The Mitchell 180° Swing Loader with 20,000 lbs. lift capacity is available for the Caterpillar 930M - 966M wheel loaders.  

The Mitchell Rail Gear conversion system converts a standard Cat 930M – Cat 966M Wheel Loaders into multi-purpose Swing Loader with optional Railcar Mover system attachments. Railroaders can use the machine as a mobile railcar mover, material handler and front end loader to obtain efficient utilization of their equipment and see a high return on their equipment investment. 

The retractable Friction Drive Rail Gear is attached to the frame of the machine in such a way that allows a front-end loader to be used as a standard Wheel Loader, material handler and also as an on-rail mobile railcar mover to provide optimum performance and machine utilization. The front loader linkage that swings 180° comes with a quick coupler to accept a large variety of tools such as forks, buckets, material handing arms as well as many other tools to be able to perform various tasks on and off rail.

The rail wheels have a friction drive hub attached to them that engages with the tires. As the tire rotates the drive hub, the rail wheels are driven. The mechanical friction drive system is reliable, because is it uses the road axle drive line system for propelling and braking. When the loader is on rail, the articulated frame is hydraulically locked to keep the front and rear rail wheels in alignment. Depending on the environment, the machine can be equipped with air filled, foam filled or solid rubber cushioned tires.

The optional Mobile Railcar Mover package consists of adding a rear weight transfer coupler and train air brake system. The weight transfer coupler has a shelf-type railcar knuckle. When the weight transfer coupler is engage with the coupler on the railcar, a pre-determined amount of weight can be transferred from the railcar to the Hi-Rail Gear wheels that increase the Hi-Rail Gear wheel traction. The 24 CFM train air brake system controls the braking system of the railcar from the cab of the Swing Loader.

When considering the high cost associated of maintaining a specialty built mobile railcar mover in addition to the required normal maintenance of a customer’s existing front-end loader, the decision to combine multi-functions into one machine makes good economic sense. The Cat 930M – 966M wheel Loaders makes a good choice for a base unit because of the durability of the engine and drive line system. The highest cost of railcar mover machine failures is the engine and drive line system. The Cat 930M -966M front-end loaders are manufactured with far more durable drive line system than any specialty railcar mover manufacturers’ machine. Simply put; Caterpillar has the resources to produce a drive line system with durability, reliability, and product support that cannot be matched by any specialty mobile railcar mover manufacturer.

When the system is applied to the larger wheel loaders such as the Cat 950M or 966M the stability over the side increase as a result of a heavier base wheel loader.
