ABSTRACT:
A service cart transportable in a van or truck is comprised of a vertically oriented pyramid-shaped profile. The pyramid shape offers a high degree of stability, making it virtually impossible to tip over during normal operating conditions, especially during transport. The cart has a fourwheel base. One set of wheels is preferably swivel casters for turning sharp corners. A second set of wheels is larger and located externally of the cart. These wheels increase the base of the pyramid profile and add to the cart's stability. The service cart may be transported to and from a job site. The cart fits into a van or truck bed. To remove the cart from the vehicle, a ramp system is provided. A mechanical or electrical winch may be used to transport the cart into or out of the vehicle.
