Single Leaf Bascule Bridge – Powered Drawbridge Used to Temporarily Span a Traffic Thoroughfare For Wheeled Loads to be Transferred

Developed for those customers who demand the very best in rugged, high capacity, custom-built industrial drawbridges, Autoquip Single Leaf Bascule Bridges can temporarily span a traffic-way such as a railway spur, alleyway, or dock traffic area to provide an elevated loading platform for heavy vehicles.

Single Leaf Bascule Bridges are rated for outdoor duty and available with vehicle capacities to 60,000 pounds and platform lengths to 20 feet long for one or two lanes of traffic. The hydraulic bridge leaf or platform can be raised and safely stored in the full vertical position when not in use, eliminating the possibility of interference with rail or other cross-traffic.

Autoquip has designed and manufactured Hydraulic Bascule Bridges in America's heartland for over 35 years.

We excel at providing our customers with specialized, custom-built solutions at the lowest possible price and with the shortest possible lead-time. Our technical sales and design experts walk each customer through an application review, complete a design concept, and generate quotes and proposal drawings specific to the requirements of each application. 

Features and Benefits

Durability and Quality

  • Joints, the most critical wear points in the lift, feature chrome-plated, 100,000-psi, ultimate-strength pins for premium load strength and long life.
  • Minimum ¼ inch thick steel reinforced platform minimizes deck deflection, maximizes load stability, and extends life of the platform deck.
  • Structural steel channels in the transfer bridge ensure additional rigidity and resistance to twisting or bending of the unit under load.
  • Chrome plating improves durability of the rods and extends the life of the cylinders and the seals.

Maintenance and Warranty

  • Maintenance-free bearings at pivot points require no lubrication.
  • Heavy duty remote power unit with weather-proof cover offers easy access for inspection and maintenance.

  • Non-skid surface minimizes slipping & loss of traction in wet 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.
