Cranes and Lifting Units
The cylinders used in lifting equipment must be designed in such a way that their weight is as low as possible. For this reason, welded constructions are mainly used, with piston rods made of tubes, often of special materials, which make it possible to reduce wall thickness while maintaining the required load limits. Particular attention must be paid to the welds, which are often inspected with ultrasound, as the breakage of a welded part can easily lead to very serious damage. HIDROMEC develops hydraulic cylinders and systems for hydraulic lifting equipment that are reliable, durable and in compliance with specific industry standards.
The most common types of applications for which we develop cylinders are:
Mobile cranes use cylinders with considerable dimensions, which have to meet the requirement of being as light as possible in order not to overload the crane structure.
The cylinders for these applications are welded and special attention must be paid to the welds, which are extremely critical as the breakage of a welded part would cause very serious damage.

Lifting platforms and lifting tables are devices that exploit the principle of the pantograph and can reach considerable dimensions with the help of hydraulic cylinders. The largest platforms are driven by two cylinders that must always work synchronously, which is a prerequisite for the uniform movement of the device.
Aerial work platforms are used to transport people to work at great heights. Hydraulic cylinders play a key role in these devices. These must be as light as possible and, above all, certified to the highest level.
Concrete pumps move the concrete stream to very high positions and consist of several booms, all moved by hydraulic cylinders.
The pump itself is equipped with two hydraulic cylinders that drive two pistons that push the concrete to the discharge nozzle. These cylinders are subjected to considerable loads and operate at high speed.
