A method for steering the wheel assemblies of a gantry crane, including the steps of beginning the steering of at least one wheel assembly in the desired direction; and setting the angular position of a moveable pointer indicating a theoretical position of the wheel assembly which is consistent with said desired direction. The following steps are also included: setting an increment value of the moveable pointer in a direction consistent with respect to the steering movement of the wheel assembly; calculating the angular difference between the angular position of the moveable pointer and the current position of the wheel assembly; andincreasing the increment value of the moveable pointer if the difference shows a decrease, or decreasing the increment value of the moveable pointer if the difference shows an increase.

A steering with shifting system for a camera dolly, including a steering column that can be connected to steering wheels of a camera dolly by first motion transmission means, the steering column being configured to rotate around its central axis in a plurality of positions from a central position to rotate the steering wheels by the first motion transmission means; a handlebar integrally connected to the steering column and configured to be moved to rotate the steering column in a respective position of the plurality of positions; a support body configured to contain the first motion transmission means, the support body including a bell-shaped sleeve coaxial to the steering column, the steering column being at least partly inserted in the bell-shaped sleeve and pivotable with respect to the bell-shaped sleeve; and a central position indication element configured to engage when the steering column is in the central position.

A transport vehicle includes a base, wheels connected to the base, and load receiving elements. At least two of the wheels have a track width therebetween in each of a transverse drive and in a longitudinal drive. The track width in the longitudinal drive and the track width in the transverse drive are each variable. The transport vehicle is transports a load having a longitudinal direction and a transverse direction between the wheels. The transport vehicle is drivable both in the transverse drive and in the longitudinal drive.

The disclosures herein generally relate to a vehicle and more particularly, to an all-terrain utility vehicle which can perform multiple operations, in varied terrain and soil conditions, with precision and guidance. An all-terrain utility vehicle mainly includes wheel track and wheel base adjusting system, a height adjusting system, a plurality of vertical axle assemblies, a steering system, an implement position adjusting system, a master controller unit and a plurality of wheel drive motors. All the vehicle functions being controlled and guided with the help of an electronic master control module which enables optional manual, remote and autonomous operations. The electronic master control module utilizes externally acquired location data and digital maps with soil and plant information for enabling precision field operations.

A steering control unit and to a method of controlling the steering of a multi-unit vehicle is provided, the vehicle having a plurality of vehicle parts movably connected to one another and a plurality of steerable axle units. A first axle control unit is in conjunction with a first steerable axle unit and at least one second axle control unit is in conjunction with at least one second steerable axle unit. The steering control system has a central control module that is connected to the axle control units via a common data line for exchange of steering angle data. The axle control units have data interfaces for communication via the data line. The data interfaces transfer mutually identical data formats, whereby the steering control system is set up in a modular manner with a variable number of axle control units that can be integrated.

A drill rig with a steering system may include a substructure having a wheelhouse, a drill floor arranged atop the substructure, a mast extending upwardly and above the drill floor, and a steering system arranged within the wheelhouse. The steering system may include a wheel assembly comprising an electric motor configured for driving rotational motion of a wheel, a deployment device configuring for deploying the wheel assembly to carry the drill rig, and a steering mechanism configured for selective engagement with the wheel assembly and rotating the wheel assembly.

The four-wheel steering system includes a front-wheel steering system that steers front wheels of a vehicle and a rear-wheel steering system that steers rear wheels of the vehicle in accordance with a steering angle that is a rotation angle of a steering wheel. The rear-wheel steering system includes a second ECU that, when the vehicle speed is equal to or lower than a vehicle speed threshold, performs antiphase control in which the rear wheels are steered in the opposite direction to that in which the front wheels are steered. When the vehicle speed is equal to or lower than the vehicle speed threshold, the second ECU performs in-phase control in which the rear wheels are steered in the same direction as that in which the front wheels are steered, in response to a specific trigger operation that is performed via the steering wheel.

The universal wheel includes a base member, a vertical axle, a lift member, and a wheel member. The lift member adjusts the universal wheel's height. A first driving element, a second driving element, and an engaging element are configured on the base member and the wheel member. The first driving element for turning the base member laterally within 360 degrees. The second driving element is for rolling the wheel member around its lateral axle. The engaging element couples or decouples an external shaft with the lateral axle of the wheel member. As such, through the first and second driving elements, and the engaging element, the universal wheel can control a height from the ground and can be rolled forward, laterally, obliquely, turned 360 degrees when standing in place, or in a combination of these operations.

A ground milling machine, in particular a road milling machine or stabilizer or recycler, having a machine frame and at least one front travel unit as viewed in a longitudinal machine direction and at least one rear travel unit as viewed in the longitudinal machine direction, each travel unit comprising a respective travel wheel, which is in contact with an underlying ground during travel operation of the ground milling machine and has a wheel tread configured for direct ground contact, or a crawler track, which is in contact with an underlying ground during travel operation of the ground milling machine, and a drive wheel configured for driving the crawler track, at least one travel unit being height-adjustable along a lifting axis via a lifting device and/or being rotatable about a steering axis for steering the ground milling machine, and the at least one travel unit being arranged on the machine frame via a mounting device, said mounting device being configured such that the travel unit can be moved at least partially transversely to the lifting axis and/or steering axis through a translational movement.

This invention relates to a drive module. The drive module includes a base and a steering assembly rotatably mounted to the base. The steering assembly is selectively rotatable about a predetermined steering axis and carries a drive train. The drive train is configured to provide a multi-stage drive reduction of the drive train and the drive train is adapted to support a wheel such that a centre of a contact patch of the wheel is laterally offset from the steering axis.
