Together with Liebherr, Weber-Hydraulik and Weber Rescue Systems have developed battery-operated pin-pulling cylinders for the straightforward construction and dismantling of lattice boom cranes.
The hydraulic pin-pulling cylinder is specially-designed with a fully-integrated battery-operated hydraulic unit for pulling and pushing connecting pins during the assembly or dismantling of cranes. Its internal electro-hydraulic drive means the cylinder is not tied to a power unit, and can therefore be used in a flexible and convenient manner. The movement of the cylinder is controlled via the remote control or with a rocker switch.
“When manufacturing rescue equipment, we are used to applying the maximum force to the minimum space. Our pumps are optimally designed for high pressures of this kind. In conventional industrial solutions, systems are used with significantly less pressure, and the cylinders have to be correspondingly larger,” explains development manager, Josef Eder of Weber.
Individual customer solutions
Weber-Hydraulik offers a wide range of different hydraulic components for mobile cranes. The challenge lies, among others, in the application-oriented development of sophisticated cylinder solutions. Some of these are equipped with additional functions, such as electronic displacement and force measurement, or position switches or various different valves and control elements.
For Weber Rescue Systems, offering individual customer solutions rather than standard systems is the declared goal. Wherever hydraulic applications are used for the purpose of pulling, pushing and cutting, the company houses a team with considerable experience in hydraulics.
The company’s flexible, dust- and spark-free cutting systems are of interest for applications in the dismantling of buildings, the recycling of vehicles and the lifting of heavy loads such as prefabricated components, bridge formwork or roof trusses. In the field of manufacturing, the flexible battery-operated devices are used to separate aluminium castings which are cast in multiple moulds, for example.
