The present disclosure is directed to the transport of one or more loads of items including building materials and/or other items to one or more target surfaces including one or more elevated surfaces. The present disclosure is also directed to the holding of one or more loads of items including building materials and/or other items during transport to one or more target surfaces including one or more elevated surfaces. The present disclosure is also directed to the holding of one or more loads of items including building materials and/or other items on one or more target surfaces including one or more elevated surfaces.

A closed strap collar for securing cargo by friction, a device for lifting cargo and a lifting method, the collar being formed by a strap and a tensioner which, by tightening the strap around an element, allows cargo to be secured to the element being held or the held element to be raised by pulling the strap collar.

Disclosed are various embodiments for a trailer stacking device that makes use of multiple masts featuring support platforms that are capable of lifting and lowering a trailer vertically during trailer stacking operations.

Disclosed is a method and apparatus for transferring a plurality of cargo units, each cargo unit having a cavity therein, providing a lifter suspended in free floating form by a crane, the lifter having a frame and at least one lifting arm which is detachably connected to the frame wherein the frame has at least one lifting connector for detachably connecting the lifter to the crane; moving the lifter to a position immediately adjacent the plurality of cargo units; causing each free end of the at least one lifting arm to penetrate at least one cavity of one of the plurality of cargo units; raising the at least one of the plurality of cargo units to an elevated position; moving the lifter and the at least one raised cargo unit to a second position laterally spaced from the original position wherein each free end of the at least one lifting arm is elevated compared to each second end of the at least one lifting arm; and depositing the raised cargo unit at the second position.

It is intended to easily perform a work concerning lifting of the crawler. A crawler frame has a crawler frame outer surface that is opposite to a surface via which the crawler frame is attached to a traveling body main part in the left-right direction. A bracket includes an attaching part, a circuitous part, and a crawler lifting section. The attaching part is attached to the crawler frame outer surface. The circuitous part is partially arranged below and above a crawler belt on an outer side thereof in the left-right direction, and extends around the crawler belt. The crawler lifting section is connected to the circuitous part and arranged above the crawler belt for receiving the crawler lifting tool.

A structure installation system which maintains one or more walls in a desired position and orientation during installation of the one or more walls. The structure installation system generally includes a vehicle which is adapted to traverse a ground surface. The vehicle includes an arm having an arm coupler to which a support is connected. One or more walls adapted to be installed in the ground surface may be removably connected to the support, such as by securing the walls to adjustable hangers that are removably connected to the support. By adjusting the positioning of the hangers, the orientation and position of the walls may be adjusted. Once put in position, the vehicle and support will retain the walls in the desired position and orientation while concrete is poured and allowed to cure to form a unitary structure such as a bollard wall.
