    As a WAG, they may be referring to the bomb carts with front and rear axles pulled by small tow tractors. I believe some had a steering linkage setup that when the front axle steered one way the rear steered the other, you could pull the whole train in a circle. Others were a kind of wagon steer. YMMV, I may be all wet.

    If you are talking about a heavy haul lowboy trailer with a rear booster/stinger axle group then you are referring to what people call a rear bump steer option. That is when you have hydraulic rams on both sides of the spreader bar with a self-contained pony motor to power the cylinders and allows you to hydraulically straighten the stinger axle group in a straight position in order to back up in a straight line. Now almost all pivot style stingers have a manual or air operated pin to lock the spreader bar in a straight position, but they are not engineered by the trailer manufacturer to be used when loaded, only unloaded.

    Hey there.

    Yeah, when this guy said bomb steer that is the only thing I can think of that makes any sense on a lowboy trailer. I couldn't find a pic of a Kalyn to use like the one you had.

    That's all I thought of too was bump steer. Who knows though.

    Not seen a steerable three axle jeep, pretty handy.

    Bump steer on a west coast trailer is handy. It'll help backing empty loaded, you can almost steer it like a full steerable trailer. Loaded is another story depending on how big the cylinders and pump is. I had a trailer like the red one, great empty and all but useless loaded. My Kalyn 13 had bump steer and it was bada$$. Giant cylinders and a 23 HP motor running hydraulics. The lighter setup only had 5.5 HP and the barrel of the cylinder was just slightly larger than the polish rod on the big setup......

    I was used to the old Load King drop necks and folding neck low boys, you all are so lucky.
