Safety cylinders The challenge Lift, and maintain a load in any position. The solution A hydraulic cylinder protected by a 100% leak-free hydro-mechanical locking device, with double safety mechanism. The result Platforms which are much easier to manipulate: enhanced user comfort and optimized loading are the key to the success of this product. The applications Lifting tables, positionning of radar masts, suspension cylinders, car transporters…

Safety cylinders with mechanical locking The challenge Extend and block in position a landing gear actuator. Retract and block in position the same actuator. The result A landing gear with no triangle to block in position, capable of higher loads than classic cylinders. The solution A hydraulic cylinder designed, calculated and produced to aeronautical standards, and incorporating a mechanical ball locking device. The applications Landing gear actuators, safety locking devices, cylinders which need to be able to withstand higher mechanical loads than the hydraulic rating of the cylinder....

Locking optronic system for Rafale fighter aircraft The challenge Ensure components which are not shock resistant are locked into place on a fighter aircraft, when pilot gives appropriate signal. The solution A miniature hydraulic power pack designed to fit in the reduced space available, which activates three locking cylinders. The result Reliability of the aircraft control components, particularly challenging during landing phase on aircraft carriers. The applications Wherever extreme miniaturisation of electro-hydraulic components is necessary. © Dassault Aviation / F. Robineau c o m pl...

Oceanographic research instrumentation Oceanographic research buoys are an excellent application for HYDRO LEDUC know-how in the field of electro-hydraulic micro-components. This instrument includes a complete micro-hydraulic power pack comprising electric motor, piston pump, pressure relief valve, solenoid valves and accumulators. Designed to ensure the autonomous control of the research buoy. The function includes descending to a predescribed depth and returning again to the surface. Absolute reliability is critical to this application. The challenge The aeronautical / optronics locking...
