SUSPENSION BAR FOR HELICOPTER FOR MOUNTING WORKING EQUIPMENT

摘要

Arrangement in a bar, which is intended to hang down beneath a helicopter (1) or the like in order to carry equipment, such as saw equipment for tree lopping, which must be manoeuvred by the helicopter. The bar is designed so that if its bottom end is subjected to an upwardly directed compressive force, the said force is deflected or substantially attenuated before it reaches the upper end of the bar (5) connected to the helicopter (1). This prevents any upwardly directed force of harmful magnitude striking the helicopter as a result of the latter suddenly descending some metres.
