Talbert Manufacturing 6-Axle steer dolly adds capacity, control for superloads
The 6-axle steer dolly from Talbert Manufacturing offers versatility, additional steering control and extra capacity to handle self-supporting superloads for a variety of industries. The 60-ton dolly is ideal for everything from heavy, low-riding materials, such as bridge beams and steel girders, to tower sections for wind energy development.
Originally developed for use with Talbert’s double schnabel to haul wind energy components such as tower bases, sections and blades, the 6-axle steer dolly can now be used as a stand-alone product for alternate trailer configurations.
The unit comprises two groups of three axles with the axles in each group spaced at 60 inches. With a bunk between the two groups that is connected to the rear-axle bearings through a tie rod system, the total spread is 16 feet, 1 inch. This configuration allows operators to carry more weight and complies with federal bridge laws.
With such a high center of gravity, these loads have increased potential for dangerous overturn situations. The 6-axle steer dolly is 10 feet wide for increased roll stability and safety. Further, each individual axle is mounted to a radial bearing that provides a tighter steering system for a more stable platform.
The front three axles are fixed and non-steerable and feature cut-off valves and lift chains. A mechanical self-steering system allows the rear axles to turn progressively up to 30 degrees on the sixth axle. This incremental steering allows the rear dolly to more easily maneuver around a common center point. The speed of steering is also adjustable to accommodate various load lengths and the desired turning radius. An oversteer alarm is mounted on the steer dolly along with a wireless audio alarm with lights for the tractor cab.
A hydraulic power pack allows operators to override mechanical steering with a manual, wireless remote. This option is ideal for pilot car drivers escorting superloads. In addition, truck operators can adjust the bunk height from 40 inches to 50 inches to clear overhead obstacles such as electrical lines and traffic signs and obstructions beneath the unit such as speed bumps. The unit also features Ridewell Model 240 air ride suspension.
The dolly can be picked up using its four D-rings and stacked on a trailer or the front jeep for easy transport after load delivery.
