Abstract
A toy workover rig modeling the kind used to service oil and gas wells. The workover rig includes a wheeled truck. An extensible mast is pivotally fastened to the truck. A remotely-controlled pivoting assembly is connected to the truck for selectively moving the mast from a horizontal, traveling position to a vertical, substantially perpendicular operating position. A remotely-controlled telescoping assembly is connected to the truck for selectively extending the mast from a retracted position to an extended position. A remotely-controlled hoisting assembly is connected to the truck for lifted selected objects within the mast.
Claims7
A toy workover rig, comprising:
- a wheeled truck having a body including a front and rear end and a midpoint therebetween, and a set of lateral opposing sides;
- an extensible mast having a top truss and bottom truss, said bottom truss being pivotally fastened to said truck;
- a set of extendible ground-engaging stabilizers connected at points proximate said truck midpoint and rear ends, and having a configuration adapted to prevent said truck from tipping when an extensible mast is pivoted upright and telescoped,
- wherein, said stabilizers include guide sleeves and arms,
- wherein, said set of stabilizers provided at the midpoint of body are center stabilizers having a configuration adapted to extend beyond said lateral opposing sides of said body;
- a remotely-controlled pivoting assembly being connected to said truck for selectively moving said mast from a horizontal, traveling position to a substantially perpendicular, operating position;
- a remotely-controlled telescoping assembly being connected to said truck for selectively extending said mast from a retracted position to an extended substantially perpendicular position;
- and,
- a remotely-controlled hoisting assembly being connected to said truck for lifted selected objects within said mast.
