A fire apparatus includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a ladder assembly coupled to the chassis, and a stability system. The stability system includes at least one of (i) a front downrigger coupled to the chassis, (ii) a rear downrigger coupled the chassis, or an outrigger coupled to the chassis. The stability system is controllable to facilitate leaning the fire apparatus at least two degrees relative to a ground surface while maintaining full operational capability of the ladder assembly.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

The present invention relates to a trailer landing gear leg lock device that prevents the unauthorized retraction of a trailer landing gear leg to prevent a trailer from being stolen. The lock device is further comprised of two hinge-connected halves that can be placed around the landing gear leg of a trailer, wherein the halves can then be locked together via a locking mechanism. In differing embodiments of the lock device, the locking mechanism may be secured by a plurality of housings and compartments, as well a plurality of additional locks and lock covers. The device may further comprise a plurality of other theft resistant devices and accessories.

An apparatus has: a chassis; wheel assemblies at opposed sides of the chassis, each wheel assembly having: a ground engaging wheel; a wheel mount; a control arm pivotally connected between the wheel mount and the chassis; and an actuator pivotally connected between the wheel mount of the ground engaging wheel and the chassis; in which the actuator is operable to, in use, cause the ground engaging wheel to: pitch down with increasing camber from an upright position into a facedown position to lower the chassis; and pitch up with decreasing camber from the facedown position into the upright position to raise the chassis. A method involves lowering the chassis by operating the actuators to pitch the ground engaging wheels down into the facedown position; and raising the chassis by operating the actuators to pitch the ground engaging wheels up into the upright position.
