Holland Moving & Rigging Supplies has introduced a 150-ton hydrostatically driven module initially designed for transporting 300-ton bridge tub girders. Each module consists of two 75-ton Holland Dollies each containing two hydraulic lifting cylinders. Sitting on top of the four hydraulic cylinders is a bolster and turntable. The turntable allows the dollies to pivot under cumbersome loads while traveling from the factory to the barge loading dock.

In use, two 150-ton modules are placed under the load and electronically steered via wireless remote control. King pin steering allows the wheels to turn at the axles similar to a car. Articulated and crab steering allows the units to maneuver in tight quarters.

The two 150-ton modules can be used as an alternative to a standard platform trailer. Load tracking makes the two independent modules work together as if they were physically connected as one unit, the company said. The rear module uses sensors to track the location of the turntable and adjusts the wheels on the rear module automatically. This option allows the operator to focus on the front module alone versus trying to control both simultaneously.

Holland Moving & Rigging Supplies is located in Forest City, IA is an OEM that has been providing products for the heavy transport industry for more than 30 years. HMR Supplies also uses its diverse manufacturing capabilities, 3-D modeling software and experienced personnel to design, test, certify and deliver custom designs for unique heavy material handling needs.
