Flexibility & Ease of Use

  • Single and Double Leaf Bascule Bridges – One-touch operator controls automatically engage and disengage safety wings during raising and lowering sequences.
  • Mini Bascule Bridge — Simple and reliable wall-mounted operator controls offer the operator complete visual contact of the lift during raising and lowering.

Durability & Quality

  • Chrome plated, 100,000 psi, ultimate-strength pins provide premium load strength and long life at hinge points.
  • Minimum 1/4-inch-thick steel-reinforced platform minimizes deck deflection, maximizes load stability, and greatly extends the life of the platform deck.
  • Structural steel channels in the transfer bridge provide rigidity and stability under heavy axle loads, ensuring many years of trouble-free use.
  • Chrome-plating improves rod durability and extends the life of cylinders and seals.


  • Single and Double Leaf Bascule Bridges – Hydraulically-operated bridge safety wings provide a stable and permanent structure for the bascule bridge to rest against during storage, relaxing the pressure in the hydraulic circuit.
  • Non-skid surface minimizes unexpected slipping and loss of traction in wet operating conditions.
  • Hydraulic velocity fuses completely stop lifts in the unlikely event of uncontrolled descent due to sudden hose rupture.
  • Minimum 3:1 structural factor of safety makes these bridges the most structurally sound bridge in the industry.
  • Compliance with recognized national standard
  • NFPA 70 – National Electric Code
  • ASTM – A36 – Structural Steel Standard
  • ANSI Z535 – Safety Labeling Requirements
  • AWS D.1 – Welding Standards
  • Applicable portions of OSHA 29CFR1910 – General Workplace Safety

Maintenance and Warranty

  • Maintenance-free bearings at pivot points require no lubrication.
  • For Single and Double Leaf Bascule Bridges, a heavy-duty remote power unit with weather-proof cover is easily accessible for inspection and maintenance.
  • Double wire braided Parker hydraulic hoses resist wear, abrasion, and leaks.
  • Industry-best 2-year warranty on all parts provides assurance you’ve purchased the most reliable drawbridge in the industry and demonstrates that Autoquip stands behind every dock product and loading platform sold.
