Ton Bossman Jacks
100 and 150 Ton Bossman Jacks
Duff-Norton's 100 and 150 ton capacity Bossman jacks are designed for jacking mining and construction equipment for maintenance. Sturdy steel frame. Three large pneumatic tires and swiveling handle for easy maneuverability. Pneumatic tires flatten under load to allow base to contact floor.
Patented locking mechanism: spring-activated locking shoes engage while lifting and lock into place every 1/2" to eliminate the need for blocking. When lowering, air pressure allows the locking shoes to disengage until the operator releases the lowering button.
Remote operation capability allows the operator to use the jack from a distance
Air/hydraulic pump operates with 50 CFM at 90 PSI air pressure to lift full load
Overall length is 52" - large base provides stability under load
