Provided herein is a split variable extension width self-propelled motorized transporter (SPMT) vehicle including a widening adaptor that allows for variable spacing of split SPMT trailers thus increasing the width of the loading platform without the need to add more SPMTs and Power Pack Units (PPUs).

A transport vehicle includes a chassis with at least two load carriers which are placed next to and at a distance from each other. The distance between the at least two load carriers are modifiable in order to modify the width of the transport vehicle. The at least two load carriers of the transport vehicle are connected to one another by at least one articulated twin-arm structure.

A modular heavy goods vehicle (10) comprises a left vehicle module (12) and a differently designed right vehicle module (14), each of which includes a longitudinal frame part (20, 24) and at least two wheel subassemblies (22, 26), and two transverse frame modules (16, 18) which extend in the direction of the width (B) of the vehicle and the free ends of which are releasably connected to the longitudinal frame parts (20, 24), the length of the transverse frame modules being adjustable.

An axle suspension has an axle support mounted in a swivel so as to rotate about an axis of rotation and a steering lever that is connected with the axle support in torque-proof manner and can be pivoted about the axis of rotation. The axle support accommodates at least one wheel axle and is mounted so as to be displaceable relative to the axis of rotation, in the wheel axle direction, on an adjustment path.

A trailer convertible between step deck trailer and flatbed trailer configurations includes a frame, wheel and axle assemblies supported on the frame, an upper deck at the front of the frame, a lower deck configured for vertical movement on a vertical slide rail from a first step deck position to a second raised flatbed position wherein the lower deck and the upper deck are coplanar; a controller actuatable for upward and downward movement of the lower deck; at least one locking support beam; and landing gear deployable to support the convertible trailer while it is parked for loading. An air lift jack assembly is configured to raise the lower deck, and an air pressure release valve is configured to release air pressure to lower the lower deck, in response to actuation of the controller. The wheel and axle assemblies may be configured for forward-backward movement and/or upward-downward movement.

The present invention may disclose a turbine fracturing equipment, including a transporter, a turbine engine, a reduction gearbox, a transmission mechanism and a plunger pump, wherein an output end of the turbine engine may be connected to one end of the reduction gearbox, the other end of the reduction gearbox may be connected to the plunger pump through a transmission mechanism; the transporter may be used to support the turbine engine, the reduction gearbox, the transmission mechanism and the plunger pump; the transporter may include a chassis provided with a transport section, a bearing section and a lapping section which may be connected in sequence; while the turbine fracturing equipment may be in a working state, the bearing section can contact with the ground, while the turbine fracturing equipment may be in a transport state, the bearing section may not contact with the ground.

In one or more arrangements, a trailer system is presented. In one or more arrangements, the trailer system includes a front wheel assembly having wheels and a rear wheel assembly having wheels. In one or more arrangements, the wheels of the front wheel assembly turn when the trailer is performing a turn and the wheels of the rear wheel assembly turn when the trailer is performing a turn. In one or more arrangements, the trailer system is configured to support an agricultural implement.

A trailer is disclosed with an extendable and retractable deck where the deck may be extended to hold two vehicles or two pieces of heavy machinery and also the deck may be retracted to hold only one vehicle or one piece of heavy machinery. This allows the user to travel with a smaller trailer, which is much more convenient and easier to travel with, except under the rare condition when the user is obliged to tow two vehicles or two heavy machines. The trailer uses a sliding frame rail system that is slidably attached to a stationary frame rail system. The trailer also uses a folding deck section system that extends and retracts like an accordion. The expanding and contracting frame systems used are a superior design that allows the trailer to carry and tow two pieces of extremely heavy equipment, i.e., two a bull dozers at one time.

A trailer assembly, including: (a) a frame sub-assembly, wherein the frame sub-assembly comprises a pair of rails adapted to support a pontoon/tritoon watercraft thereon; (b) at least two ground-engaging wheels, wherein the at least two ground-engaging wheels are associated with the frame sub-assembly; (c) a trailer coupler, wherein the trailer coupler is releasably securable to a trailer ball; (d) a rail drive sub-assembly, wherein the rail drive sub-assembly comprises a battery, an electrically powered hydraulic pump, at least two actuating hydraulic cylinders, and an up/down controller; and (e) wherein the trailer assembly is readily convertible between a raised position and a lowered position.

The present application pertains to a system comprising a multi-axle trailer with a front and a rear. The a multi-axle trailer comprises at least one lift axle configured to be raised or lowered to distribute weight, to increase trailer deflection during a turn, or both. A jeep is mounted between the trailer and a tractor wherein the jeep is configured to decrease weight on one or more axles. A booster is mounted to the rear of the multi-axle trailer. The system is configured such that during raising of the at least one lift axle an increase in air pressure to one or more other axles is increased to offset weight.
