An axle suspension system is suited for a trailer including a trailer frame, an axle, and left and right wheels respectively connected on opposite ends of the axle. The axle suspension system includes a swing arm pivotably securable at one end to the trailer frame and connectable at an opposite end to the axle via a connector. The connector includes a bottom surface connected to the swing arm. A spring is connected at one end to the swing arm and is connectable at an opposite end to the trailer frame. A resilient pad may be secured between the bottom surface of the connector and the swing arm. In some arrangements, a track bar may be securable at one end to the axle and may be secured at an opposite end to the swing arm.

Implementations extend to a height adjustable single axle trailer. The trailer can be configured for efficient loading, transportation, and unloading of vehicles, such as side-by-side vehicles. In one implementation, the trailer's T-shape frame includes a longitudinal support with a latitudinal support (axle) affixed to the longitudinal support's rear end. The trailer further includes a hydraulic pump, a battery, and a remote control to operate the raising and lowering of the trailer. The trailer also features first and second suspension arms connected to the latitudinal support, each incorporating lower and upper housings, hydraulic rams, and springs housed within the lower and upper housings, thereby enabling flexible movement of the latitudinal support of the trailer. The hydraulic rams can be controlled to transition the latitudinal support between a lower loading position and an upper transport position.

A chassis that supports a scanning system that images core samples from a wellbore. The chassis provides a mounting base for the scanning system for transportation of the scanning system, and also while the scanning system is in use and stationary. A suspension system mounts between the chassis and wheels that facilitate transportation of the chassis. The suspension system isolates the scanning system from shock and vibration encountered by the wheels while transporting the chassis and scanning system. In an example the chassis is a trailer, and which is pulled by a tractor. Legs can telescope downward from the chassis and against the surface on which the chassis is disposed. Airbags are strategically located within the chassis that absorb the vibration and thereby isolate the scanning system from the shock and vibration. Locations of the airbags include paths of force transmission between the wheels and the trailer.

A suspension system for a trailer and associated methods are provided. In some embodiments, the suspension system includes (1) one or more first shock-absorbing components; (2) a second shock-absorbing component; and (3) a connecting member configured to position and connect the first shock-absorbing components and the second shock-absorbing component. The connecting member includes a supporting base configured to support the first shock-absorbing component. The connecting member includes a contacting surface member configured to be in contact with the second shock-absorbing component.

A low speed transport and docking system for a watercraft comprising a wheeled frame for supporting the watercraft and configured for transport over a land surface by way of at least one pair of ground engaging wheels and for docking the watercraft in and out of a body of water. The axle rotatably securing the ground engaging wheels to the frame comprises angled terminal end lengths such that the wheels are offset from the center length of the axle so that a winch system and locking mechanism together are operably connected to the axle for rotating the axle to adjust the height between the wheels and the frame such that the wheels are engaged with the ground while the frame height can be raised or lowered for transport and/or docking of the watercraft such that the watercraft can be docked in the water or on land and transported to and from water with a single system.

The present invention provides various devices and systems comprising a controller in connection with a first deployment mechanism to raise and lower a first lift axle on a wheeled vehicle, and in some cases a second deployment mechanism in connection with the controller for raising and lowering a second lift axle. A fail-safe mechanism is provided that automatically lowers the lift axle(s) if the controller is not receiving any electrical power.

A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two supports are slidably guided on the support base toward and away from each other. A wheel assembly is mounted to an end of each of the supports remote from the other support such that a distance between the wheel assemblies varies with movement of the supports on the support base. A locking device selectively locks each support to the support base in a first position where the wheel assemblies are furthest from each other and a second position where the wheel assemblies are closer to each other.

A locking mechanism configured to selectively secure a vehicle slider frame assembly to a vehicle frame assembly includes a locking member configured to move between a locked position and an unlocked position, an actuator shaft operably coupled with the locking member such that turning the actuator shaft along a longitudinal axis of the actuator shaft moves the locking member between the locked and unlocked positions, the actuator shaft including a first portion and a second portion that telescopingly engage one another and are releasably secured to one another, and a spring member positioned over the actuator shaft and configured to bias the at least one locking member toward the locked position.

The suspension system for a trailer is disclosed. The suspension system includes a torsion axle and an air spring operating to accommodate a wide range of a load weight applied to the trailer without any change in ride comfort. The air spring can be adjusted for its pressure inside to cover a heavy load weight, while the torsion axle can have relatively softer spring materials therein to cover a light (and zero) load weight. The air spring and the torsion axle are arranged in series to provide adequate suspension based on the load weight.

A suspension system for a trailer and associated methods are provided. In some embodiments, the suspension system includes (1) one or more first shock-absorbing components; (2) a second shock-absorbing component; and (3) a connecting member configured to position and connect the first shock-absorbing components and the second shock-absorbing component. The connecting member includes a supporting base configured to support the first shock-absorbing component. The connecting member includes a contacting surface member configured to be in contact with the second shock-absorbing component.
