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.

A self-trailering grain bagging machine on four wheels for storing grains and seeds inside a silo bag. The machine has a grain receiving hopper within which a compression auger encased in an auger tube. The auger is driven by mechanical means powered from a tractor's power take-off. The machine is mounted on a frame fitted with paired crossmembers at its left and right hand sides. Each crossmember is mounted upon a pair of wheel supports. The wheel supports are capable of gyrating relative to the crossmembers. The wheel supports carry one wheel that wheel rotates along with said wheel support. A work tongue is attached to the front side of the frame. The work tongue pivots relative to a horizontal axis. A transport tongue is attached to one crossmember wherein the wheels remain aligned in the direction intended for work and when turning said wheel supports by 90 degrees.

A mobile crane, such as a crawler crane, including an undercarriage having a chassis and a superstructure rotatably supported on the undercarriage and having a pivotable boom. At least two platforms are permanently arranged at the superstructure via which the superstructure is walkable. The platforms each comprise a base and a railing that are movable from a transport position in which they contact the superstructure into a work position in which the bases are walkable and are secured by the railings, and vice versa.

An intermediate support holder includes right and left guy line retaining units, right and left intermediate support line retaining units, and a connecting unit. The intermediate portions of the guy lines can be attached to the guy line retaining units. The intermediate support line retaining units are disposed so as to be aligned in the right-left direction with respect to the guy line retaining units, and base end portions of the intermediate support lines can be attached to the intermediate support line retaining units. The connecting unit couples and fixes the pair of right and left guy line retaining units and the pair of right and left intermediate support line retaining units to each other.

A crane fall protection system is disclosed herein for use within building or construction sites. The system may comprise a safety net and an adjustable scaffold structural member. The adjustable scaffold structural member may be provided as a deployable arm that extends from the side of a crane. In some embodiments, the system may include an access flap that enables an operator to access a ladder of the crane without removing the safety net. In some embodiments, one or more tension wires may extend from the safety net and/or the scaffold structural member and attach to a pad positioned underneath an outrigger of the vehicle to provide additional support for the safety net. In some embodiments, air inflatable units may be used instead of a safety net. In some embodiments, connections to outriggers may be used to suspend the safety net instead of a scaffold structural member.
