Abstract

A power bender may be provided. The power bender may comprise a cart, a bender mechanism, and a scissor mechanism. The cart may have a zero turn radius. The bender mechanism may be configured to bend conduit. The scissor mechanism may be disposed between the cart and the bender mechanism. The scissor mechanism may be configured adjust a working height of the bender mechanism above the cart. The bender mechanism may be configured to rotate about a pivot point.

First claim

What is claimed is:

1. An apparatus comprising:
a cart having wheels wherein a wheel axis passes through the center of the wheels;
a bender mechanism configured to bend conduit wherein the bender mechanism is configured to rotate about a pivot point wherein a pivot point axis passes through the pivot point, the wheel axis and the pivot point axis being substantially parallel; and
a jacking mechanism disposed between the cart and the bender mechanism, the jacking mechanism configured to adjust a working height of the bender mechanism above the cart, the jacking mechanism configured adjust a distance between the wheel axis and the pivot point axis, the jacking mechanism comprising an upper arm and a lower arm pivotally extending in parallel between the cart and the bender mechanism.

2. The apparatus of claim 1 , wherein the bender mechanism is configured to rotate about the pivot point axis from a vertical working position to a horizontal working position.

3. The apparatus of claim 1 , wherein the bender mechanism is configured to rotate about the pivot point axis from a horizontal working position to a vertical working position.

4. The apparatus of claim 1 , wherein the bender mechanism is configured to rotate about the pivot point axis when the bender mechanism is fully raised.

5. The apparatus of claim 1 , wherein the bender mechanism is configured to rotate about the pivot point axis when the bender mechanism is fully lowered.

6. The apparatus of claim 1 , wherein the bender mechanism is configured to rotate about the pivot point axis when the bender mechanism is between a fully lowered position and a fully raised position.

7. The apparatus of claim 1 , wherein the cart has a zero turn radius.

8. The apparatus of claim 1 , wherein the bender mechanism is configured to bend the conduit comprising a diameter between ¾ inch and 2 inch conduit inclusively.

9. The apparatus of claim 1 , wherein the bender mechanism is configured to bend the conduit comprising one of the following: Rigid conduit, Intermediate Metal Conduit (IMC), and Electrical Metallic Tubing (EMT).

10. The apparatus of claim 1 , wherein the jacking mechanism comprises a scissor mechanism.

11. The apparatus of claim 1 , further comprising a conduit roller support.

12. The apparatus of claim 11 , wherein the conduit roller support is detachable from the cart.

13. The apparatus of claim 1 , further comprising a conduit roller support storage compartment.

14. The apparatus of claim 1 , wherein the pivot point is located near a center of gravity for the bender mechanism.

15. An apparatus comprising:
a cart having wheels wherein a wheel axis passes through the center of the wheels;
a bender mechanism configured to bend conduit wherein the bender mechanism is configured to rotate about a pivot point wherein a pivot point axis passes through the pivot point, the wheel axis and the pivot point axis being substantially parallel; and
a jacking mechanism, the jacking mechanism configured to adjust a working height of the bender mechanism, the jacking mechanism comprising an upper arm and a lower arm pivotally extending in parallel between the cart and the bender mechanism, the bender mechanism comprising;
a support deck,
a bending shoe,
a head unit, and
a power mechanism.

16. The apparatus of claim 14 , wherein the bending shoe comprises:
a first plurality of channels;
a first plurality of hooks;
a second plurality of channels; and
a second plurality of hooks.

17. The apparatus of claim 14 , wherein the power mechanism comprises:
a motor;
a gearbox;
a first chain;
a second chain; and
a shaft.

18. An apparatus comprising:
a cart having wheels wherein a wheel axis passes through the center of the wheels;
a bender mechanism configured to bend conduit wherein the bender mechanism is configured to rotate about a pivot point wherein a pivot point axis passes through the pivot point, the wheel axis and the pivot point axis being substantially parallel;
a jacking mechanism disposed between the cart and the bender mechanism, the jacking mechanism configured to adjust a working height of the bender mechanism, the jacking mechanism comprising an upper arm and a lower arm pivotally extending in parallel between the cart and the bender mechanism, the bender mechanism comprising;
a support deck,
a bending shoe,
a head unit, and
a power mechanism;
a conduit roller support detachable from the cart; and
a conduit roller support storage compartment.

19. The apparatus of claim 18 , wherein the bending shoe comprises:
a first plurality of channels;
a first plurality of hooks;
a second plurality of channels; and
a second plurality of hooks.

20. The apparatus of claim 18 , wherein the power mechanism comprises:
a motor;
a gearbox;
a first chain;
a second chain; and
a shaft.
