Described herein are systems and methods for using different truck types for deliveries. A package is initially loaded into a specially configured cargo container that can be transported either on a primary truck or a secondary truck. A secondary truck is smaller than a primary truck and is configured to transport fewer cargo containers than the primary truck. An initial leg of the overall delivery (e.g., from a warehouse to a transfer point) is performed using a primary truck. The cargo container is then transferred to a secondary truck, which completes the delivery. Empty cargo containers can be transferred back to a primary truck, e.g., in a stacked or folded manner, for transporting back to the warehouse. The configurations of primary and secondary trucks are such that these transfers can occur at any location (e.g., a parking lot) with minimal human involvement.

A device for moving a load is provided. The device includes a platform defining a surface and an edge extending downward therefrom. The device further includes two pairs of opposing legs each defining a top portion pivotally engaged with the platform interior of the edge, wherein each pair of legs has an extended position where each leg extends away from the edge. Each pair of legs further includes a collapsed position where the top portion of each leg extends substantially parallel and interior to the edge, a middle portion of each leg extends through a corresponding slot defined by the edge, and a bottom portion of each leg extends substantially parallel and exterior to the edge.

A locking mechanism has a guide and a vertically movable plate. The plate is movable in the guide under gravitational influence between a locked position and an unlocked position. A slot is formed in the plate to receive a guide pin. The guide pin maintains the movable plate in the guide. The slot enables axial vertical movement of the plate in the guide. The plate moves into the locked position upon contact with a surface. In this position, the plate projects from the guide to lock a roll off container onto the hoist. The movable plate reverts to the unlocked position upon removal of the surface so that the plate moves into the guide.

A collapsible trunk for use with a vehicle having a wheel well. The trunk comprises a base wall and a side wall pivotally connected thereto. The side wall extends from the base wall and terminates at an upper edge. The side wall and base wall collectively define a storage cavity. The base wall and the side wall each have an expandable portion conformable to the wheel well in response to placement of the base wall and the side wall over the wheel well. The trunk is selectively transitional between a collapsed configuration and a deployed configuration. In the collapsed configuration, the base panels overlap each other, and in the deployed configuration, the plurality of base panels are co-planar to each other. The upper edge of the side wall moves away from the base wall as the trunk transitions from the collapsed configuration toward the deployed configuration.

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.

Methods and systems are provided for loading and unloading an item onto a vehicle. In one embodiment, a system includes: a loading system configured to receive a locker configured to store the item; a shuttle transfer system configured to transfer the locker to a storage position within the vehicle; and a swing arm system that couples to the loading system and the shuttle transfer system, the swing arm system configured to adjust a position of the loading system relative to the vehicle.

A power pack is located within a housing on the platform of a wind turbine generator tower. The power pack is supplied from a fuel tank. With the door of the housing open, the power pack may be removed for servicing and repair by using a U-shaped support structure to which an electric motor is mounted. Two support rails permanently located within the housing support the housed power pack. A chain attached to the power pack is driven by the motor to remove the power pack from the housing by sliding the power pack along the support structure. A pulley arrangement reduces the necessary torque. After removing the power pack from the housing, a crane is used to lift the power pack from the platform and to lower it down to a sea vessel. The crane may also be used in the refilling of the fuel tank by hauling a fuel line from a sea vessel up to the platform and connecting it to the fuel tank.

A vehicle, equipment for loading a load carrying device onto the vehicle, and a sensor that determines a deviation angle between longitudinal axes of the vehicle and load carrying device. A control compares the deviation angle to a maximum deviation angle, and if less than maximum deviation angle a loading procedure is performed, which procedure includes engaging a loading tool with an attachment part at an end of the load carrying device; lifting the end by the loading tool while another end of the load carrying device is on the ground; adjusting the vehicle position to decrease the deviation angle while the working equipment lifts the end of the load carrying device; monitoring the deviation angle during adjustment, comparing the deviation angle to a threshold deviation angle, and moving the load carrying device onto the vehicle in response to the deviation angle being less than the threshold deviation angle.

Methods and systems are provided for loading and unloading an item onto a vehicle. In one embodiment, a system includes: a loading system configured to receive a locker configured to store the item; a shuttle transfer system configured to transfer the locker to a storage position within the vehicle; and a swing arm system that couples to the loading system and the shuttle transfer system, the swing arm system configured to adjust a position of the loading system relative to the vehicle.

The invention relates to a loading arm assembly for a load-handling vehicle, having a main arm, having an auxiliary arm, and having a gripping hook, wherein the loading arm assembly is configured for unloading and loading transportation containers having a hook, wherein a pivot arm part is disposed on the auxiliary arm so as to be pivotable by way of an articulation, wherein a gripping hook is disposed so as to be pivotable on the pivot arm part. The loading arm assembly is improved in that the pivot arm part in a transporting position engages in a clearance of the auxiliary arm.
