A substantial number of second-hand press presses have entered the market for used equipment due to bankruptcies or plant closings. As a result, manufacturers requiring additional press capacity or those looking to replace broken equipment are more often looking to the used equipment market as a bargain source for their needs. A majority of the equipment has security systems which are faulty and in violation of OSHA or ANSI standards. The majority of buyers don’t assess the safety system and are liable for significant, unexpected cost of purchase to upgrade their presses. When you’re considering buying an used press, be sure to be aware of the clutch/brake control system to ensure you budget your money appropriately power press machine. Safety for operators, OSHA 910.217 compliance, ANSI compliance as well as operational efficiency and cost are all important aspects to consider. To make matters more complicated, ANSI is set to announce its latest revision to ANSI B11.1 safety standards for mechanical press machines. There’s a rumor that OSHA might adopt one, or even all of updated and more strict ANSI language.
OSHA compliance isn’t the only factor in evaluating the effectiveness of the brake control. The buyer must take into consideration all of the possible uses for the device. Factors to consider: Available operating modes-off/inch/single/continuous are fairly standard; however, automatic single stroke, continuous on demand, or multiple operators may be required. Operator interfaces, displays with visuals and automated options are all part of the clutch/brake control system that impact the overall safety and efficiency. Do you require automated stop height, counterbalance controls, tonnage monitors, automated speed control, limit switches and protection for die?
There are a few simple things buyers might look for to establish the basic OSHA conformity:
Electrical schematics for the press were donated following June 1974.
- Air pressure switches for clutches and counterbalance.
- Mode control as well as stroke choice.
- Emergency stop in red and Yellow the top stop.
- Two-hand control, with anti-tie down option.
- Continuous prior action function (automatic presses).
- Control reliability-single component failure safe response
- Brake monitoring for hands in die operations.
- Dual safety valve for (hands in die operations).
