Q. Do power presses and press brakes need an examination? What are my responsibilities as a user?
These machines are used to work metal in a variety of industries from small metal fabrication companies to major car and engine manufacturers. Their capacity can range from small “bench” type presses at half ton to presses which impart 4,000 tons of pressure.
They are mechanically driven and, in the case of a power press, operate using a clutch and flywheel. A power press clutch is a device designed to impart the movement of the flywheel to any tool when required.
An important aspect related to power presses and press brakes is the guarding employed to protect the user. The type of guards can vary from fixed to movable to electronic or photoelectric devices and the type of guard determines how often presses are examined.
The Provision and Use of Work Equipment Regulations 1998 (PUWER) stipulate the type of examinations and tests required. The regulations place responsibilities on owners and users of power presses and press brakes to undertake a risk assessment of their operations and put in place measures to remove or reduce risk.
Users of these machines have significant responsibilities in the areas of training, maintenance and competence of users.
Regulation 32 of PUWER requires power presses and press brakes to be examined by a “competent person” and this examination should be completed at intervals dependant on the type of guards fitted to the press.
e.g. as a general rule the frequency is typically every 12 months for presses with fixed guards and at six monthly intervals for all others.
The examination and tests completed primarily seek to identify serious defects likely to cause an injury to persons using the machine or working in the close vicinity. They will also pick up on less serious defects which left unchecked could create a danger, along with a series of observations and comments.
