Abstract

A mobile deicer is mounted on hydrostatically driven wheels mounted directly to the longitudinal frame without springs, thereby increasing the stability of the apparatus. Supported on the frame is the unique body which allows stand up access to the engine compartment, carries a larger volume of deicing fluid, provides a crew compartment shielded from the weather, and provides ready access to the operator compartment. Supported atop the body and aligned with the longitudinal of the frame is the main boom, which raises and lowers the operators compartment. The operators compartment is connected to the main boom by a parallelogram boom which maintains the platform supporting the operators compartment in the horizontal plane. Also mounted on the platform is a scissor boom extendible horizontally which carries a nozzle on its distal end, the nozzle being positionable under the operators control. The scissor boom may be inclined relative to the horizontal plane within preset limits.

Dependent claims

Apparatus for deicing aircraft comprising, in combination:

(a) a ground vehicle having means for propulsion over the surface of the ground and a longitudinal axis wherein said vehicle has an enclosed internal crew compartment, a enclosed drivers compartment accessible from said crew compartment, and a closable door between the crew compartment and the exterior of said vehicle, said crew compartment and said drivers compartment being protected from external ambient weather conditions;
(b) a main boom mounted to said ground vehicle and aligned with said longitudinal axis, said main boom being mounted for selective movement about a horizontal pivotal mount at one end thereof atop said vehicle;
(c) a parallelogram boom mounted to said main boom at an end thereof opposite said pivotal mounting, said parallelogram boom being selectively positionable between a vertical position and a position displaced over 90.degree. from the vertical position;
(d) a platform supported on said parallelogram boom distal said main boom such that said platform remains horizontally disposed at all positions of said parallelogram boom;
(e) means for rotating said platform through 360.degree. about a vertical axis;
(f) an enclosed operator's compartment mounted on said platform for an operator to occupy, said compartment having an access opening cooperatively formed to define an entry way providing ingress and egress between the internal crew compartment of said vehicle and said operator's compartment without exposure to ambient weather externally of said vehicle when said operator's compartment is positioned adjacent an entry way opening into said crew compartment and said operator's compartment and means for closing said entry way when said operator's compartment is displaced from said vehicle by said boom;
(g) an extendible boom mounted on said platform and extendible generally horizontally therefrom;
(h) a positionable nozzle mounted on said extendible boom for directing a spray of deicing fluid therefrom under the control of an operator in said operator's compartment;
and,
(i) means for providing a supply of deicing fluid from within said vehicle to said nozzle.

7 more elements

Apparatus for delivering a fluid to a surface of a free standing object comprising:

(a) a platform supported by an articulated boom on a vehicle having means for propulsion over the surface of the ground and selectively positionable proximal said object and said vehicle wherein said vehicle has an enclosed internal crew compartment, an enclosed drivers compartment accessible from said crew compartment, a closable entry way between said crew compartment and said platform, and a closable door between the crew compartment and the exterior of said vehicle, said platform having an enclosed operator's compartment mounted thereon with a doorway permitting ingress and egress to said crew compartment when said platform is proximal said entryway;
(b) an extendible boom mounted on said platform for selective extension and retraction between a maximum extended position and a stored retracted position such that the length of the boom in its extended position is grater than 2.5 times its length in the retracted position;
(c) a positionable nozzle mounted on said extendible boom distal said platform;
and,
(d) means for supplying fluid from a remote source to said nozzle.
