Tractor drives, also known as trolley drives, bridge drives, bridge crane drives, hoist tuggers or even Lo-Hed drives, provide the push and pull to position overhead loads on a monorail or enclosed track. David Round's Railrunner™ products incorporate sleek design upgrades and beefy construction which distinguishes them from others. Our tractor drive products offer:

• Flexibility — we can provide drives for any size beam or rail. You are not tied into a special size.
• Highest horsepower rating — we offer from 1/2 Hp up to 2 Hp motors … the highest anywhere.
• Durability — place our drive next to any other manufacturer's drive and you can see what we mean. Everything is bigger, beefier, tougher. Our bearings are the heaviest duty in the tractor drive industry.
• More design options — We do specials! Call us for your unique applications or site-specific needs.
• Fast customer service — Tractor drives are not just a sideline for us. Your toll-free call (1-800-535-2725) will be answered promptly and knowledgeably.
