Side hinges and locks: types, features and selection
Purpose and role of side hinges and locks
Side hinges and locks are important elements of fastening systems used in the construction of trailers, cargo platforms, containers and on-board vehicles. They ensure reliable fixation and hermetic locking of the sides, preventing their spontaneous opening during movement or loading.
Due to their design, these mechanisms can withstand significant mechanical loads, vibration and environmental influences. They play a key role in ensuring the safety of cargo transportation, helping to securely hold goods within the platform and preventing them from falling out on the road.
Types of side hingesSide hinges vary in design, material, and mounting method. They are most often made of steel, stainless steel or galvanized alloys, which ensures their strength and corrosion resistance.
By design, the hinges can be overhead or mortise. Overhead models are mounted on the outside of the sides and are used in most standard trailer designs. The mortise hinges are mounted flush with the surface, which provides a more aesthetic appearance and increased protection from mechanical damage.
Some hinges are equipped with a reinforced axle to extend their service life and increase load resistance. There are also models with a detachable design that allow you to quickly remove and install the sides without removing the fasteners.
Types of side locksSide locks are designed to securely lock and lock the sides in the closed position. They come in various types, including hook, lever, and snap mechanisms.
Hook locks consist of a metal hook and a counter bar, providing a simple and secure fixation. They are widely used in standard cargo trailers and low-tonnage transport bodies.
Lever locks have a complex design with a clamping mechanism that ensures a tight fit of the sides to each other. They are most often used in industrial and specialized cargo systems that require increased reliability.
Snap-on locks work according to the principle of automatic locking. They are easy to use and allow you to quickly lock the sides without additional adjustment. Such mechanisms are particularly in demand in areas where prompt access to cargo is required.
Materials and their impact on durabilityThe choice of the material of the side hinges and locks determines their resistance to external influences and service life.
Steel hinges and locks are highly durable and can withstand significant loads, but they are susceptible to corrosion. To protect against
