Mobile Hydraulics
Mobile hydraulics applications cover a very wide range of mobile machines working in all kinds of environments, often under difficult operating conditions (operating outdoors, at the mercy of the weather) and in very dirty environments (grease and grease mixed with dust).
Whether it is a mobile crane lifting heavy loads, a construction machine, a tunnel boring machine or a demolition tong, they all have very high requirements for functionality and durability. Often, a robust design for the durable use of the machine must be combined with a simultaneous reduction in weight.
In all modern equipment, it is necessary to find sealing solutions that offer high static and dynamic sealing performance, low friction and suitable system guidance. HIDROMEC develops sealing systems for mobile equipment that are reliable, durable and comply with environmental standards.
The most common types of applications for which we develop cylinders are:
Deep drilling rigs and pile driving rigs are characterised by two cylinders that work together to hold the carriage of the drill in a vertical position as it drills into the ground.
These are cylinders of considerable length. When they are used in dusty environments, they require special scrapers to clean the rod appropriately.
Special earthmoving machines usually use cylinders with considerable dimensions, while excavator cylinders have all the characteristics of a mobile system, but the size of the cylinders is smaller.
Lifting equipment such as mobile cranes or concrete pumps are often equipped with cylinders whose basic characteristic is that they should weigh as little as possible. Therefore, welded constructions are mainly used, with piston rods made of tubes, often of special materials, which make it possible to reduce wall thickness while granting the necessary load requirements.
Particular attention must be paid to the welds, which are often checked with ultrasound, as the breakage of a welded part can easily lead to very serious damage.
This is equipment that converts construction debris into inert materials that can be reused in construction. First, the structures are demolished with crushing tongs, then the coarse debris thus obtained is pulverised with crushers into fine material that can be reused.
The cylinders for this type of application are often subjected to very high loads, so high-strength materials are used.

These are often imposing machines that drill through rock strata with a cutter driven by a series of cylinders of considerable size. These machines operate in extremely dusty environments, and the hydraulic components must be particularly efficient, as machine downtime is very costly. Linear position measurement with appropriate sensors built into the cylinder is often required.
High-quality cylinders tested with the utmost care and with very high-performance sealing systems are required, especially with regard to dust.

In the design of garbage trucks, special attention is usually paid to the strength of the components as well as the hydraulic cylinders, choosing materials that guarantee reliability and durability while optimising weight.
