3 Roll Plate Bending Machines

A tri-speed electrical control package provides forward-neutral-reverse joystick operation, allowing operators to fine-tune roll speed for different material thicknesses and bend radii. This improves accuracy over single-speed manual drum controllers and reduces the risk of over-bending or material slippage during the rolling process.

Yes. Piranha-Bertsch offers a tri-speed electrical retrofit package compatible with earlier mechanical plate bending machines that use manual drum controllers. The retrofit upgrades the machine with reduced voltage control circuits, emergency stop devices, and a NEMA-12 rated enclosure to meet current safety standards without replacing the entire machine.

Standard safety features include two-handed operation requirements, front and rear emergency stop switches, safety mushroom switches, and reduced voltage control circuits. These features are designed to protect operators from nip point hazards and comply with OSHA safety codes and applicable electrical regulations.

A Machine Performance Audit is a service offered to evaluate the condition, safety, and productivity of an existing bending roll machine. The audit identifies maintenance needs and upgrade opportunities, and customers who complete an MPA receive discounts on replacement parts and additional labor for recommended retrofits or repairs.

3 roll plate bending machines are widely used in metal fabrication shops, structural steel fabrication, trailer and truck body manufacturing, and power and transformer production. Any operation that needs to curve or roll metal plate into cylindrical or curved components relies on this type of equipment.

Plate bending machines must comply with OSHA safety codes as well as applicable federal, state, and local electrical codes. This typically includes reduced voltage control circuits, properly rated control enclosures such as NEMA-12, and emergency stop devices positioned around the nip point area to protect operators.
