The First 2-Speed Gearbox Designed with a Drop Leg Jack in Mind.
BULLDOG’s 2-speed 12,000 lb. support capacity square jack makes cranking easier when fully loaded and faster when unloaded. In low gear, the ratio delivers full lifting power at a supersmooth, easy-lifting 27 turns per 1" (planetary) and 29 turns per 1" (traditional) of travel. In high gear, the cranking ratio is a speedy 9 turns per 1" of travel, the fastest in its weight class.
- State of the art 2 speed gearbox with power and speed for the most effective and efficient jack at all loads
- Designed for today’s standard agricultural, construction and industrial trailer applications
- User friendly design makes operation smooth and easy
- Engineered alloys for enhanced strength, stability and sideload capability
- Planetary gearbox fits within the width profile of the jack’s outer tube,
eliminating the need for spacers
