A dock edge, also known as a dock bumper or dock fender, is a piece of equipment installed at the edge of a loading dock to absorb the impact of a truck or trailer during loading or unloading operations. Dock edges are designed to protect both the loading dock and the truck from damage that can occur from contact during these operations.

Dock edges are typically made of durable materials such as rubber, steel, or plastic, and are available in a variety of sizes and shapes to accommodate different types of trucks and loading docks. They may be mounted vertically or horizontally, depending on the specific application and the type of equipment being used.

The most common types of dock edges are:

1. Laminated dock bumpers: These consist of layers of rubber or other materials that are laminated together to provide additional strength and durability.
2. Molded dock bumpers: These are made of a single piece of rubber or plastic and are designed to absorb the impact of a truck or trailer during loading and unloading.
3. Steel-faced dock bumpers: These consist of a steel plate that is mounted to a rubber or plastic bumper, providing additional protection against heavy impact.

Dock edges are an important safety feature for loading docks, helping to prevent damage to both equipment and personnel. Proper maintenance and regular inspections are necessary to ensure that dock edges operate safely and effectively. This includes regularly inspecting for signs of wear or damage, and promptly repairing or replacing any damaged or worn components.
