A utility cart for maneuvering trailers and trailer accessories includes a base frame member, caster wheels mounted on an underside of the base frame member, a height adjustable hitch assembly, and a pair of handles extending upwardly from the base frame member. The hitch assembly is mounted to the central support members, and includes a vertical post extending upwardly from the support members and a telescoping frame member with a vertical sleeve that mates telescopically with the vertical post. The telescoping frame member includes a height adjustment mechanism that is operated by a hand crank, so that a user can turn the hand crank to raise or lower the height of the telescoping frame member. The utility cart may attach to trailers, trailer hitch accessories, or may be used as a docking station for the recreational vehicle loading and carrying apparatus set forth in U.S. Pat. No. 9,670,013.

A lift mechanism. The lift mechanism includes a base configured to support the lift mechanism in an upright position. A neck is upstanding from the base. A lift bracket is coupled to the neck. A coupling bracket includes a U-shape having a base and arms extending from opposing ends of the base. The base is coupled to the lift bracket. A linear actuator is configured to move the lift bracket up and down along the neck.

An aircraft jack and system is provided. The present aircraft jack may use electric, as opposed to hydraulic power. A scale may be incorporated into the jack to determine the lift load of the aircraft jack and a leveling device may be used to properly level the aircraft when lifted. A system of multiple jacks may allow the multiple aircraft jacks to communicate with each other and to synchronize movement electronically and automatically. A worm gear may also reduce the occurrence of collapse.

Examples includes systems and methods for lifting and moving gondolas using a modular gondola moving system. Components of a modular gondola moving system include interchangeable skates. The interchangeable skates are further removably attached to a longitudinal member which, when connected to the longitudinal member, form a skate system. Multiple skate systems are positioned to the underside of a gondola and may additionally be connected together by connector bars for stabilization and to form the modular gondola moving system. One or more lifting devices are provided independent of and are used in combination with each skate system for positioning the gondola on each skate system. The one or more lifting devices may be repeatedly used in order to place the gondola on a single modular gondola support system.

A unit for handling an aircraft turbojet engine includes a frame, a front cradle and a rear cradle designed for supporting the turbojet engine, and a plurality of electric actuators. The cradles include devices for securing the turbojet engine. The plurality of electric actuators includes three electric actuators, where a first one and second one are arranged opposite each other, on either side of a longitudinal axis of the frame, connected to the front cradle and arranged for moving same in vertical translation, and where a third actuator is connected to the rear cradle and arranged for moving the same in vertical translation. The handling unit further includes a device for rotary driving of the front cradle about a longitudinal axis of the turbojet engine.

Embodiments described herein related to a robotic system for transporting a container. The robotic system includes a lifting mechanism and a container storage assembly coupled to the lifting mechanism. The container storage assembly includes at least one bracket assembly that further includes a bracket elongated member. The bracket elongated member includes a surface having at least one slot and a locking mechanism within the at least one slot. The at least one slot and the locking mechanism are configured to slidably receive and positively lock at least one locking member of the container.
