The present invention relates to a method for determining the length of a demountable platform. In the method, a hooklift is used to lift the demountable platform from the ground onto a vehicle, magnitudes of one or more physical quantities related to a position of the hooklift are determined at a moment when the demountable platform comes into contact with rear rollers of the hooklift, and the length of the demountable platform is calculated based on the determined magnitudes of the one or more physical quantities and the position and orientation information of the hooklift relative to the ground. The present invention also relates to a system for determining the length of a demountable platform.

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.

The present invention relates to a transport device for a milling unit of a road milling machine, the milling unit comprising a milling drum box and a milling drum. Essential elements of the transport device include a support frame, a rotating device and a transport vehicle connector. The present invention further relates to a transport vehicle with a carrier vehicle and a transport device, as well as a method.

A movable modular truck toolbox mounting lift system for lifting and repositioning a modular accessory (e.g., toolbox, container, cooler, platform) of a vehicle (e.g., truck, UTV) to enable access to the modular accessory without requiring an entry into the vehicle, a vehicle storage area, or a truck bed. The system has driver side and passenger side support plates pivotably connected to a pair of arms, which are in turn pivotably connected to each other to and upon movement (extension) of one arm pair, the modular assembly transits up and backward within the storage area. The system may be operated via actuators and/or motors to rotate the arms and lift/reposition the modular accessory. The modular accessory may be a toolbox, cabinetry toolbox, or a tray for receiving a plurality of modular accessories. A method of installing and using the system to lift and reposition a modular accessory in a vehicle.

The invention is an apparatus and method for lifting objects onto the bed of a pick-up truck. The device includes (1) a rack assembly, (2) a swing arm assembly, and (3) at least one hydraulic arm. The invention can be optimized and adapted to fit on a standard pick up truck or a flat bed truck.

A method and an arrangement for optimizing load position in relation to a transportation vehicle, comprising a platform arranged to the transportation vehicle for receiving a load; an actuating device for moving the platform in relation to the transportation vehicle; a sensing device configured to generate a vehicle sensing signal and/or a non-vehicle sensing signal; a controlling device configured to receive at least one of the vehicle sensing signal and the non-vehicle sensing signal; generate controlling commands based on the received at least one of the vehicle sensing signal and the non-vehicle sensing signal; and transmit the controlling commands to the actuating device; wherein the actuating device is configured to receive the controlling commands and to move the platform in relation to the transportation vehicle based on the controlling commands.

Embodiments of the present invention include a method and system for blending multi-component granular compositions such as proppant used in hydraulic fracturing in well drilling. The system includes the control and management of an on-site storage system for each of the components, regulating the delivery of specified quantities of each component to a well site, and coordinating the flow of materials into and out of the blender.

Embodiments of the present invention include a method and system for controlling the flow rate of materials into and out of the blender. The system includes the control and management of an on-site storage system for each component of a mixture, regulating the delivery rate of a blend mixture into a blender hopper, regulating the exit rate of the blended mixture from the blender hopper, and coordinating the flow of materials into and out of the blender.

A hoist mechanism having an improved locking assembly. A hoist mechanism includes a frame including a first end and a second end, and the frame is pivotably coupled with a mounting structure at the frame first end. The hoist mechanism also includes a hoist arm assembly pivotably coupled with the frame second end, and the hoist arm assembly includes a jib operative to move between an extended position and a retracted position. The locking assembly includes a lug disposed on the jib and a link arm coupled with the frame. The link arm defines a slot dimensioned to selectively engage with the lug when the jib is moved from the retracted position. The hoist arm assembly is pivotable with respect to the frame when the jib is in the retracted position, and the frame and the hoist arm assembly are pivotable together when the jib is in the extended position.
