Any working environment where explosive gas, vapour or dust atmospheres may form must be equipped with explosion protected electrical, electronic and mechanical equipment, ie equipment that has an acceptable low risk of creating an ignition source. Two recent projects undertaken by Radio and Control highlighted the importance of this type of equipment. Conversion and certification […]

Let’s assume that a safety remote control is to be used to control the movements of a hydraulic machine. The risk analysis of the machine identified the necessity of a safety function to prevent a hazardous movement when the operator did not intend it, i.e. the UMFS safety function. The required performance level for […]

Safety electronics Two main global trends have become evident in recent years, and they are still influencing technical and technological decisions. On one hand, more and more electrical, electronic and programmable systems are integrated in all types of machinery, including lifting machines. This trend began some decades ago in the automotive sector, where systems like […]

Failsafe radio remote controls
Posted on by Radio and Control
As stated in the previous parts of this paper, the primary safety function of the radio remote control system must be the ability to bring the machine to a safe state. Protection of the Stop function against faults is therefore clearly critical. It should be noted, though, that protecting the Stop system is not enough […]

Safety is the principal requirement of any machine, and must be properly assessed and verified for each component. This is particularly important for machines such as cranes and hoists that typically operate above and around personnel, where uncontrolled motion could present many hazards. Of course, it is even more critical in the protection of […]

Posted on by Radio and Control
Introduction to safety radio remote controls In past years, radio remote control systems have become commonplace on lifting machines of all sizes. With such universal acceptance, users and purchasers of radio controls have come to regard them as convenient, safe and reliable. But in the global village of today’s marketplace it’s not always as simple […]
