Hydraulics is the kind of power transmission which allows the greatest density of forces. There is no other kind of power transmission that will transmit comparable high forces with the same construction size. Hydraulic tools are a special type of power tools, which can be used for general assembly and repair jobs with preferably high force in lowest spaces. Simple applications, clearness of the program in line with robustness, short-term deliveries and universal operation possibilities have made Yale hydraulic components indispensible tools also for elaborate functions. The unlimited power of hydraulic tools is used in applications like lifting, levelling and positioning of heaviest loads, installations of machines, assembly of complex structures as well as in general repair of maintenance jobs. The components can also be operated in fixtures for clamping, testing, pressing, extracting, crimping, cutting, riveting and many more.
