Triggering device for an emergency-activating valve on a hydraulic cylinder has a line for transmitting power and triggering an emergency-activating valve

摘要

Power for triggering an emergency-activating valve is made available by an autonomous power reservoir (4). A device (5) using muscular power makes this power available. A power-transmitting line (3) operates in a flexible manner and transmits electrical, pneumatic or hydraulic power. A power reservoir (4) is an electric, pneumatic or hydraulic power reservoir. An element like a switch, a throttle or a valve controls power transmission from the power reservoir into the power-transmitting line. Independent claims are also included for the following: (1) A hydraulic cylinder with an emergency-activating valve and a triggering device; (2) A lifting frame with a hydraulic lifting cylinder with an emergency-activating valve and a triggering device; (3) A construction/tip-up device like a mobile/tip-up excavator/truck.
