The industry's strongest drop leg jack. The Bulldog Twin Cam features a convenient, enclosed pin mechanism with "twin cam" action that will quickly make this heavy duty.

The Bulldog Twin Cam drop leg mechanism allows an increase in vertical static capacity by using 3/4" pins to transfer forces between the drop leg and inner tune of the jack.

The unique Twin Cam drop leg mechanism actuates the drop leg pins in both directions, giving the operator full control over engagement and disengagement of the drop leg pins. The design does not rely on spring pressure alone to keep the pins in the locked position. Also, the Twin Cam drop leg mechanism maintains tighter alignment between the drop leg tube and inner tube by having engagement on both sides of drop leg tube.

This two-speed model allows for convenient cranking ratios that allow for fast operation under a wide range of loading conditions. The drop leg provides quick adjustment. Cranking at low speed the ratio is 29-1/2 turns per inch allows lifting loads up to 25,000 lbs and a high speed cranking ratio of 9 turns per inch is convenient for loads up to 12,500 lbs.

  • Compatible with Bulldog powered drive electric motor system but it reduces the lift capacity to 7,500 lbs
  • See secondary picture posted above for multiple companion jack configurations

Bulldog

1919 - In a small third floor room over his car dealership in Wausau, Wisconsin, Thomas J. Jacob begins making high-quality precision tools of his own design. His venture becomes known as the Hammer Blow Tool Company. The death of a favorite hunting dog due to an accident involving a poorly-designed trailer hitch leads Jacob to develop the first drop-forged ball-and-socket trailer hitch, which he names the "Never Lets Go" Bull Dog. More inventions follow, positioning Hammer Blow at the forefront of the trailer industry at its infancy.

1930's - Demonstration models of camper trailers built by Jacob at the Chicago World's Fair set off a period of rapid growth in the industry.

1940's - Jacob dies in 1945. His wife, Lula, takes over Hammer Blow and guides it with great success for more than 20 years.

1960's - In 1967, Lula Jacob sells Hammer Blow to Neway Equipment Company of Muskegon, Michigan, which later sells to Lear Siegler, Inc.

1970's - In 1977, private investors led by Thomas J. Reinhart purchase and rename The HammerBlow Corporation. Expansion of the mechanical jack line and related products continues for more than a decade.
