Apparatus for protecting the head of a person from an external force includes an inner shell which fits over the head of the person and an outer shell which fits over the inner shell. A plurality of bags which contain a pressurized gas are disposed between the inner shell and the outer shell. When an external force is applied to the outer shell some of the bags distribute and partially absorb the external force thereby reducing the force experienced by the person.

A suspension system for a steerable trailer includes a strut which is mounted to the frame of the trailer, an axle which is connected to the strut, and far and near suspension cylinders which connect the axle to the frame. The far and near suspension cylinders connect to opposite side of the axle. Steering rods connect adjacent axles together, the steering rod connection alternating between the left and right side of the frame.

An alignment method and system for connecting a tractor to a steerable trailer includes a connection roller which facilitates the connection by accommodating a variance in fifth wheel to kingpin alignment. The method and system also includes an alignment guide which visually assists the tractor driver in properly aligning the tractor to the interface member of the trailer.

A steering system for a tractor and trailer includes first and second sender cylinders which are turned 180&#xb0; with respect to each other, and first and second receiver cylinders which are turned 180&#xb0; with respect to each other. First and second front link members connect the first and second sender cylinders to a front equalizer arm, and first and second rear link members connect the first and second receiver cylinders to a rear equalizer arm. The pistons of the cylinders travel in straight paths experiencing no side loads, and each piston travels the same distance as the tractor turns with respect to the trailer.

A boom support vehicle for supporting elongated loads includes a front dolly which is pivotally connected to a rear dolly at an articulation point. The front dolly includes a front self steering castor axle, and a rear conventional axle. This combination of axles results in stability at high speeds, while also reducing the amount of scuffing which the boom support vehicle experiences as the transporting vehicle and the boom support vehicle negotiate a turn.

A carriage for transporting heavy loads on conventional roads is disclosed. The carriage comprises a central beam extending the length of the carriage and a plurality of cross beams. At least one of the plurality of cross beams comprises a hollow element having a first end and a second end, wherein the hollow element is coupled to and extends perpendicularly to the central beam; a first beam slidably positioned within the first end of the hollow element, wherein the first beam is coupled to at least one axle; and a second beam slidably positioned within the second end of the hollow element, wherein the second beam is coupled to at least one axle. The carriage further comprises a hydraulic system coupled to each of the plurality of cross beams for hydraulically sliding each beam positioned within each hollow element.
