초록 ▼

A remotely-controllable motorized toy vehicle having a highly-maneuverable skid steering system driven by single or dual motors, having a separately motorized lift device pivotally secured to the chassis of the vehicle operative to lift and transport transportable elements, and also having an automatic tow hitch mechanism. The lift and hitching mechanism is coupled to a motorized lift gear train which provides for the sequential actuation of the lift for lifting and transport of the transportable elements and acutation of the hitch mechanism for hitching and unhitching towed vehicles. The vehicle is constructed with a particular wheel track to wheel base ratio providing improved skid steering as well as enhanced manueverability and stability. The mechanisms and gear trains have proper ratios and dimensions providing for the proper sequence of hitch actuation during upward and downward movement of the lift device whereby the hitch is operative only upon extended upward operation of the lift. The remote central control device or station being capable of controlling a plurality of vehicles with control inputs from a plurality of operators.
