Pinet: Excellence in Hinge and Locking Solutions for Public Works Machinery

For years, Pinet has established itself as a leader in the design and manufacture of hinges and locking systems for public works machinery. With unique expertise and innovative manufacturing methods, Pinet offers high-quality, durable, robust, and aesthetically pleasing products that meet the stringent demands of this challenging sector.

Mastery of Rolled Metal Technique

At the core of Pinet's hinge manufacturing is the rolled metal technique. This method offers numerous advantages: 

• Cost Reduction: Rolled metal hinges are less expensive to produce than forged and machined parts. 

• Superior Aesthetics: Compared to welded parts, rolled metal hinges provide a more refined finish. 

• Increased Durability: They are particularly resistant to vibrations and harsh service conditions. 

• Adaptability: Pinet uses steel and stainless steel, with treated thicknesses up to 6 mm. 

• Customization Options: Possibility to add features to the hinge, such as an integrated spring or stop. 

• Ease of Attachment: The hinges can be easily fixed by screwing or welding. 

• Production Flexibility: Pinet can produce in small, medium, or large series, with simple manufacturing tools that allow for rapid prototyping.

Concrete Applications

Pinet's expertise results in high-precision and robust parts used in various public works machinery. For example, door hinges for cab loaders or backhoe loaders demonstrate Pinet's ability to provide reliable and high-performance solutions. In these applications, Pinet uses 5 mm thick raw steel sheets, which are cut, formed, and rolled through a semi-automated process. The hinges are then screw-fixed to the frame, mounted with the door, and painted along with the cab, ensuring perfect and durable integration.

Innovation and Customization

Beyond hinge manufacturing, Pinet also offers an extensive range of door and hood locking systems. The company excels particularly in creating custom-made parts to meet specific needs. For instance, Pinet designed a lock to reinforce an existing mechanism on public works machinery. This lock, consisting of a 4 mm thick steel support, zinc-plated and reinforced, a 16 mm square zinc-plated and reinforced steel bolt, and a stainless steel spring, ensures precise and play-free positioning thanks to a conical part engaging in a circular hole.
