This dolly has a maximum lifting height of 50″ to allow ample clearance for the aircraft’s tail to enter a low entrance hanger facility door. The maximum lifting capacity is 13,000 pounds, allowing enough power to raise the aircraft’s forward section to the allowable height. The unit’s power source is an electrically operated motor (1-1/2 HP, 1,750 RPM with brake) which operates two jack screws. Mechanics of lift is scissor type design which lends itself to proper clearances, straight vertical travel, high power-to-lift distance proportions, and lightweight mobility of the entire unit. Hook-up to aircraft takes less than five minutes due to the unique design of the removable support bar. This one-man operation is specifically designed for quick and simple usage.
