A retractable pallet fork carriage assembly is provided that enhances the safe operation of a lift vehicle, such as a loader or telehandler. A carriage assembly is coupled to a fork tyne assembly through scissor links that expand and retract the tynes relative to the carriage assembly. When the scissor links are closed, the fork tynes extend through the carriage assembly to receive a payload (e.g., a pallet). When an operator wants to remove the payload, the fork tynes retract while the payload is supported against the carriage assembly. In this way, the load remains in one stationary position while pallet fork tynes are retracted under the payload to release the payload. Various sensors generate and/or send signals to limit the operation of the boom lift, boom, and/or retractable attachment when a distance or load is out of a threshold range.

The present invention relates to ground support equipment for aerospace engineering, and particularly relates to an assembly and test operation robot for a space station experimental cabinet. The assembly and test operation robot comprises a mobile lifting platform, a comprehensive monitoring system, a rotating clamping mechanism, a multifunctional adapter and a science experimental cabinetet, wherein the mobile lifting platform is used for regulating the horizontal position and the height position of the science experimental cabinetet to realize assembly and transportation functions of the experimental cabinet; the rotating clamping mechanism is installed on the mobile lifting platform to realize clamping and rotation functions of the science experimental cabinet; the multifunctional adapter is installed on the rotating clamping mechanism to carry the science experimental cabinet; and the comprehensive monitoring system is used to monitor the assembly state of the science experimental cabinet in real time. The present invention realizes integrated operation functions of transportation, flipping, assembly and parking in the ground assembly and test process of the space station experimental cabinet, so as to achieve the purpose of safe, efficient and accurate assembly and test of the space station experimental cabinet.

A pivot frame assembly pivotably mountable in a fork-carriage apparatus includes: (a) a lower cross member; (b) an upper cross member; (c) a pair of laterally spaced apart first and second side members connecting the upper and lower cross members; (d) a fork assembly mounting shaft supported by the first and second side members; and (e) a reinforced central support member laterally intermediate the first and second side members and connecting the upper and lower cross members.

A fork-carriage apparatus for a lift truck includes: (a) a mounting frame assembly mountable to the lift truck for vertical movement; (b) a side shifter frame assembly slidably mounted to the mounting frame assembly; (c) a pivot frame assembly pivotably mounted to the side shifter frame assembly for translating therewith; (d) a fork assembly mounted to the pivot frame assembly for pivoting therewith; and (e) at least one load-pulling connector mounted to the pivot frame assembly and configured to connect a load to the fork-carriage apparatus for pulling the load.

A gripper for forklifts including a support frame that can be coupled to a forklift and a pair of jaws that are mounted on the support frame in a movable manner with respect to one another between at least one closing position and one opening position respectively for clamping and releasing a product to be transported and vice versa, wherein each jaw includes a support plate-shaped body that is coupled to a mounting body, which is in turn coupled in a movable manner to the support frame, wherein the support plate-shaped body includes a first face that faces the other jaw and a second face opposite the first face, a clamping panel that is supported by the support plate-shaped body to which it is connected with connecting members.

Reusable, flexible, lightweight, low cost flexible intermediate bulk containers (FIBCs) for the delivery of granular proppant material for fracing that will allow the transport of higher weights of proppant, such as sand, per truck load. The invention includes a container made of a high strength, flexible material with a top opening for loading and deploying the proppant. The container can be lifted and deployed with a fork truck or crane. Alternatively, proprietary deployment systems, such as a conveyor system, can be used to quickly and efficiently deploy the proppant from the container at a desired site.

A swivel base is provided on a trolley so as to be able to swivel around a vertical axis, and a fork can be slid in a horizontal direction between an advanced position and a retracted position by a sliding mechanism capable of moving up and down along a pillar erected on the swivel base. Thus, it is possible to realize a configuration in which an empty-box skid is loaded in one direction and unloaded in another direction by means of the swiveling swivel base, without employing a configuration in which a plurality of members is supported so as to be able to swivel around different vertical axes. A movable range of the sliding mechanism (a movable range of the fork) in a vertical direction is therefore not significantly limited, and a transfer position of the empty-box skid in the vertical direction can be set to a lower position.

A transportation apparatus includes a delivering device, an elevating unit and a loading device. The delivering device is horizontally movable. The elevating unit is disposed under and mounted to the delivering device, and is vertically extendable and contractible relative to the delivering device. The loading device is adapted for loading and unloading an object, and includes a moving unit and a fork unit. The moving unit includes a moving base horizontally movable along a lower first axis parallel to a first direction relative to the elevating unit. The fork unit includes two fork prongs being horizontally spaced apart from each other along a second direction which is transverse to the first direction.

A method and apparatus for rapid loading stacks of items aboard vessels which can include rotating palletized items to depalletize the items, and then placing the items on a lifting robot, lifting the robot and items into the hold of a vessel, removing the items from the robot using a load push lift truck, and then using the load push lift truck to stow the items in a stowage location. The empty robot can be removed from the hold of the vessel and put in a position to receive a another depalletized stack of cartons. In one option the robot has a plurality of fork channels for receiving the blades of a load push lift truck along with receiving the blades or a rotating lift truck.
