A mobile robot transmission arrangement is provided herein. The mobile robot transmission arrangement comprises a movable actuator assembly and a transmission. The transmission element is movably connected to the actuator assembly such that the transmission element is guided in a vertical plane (z) by moving the actuator assembly in a horizontal plane (xy). The actuator assembly comprises one or more vertically tilted tracks, wherein the transmission element is connected to the actuator assembly by means of said one or more tracks.

Disclosed are various embodiments, aspects and features an oscillating track system that includes an oscillating track lock subsystem. The oscillating track system may include a track operable to rotate around a housing structure that is configured to receive an axle. While in operation, i.e. while the track is being rotated around the housing, the oscillating track system may be able to oscillate about the axle and, in doing so, incline or decline to accommodate undulating terrain. Advantageously, when stopped, the degree to which the oscillating track system has oscillated around the axle may be locked in place via an oscillating track lock subsystem comprised within the oscillating track system, thereby providing stability to the heavy equipment that includes the oscillating track system.

Improved lifting devices typically configured to move heavy loads to and from the cargo area or bed of an associated vehicle are disclosed.

The invention relates to a transport vehicle for transporting at least one transport unit. The transport vehicle including at least one drive unit having at least one electric drive, at least one steerable vehicle wheel, at least one standing platform, at least one control unit (6), and at least one loading fork, and at least two longitudinal outriggers, which are arranged parallel to one another and at a distance from one another and extend in a longitudinal direction of the transport vehicle and between which the loading fork is arranged so as to be height-adjustable and which are in each case connected to the drive unit by one end section and at the respective other end section of which in each case at least one non-steerable vehicle wheel is arranged.

A mecanum-wheeled vehicle (1), in particular for transporting a load, comprising a chassis (5) extending along a longitudinal axis (L) and a width axis (B) oriented perpendicular to the same, said chassis comprising at least four mecanum wheel drives (2; 2a to 2d) which can be controlled via control means (13) for carrying out an omnidirectional operation of the mecanum-wheeled vehicle (1), wherein the chassis (5) has a first chassis section (21a) with at least two (2a, 2b) of the mecanum wheel drives (2; 2a, 2b, 2c, 2d) and a second chassis section (21b) with at least two (2c, 2d) of the mecanum wheel drives (2; 2a, 2b, 2c, 2d). According to the invention, the first and the second chassis sections (21a, 21b) are arranged adjacent along a first adjustment axis (E1) and are mechanically connected to one another such that the spacing between same can be varied, and the spacing between the first and second chassis sections (21a, 21b) is adjustable along a first adjustment axis (E1) by controlling at least one of the mecanum wheel drives (2; 2a, 2b, 2c, 2d) of the first chassis section (21a) and/or of the second chassis section (21b) by means of the control means (13).

A transport device is for carrying and moving objects from one location to another. In an embodiment, the transport device includes a chassis and at least four motor-driven omnidirectional wheels arranged on the chassis. The chassis is configured to adapt the wheelbase and the track gauge of the omnidirectional wheels according to the size of the object. A corresponding method for operating such transport device is further specified in an embodiment. The embodiments of the application lie in the universal usage of the transport device for nearly all sizes and shapes of an object.
