## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The toy workover rig recited in claim 1, further comprising:
a tubing board pivotally connected to said top truss and having a configuration adapted to extend rearwardly from said top truss.

### Claim 3 (depends on 2)

The toy workover rig recited in claim 2, further comprising:
a rod basket being pivotally connected to said top truss and having a configuration to extend rearwardly from said top truss.

### Claim 4 (depends on 3)

The toy workover rig recited in claim 3, further comprising:
a work floor being pivotally connected to said bottom truss and including a plate having a pair of ground engaging legs hingedly fastened thereto.

### Claim 5 (depends on 2)

The toy workover rig recited in claim 2, further comprising:
a work floor being pivotally connected to said bottom truss and including a plate having a pair of ground engaging legs hingedly fastened thereto.

### Claim 6 (depends on 1)

The toy workover rig recited in claim 1, further comprising:
a rod basket being pivotally connected to said top truss and having a configuration to extend rearwardly from said top truss.

### Claim 7 (depends on 1)

The toy workover rig recited in claim 1, further comprising:
a work floor being pivotally connected to said bottom truss and including a plate having a pair of ground engaging legs hingedly fastened thereto.
