A ladder system includes a first rail, a second rail parallel to the first rail, a ladder bracket supported by and configured to slide along the first rail and the second rail, a ladder coupled to the ladder bracket and configured to rotate with respect to the ladder bracket between a lowered position and a storage position, and an air spring coupling the ladder to the ladder bracket and configured to apply a force to the ladder when the ladder is in the lowered position to keep the ladder in the lowered position. Another ladder system includes a rail, a bumper stop below the rail, a ladder bracket, a ladder, a bumper, and an air spring. An agricultural vehicle includes a chassis supported by a plurality of wheels, and a ladder system carried by the chassis. Related methods are also disclosed.

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.

A gangway comprises a fixed platform and a support structure connected to the fixed platform in a manner that allows the support structure to rotate with respect to the fixed platform between a raised stowed position and a lowered deployed position. A self-raising assembly is operative to rotate the support structure from the deployed position to the stowed position. The self-raising assembly includes at least one fluid actuated cylinder connected between the fixed platform and a distal end of the support structure. A raising actuator is usable by an operator to cause operation of the cylinder in a manner that rotates the support structure toward the stowed position.

A vehicle includes a vehicle body, a vehicle roof rack component and a vehicle ladder. The vehicle body has a roof body part and a side body part. The side body part defines a wheel well of the vehicle. The vehicle roof rack component is installed to the roof body part. The ladder is detachably installed to the vehicle body. The ladder extends from the roof body part and over the side body part to the wheel well.

A convertible roof rack is provided that is generally comprised of a light bar and a roof rack that is spaced from the roof of a vehicle. The roof rack is also rotatably interconnected to a support structure associated with the rear of the vehicle such that it is capable of moving from a first position of use adjacent to the roof to a second position of use away from the roof where the light bar remains interconnected to the vehicle adjacent to the windshield. As such, electrical connections associated with the light bar remain intact when the roof rack is rotated away from the roof.

A recreational vehicle satellite dish support incorporating a telescopingly segmented first arm having a proximal end, a distal end, and a lower surface; a fulcrum plate attached at the lower surface of the first arm, the fulcrum plate being positioned between the first arm's proximal and distal ends; an upwardly facing pivot stop fixedly attached to the first arm's proximal end; and a satellite dish mount fixedly attached to the first arm's distal end, the satellite dish mount including a telescopingly segmented second arm having upper and lower ends.

A Roof Top Rig is a kit which permits a user to erect a tent upon the top of a utility trailer. The device also provides for at least one fold down bed, at least one fold down table, at least one flip down seat and a portable solar panel. A plurality of electrical generation devices, household convenience devices, and plurality of electrical outlet and wireless communication systems may be included.

A foldable guard rail assembly for a chassis of a vehicle, such as, e.g., mining and excavation vehicles, is provided. In one form, the rail assembly includes at least one guard rail and two or more support members having an upper end pivotally coupled to the at least one guard rail and an opposed lower end pivotally mountable to the chassis such that the two or more support members and the at least one guard rail are configured to be raised and lowered relative to the chassis between a folded position in which the two or more support members and the at least one guard rail are folded relative to the chassis and an operable position in which the two or more support members extend proud from the chassis with the at least one guard rail extending therebetween.

A trailer-mounted power generation system that includes an enclosure having a roof, sides, end walls, and a floor adapted to be transported by a platform, and a generator positioned within the enclosure, the generator including an engine. The trailer-mounted power generation system also includes a ladder and fall arrest system.

A foundation construction machine includes a self-moving/mobile assembly moving the construction machine. An upper structure mechanically connected to the self-moving/mobile assembly has an access point allowing access to the upper structure, and equipped with a walkway surface for standing or walking. A mast/boom mechanically connects to the upper structure, whereon an operating equipment mounts for drilling the ground. A presence sensor integrally mounts to the upper structure to monitor a monitoring region integral with the upper structure and covering the walkway surface. The presence sensor detects presence of a solid body in the monitoring region and sends a detection signal representative of the presence. A control system connected to the presence sensor is configured for receiving the detection signal and for sending a control signal to cause the construction machine to execute a predetermined function(s) when the detection signal indicates presence of a solid body proximate the walkway surface.
