Talbert Manufacturing designed its new 75-Ton Double Schnabel Trailer to provide safety and stability in wind energy and heavy-haul construction transport.
Talbert Double Schnabel Trailers are self-sustaining and self-loading with hydraulic-lift capabilities that eliminate the need for cranes during load or unload. The trailer can be converted for use in heavy-haul construction transport with optional components.
Units are also available in single and multiple combinations for wind towers. Talbert Double Schnabel Trailers are self-sustaining and self-loading with hydraulic-lift capabilities that eliminate the need for cranes during load or unload.
Talbert Double Schnabel Trailers feature a 13-axle hauling configuration designed for two hauling applications - either an 80-meter wind tower base, or a wind tower mid-section. The main upper-front and rear goosenecks are standard HRG style, and pinned in place on a column-style hydraulic Schnabel tower. The lower rear of the tower is equipped with two removable banana-style flange adapter plates for two tower sections. Units are equipped with both mechanical and remote rear steer capability.
"Versus conventional alternatives, our Double Schnabel Trailers provide enhanced safety and stability during transport due to a wider (8-foot) interface area for the load at the top," said Clarence Schubach, Talbert engineer. "Traditional units offer a significantly smaller interface area which may lead to potential damage to the tower."
According to Schubach, the interface area on the Talbert trailer is covered with an ultra-high molecular weight plastic material to prevent abrasion resistance against the tower.
The upper Talbert "power tower" is equipped with removable and adjustable upper guide tubes, which minimize any rolling of the tower section during transport; and all Talbert Schnabel and power tower main hydraulic and air operated controls are on the side of the gooseneck. The operator does not have to climb on the unit to engage lock pins.
The front Talbert Schnabel gooseneck is attached to a 3-axle jeep dolly with a 60-inch sliding fifth wheel to assist with the proper load distribution. The rear Talbert Schnabel gooseneck is attached to a 6-axle rear steer dolly that is rated for a 120,000-pound load. This steer dolly is extremely versatile and can be used in alternate trailer configurations depending on load requirements.
All 6 axles on the Talbert steer dolly are 10 feet wide for increased roll stability and safety. The front 3 axles are fixed and non-steerable. The rear 3 axles are designed for progressive steering, as the sixth axle will steer the maximum of 30 degrees. The unit can also be adjusted to steer faster or slower depending on the length of tower section being transported.
