QC70
Patent-pending solutions.
Up to 50% higher hydraulic flow compared to previous generation, thanks to improved design of the hydraulic couplings. Get better performance when using tools with high flow and low pressure drop requirements.
A specially developed, more durable nose seal in the hydraulic coupling dramatically increases service life and minimizes the risk of leakage. Nose seals are easily replaced without special tools.
Unique safety features keep tools in place even when hydraulic pressure is lost by, for example; the use of spring-loaded locking cylinders and the cylindric locking wedges that are terminated with a flat surface.
Encapsulated springs in the hydraulic coupling minimize the risk of contamination of the machine's hydraulic system in the event of spring fractures.
Improved design of covers and seals protects the couplings against dirt and contaminants.
Robust and unique design of hydraulic couplings.
