, etc.) of 55,000 lb. (24,9482kg) on 6 lines.

When operating with static load near maximum, avoid inducing dynamic load that may cause the total load to
exceed maximum. Operation exceeding this limit may result in equipment overload and possible collapse or falling components that may be hazardous to personnel.
