Emergency stop configuration for ironworker
View Patent ↗One aspect is a hydraulic ironworker system having a hydraulic ironworker configured with hydraulic power to deliver controlled force to metal workpieces. An accessory tool is coupled to the hydraulic ironworker via a harness assembly and configured to receive the hydraulic power from the hydraulic ironworker. A remote pushbutton assembly is selectively coupled to the harness assembly and configured to control hydraulic power from the hydraulic ironworker to the accessory tool and further configured with an emergency stop button that, when actuated, disables all power to the hydraulic ironworker system. A safety plug assembly is configured to alternately couple to the harness assembly in place of the remote pushbutton assembly. Power to the hydraulic ironworker system is disabled until one of the remote pushbutton and safety plug assemblies are attached on the harness assembly.
1. A hydraulic ironworker system comprising:
a hydraulic ironworker configured with hydraulic power to deliver controlled force to metal workpieces;
an accessory tool coupled to the hydraulic ironworker via a harness assembly and configured to receive the hydraulic power from the hydraulic ironworker;
a remote pushbutton assembly removably coupled to the harness assembly and configured to control hydraulic power from the hydraulic ironworker to the accessory tool and further configured with an emergency stop button that, when actuated, disables all power to the hydraulic ironworker system; and
a safety plug assembly configured to removably couple to the harness assembly in place of the remote pushbutton assembly, wherein only one of the remote pushbutton assembly and the safety plug assembly is attached to the harness assembly at one time; and
wherein power to the hydraulic ironworker system is disabled until one of the remote pushbutton and safety plug assemblies is attached on the harness assembly.
2. The hydraulic ironworker system of claim 1 , wherein the hydraulic ironworker is also configured with an emergency stop button such that actuation of either the emergency stop button on the hydraulic ironworker or actuation of the emergency stop button on the remote pushbutton assembly disables all power to the hydraulic ironworker system.
3. The hydraulic ironworker system of claim 2 , wherein the emergency stop button on the hydraulic ironworker is in series electrically with the emergency stop button on the remote pushbutton assembly.
4. The hydraulic ironworker system of claim 1 , wherein the accessory tool comprises one of a pipe bender, a shop press, a radius roller, a horizontal press, a brake press, a plate shear, a plate roller, a slip roller, a welding positioner, a power hammer, a power shrinker/stretcher, a planishing hammer, a power bead roller, and an automotive lift.
5. The hydraulic ironworker system of claim 1 , wherein the remote pushbutton assembly comprises controls for putting the ironworker into an iron worker mode, an accessory mode or an auto cut mode.
6. The hydraulic ironworker system of claim 1 , wherein the emergency stop button of either the hydraulic ironworker or the remote pushbutton assembly comprises a twist lock mushroom head that opens a circuit when depressed.
7. A hydraulic ironworker system comprising:
a hydraulic ironworker configured with electric power and with hydraulic power to deliver controlled force to metal workpieces;
an accessory tool coupled to the hydraulic ironworker via a harness assembly and configured to receive the electric power and the hydraulic power from the hydraulic ironworker, wherein the electric power from the hydraulic ironworker is delivered to the accessory tool via the harness assembly as an open circuit;
a remote pushbutton assembly that, when coupled to the harness assembly, closes the open circuit thereby enabling control of the hydraulic power from the hydraulic ironworker to the accessory tool, wherein the remote pushbutton assembly is configured with an emergency stop button that, when actuated, disables all power to the hydraulic ironworker system; and
a safety plug assembly that, when coupled to the harness assembly, closes the open circuit, wherein only one of the remote pushbutton assembly and the safety plug assembly is attached to the harness assembly at one time; and
wherein power to the hydraulic ironworker system is disabled until one of the remote pushbutton and safety plug assemblies is attached on the harness assembly thereby closing the open circuit.
8. The hydraulic ironworker system of claim 7 , wherein the hydraulic ironworker is also configured with an emergency stop button such that actuation of either the emergency stop button on the hydraulic ironworker or actuation of the emergency stop button on the remote pushbutton assembly disables all power to the hydraulic ironworker system.
9. The hydraulic ironworker system of claim 8 , wherein the emergency stop button on the hydraulic ironworker is in series electrically with the emergency stop button on the remote pushbutton assembly.
10. The hydraulic ironworker system of claim 7 , wherein the accessory tool comprises one of a pipe bender, a shop press, a radius roller, a horizontal press, a brake press, a plate shear, a plate roller, a slip roller, a welding positioner, a power hammer, a power shrinker/stretcher, a planishing hammer, a power bead roller, and an automotive lift.
11. The hydraulic ironworker system of claim 7 , wherein remote pushbutton assembly comprises controls for putting the ironworker into an iron worker mode, an accessory mode or an auto cut mode.
12. The hydraulic ironworker system of claim 7 , wherein the emergency stop button of either the hydraulic ironworker or the remote pushbutton assembly comprises a twist lock mushroom head that opens a circuit when depressed.
