Systems and methods for loading a container onto a container carrier comprising, lowering a set of rails of the container carrier from a raised position to a lowered position, wherein a horizontal surface of each of the set of rails is lower than the bottom surface of the container, expanding, horizontally, the set of rails, to an expanded position, moving at least one of the container carrier or the container so that the container is between the set of rails, contracting, horizontally, the set of rails, to a contracted position, such that the horizontal surface of each of the set of rails is directly underneath the bottom surface of the container and raising the set of rails from the lowered position to the raised position, such that the horizontal surface of each of the set of rails lift the container off the supports.

The aircraft transport trailer enables the loading, transporting, and unloading of a helicopter. The transport trailer comprises a wheeled trailer having a power unit, a height adjustable roller platform having a first position for loading or unloading the helicopter and a second position for transporting the helicopter, and a winch for moving the helicopter, the winch being power driven, the winch pulling the helicopter forward and releasing backward, a strap assembly being connected to the winch, and a pair of micro-switches positioned upon the trailer in cooperative engagement with the winch. Each micro-switch is positioned upon the trailer proximate to a cushioned bumper and to a towing position for the helicopter. The pair of micro-switches cut the power to the winch as the helicopter skids or wheels touch the micro-switch thereby properly positioning the helicopter upon the platform of trailer for when the trailer is raised to the second position.

A trailer system and method of use for towing a load are provided. The trailer system include a trailer body supported by suspension arms on a trailer frame. A hoist mechanism having a winch device and a flexible connector can raise and lower the trailer body by swinging on the suspension arms, which maintain the trailer body in a substantially horizontal orientation during the swing. A modular wheel suspension can be attached to the trailer system.

A vehicle lowering system is provided having a movable arm that is connected to a vehicle through an upper link and a lower link. The upper and lower links pivot with respect to the vehicle on pivot points on one end and pivot with respect to the arm on pivot points at the opposite end. The spacing of the pivot points and the length of the upper and lower arm create an instant center, about which the movable arm pivots. An actuator is connected to the vehicle on one end and the movable part of the suspension on the opposite end. The actuator is movable between an extended and a retracted position. When the actuator moves between the extended and retracted position, the movable arm moves the vehicle between a raised and a lowered position.

A bed height adjustment system for adjusting height of a bed of a vehicle including an air spring supporting the bed; a valve unit connected to an air tank and configured to adjust height of the air spring by supplying and discharging air; and a vehicle-control ECU provided with a dump-signal line and a return-signal line each connected to the valve unit. The valve unit adjusts the height of the air spring into a dump mode by inputting a signal of the dump-signal line, returns the height of the air spring into a normal mode by inputting a signal of the return-signal line, and maintains the dump mode or the normal mode when the signal is not input.

A bed height adjustment system for adjusting height of a bed of a vehicle includes: an air spring supporting the bed; a valve unit connected to an air tank and configured to adjust height of the air spring by supplying and discharging air; a relay provided with a dump-signal line and a return-signal line each connected to the valve unit; a pressure switch configured to be switched between an ON state and an OFF state based on whether air is supplied from the valve unit; and an indicator that becomes illuminated state when powered when the pressure switch is in the ON state and becomes non-illuminated state when the pressure switch is in the OFF state.

A lowerable vehicle frame with a folding trailer hitch for trailers and other vehicles has a vehicle frame, which can be transitioned between a lowered transit position and a raised deployed position through a swing suspension assembly and a plurality of lifting devices. A folding trailer hitch connected to the forward end of the vehicle frame allows the vehicle frame to be towed, and folds upwards for storage and aesthetics.

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.

A warehouse robot configured for automatically loading storage locations of a warehouse with containers, the warehouse robot including a plurality of electric motors; a horizontally oriented loading surface arranged at a topside of the warehouse robot and configured to receive a container of the containers; a plurality of motor rotatable wheels arranged at a bottom side of the warehouse robot and configured to move the warehouse robot on a ground, wherein rotation axes of the wheels are respectively oriented parallel to the loading surface, wherein first wheels of a first group of the wheels are synchronously oriented in a first driving direction, so that the warehouse robot is drivable in the first driving direction on the ground by motor driving the first wheels, wherein second wheels of a second group of the wheels are synchronously oriented in a second driving direction that differs from the first driving direction.

A trailer system and method of use for towing a load are provided. The trailer system include a trailer body supported by suspension arms on a trailer frame. A hoist mechanism having a winch device and a flexible connector can raise and lower the trailer body by swinging on the suspension arms, which maintain the trailer body in a substantially horizontal orientation during the swing. A modular wheel suspension can be attached to the trailer system.
