This design was the basis for the current standard tilt body that usually has a flat roof. Less common since the advent of modern sliding roof systems.

A hand operated braking system to secure the trailer when at rest. Usually operates on one axle only.

Various hydraulic systems use hand pumps e.g. lightweight tippers and demountable body systems.

Pneumatic valve.

Hand-hydraulic systems have many uses e.g. ramps on low loaders, locking cylinders, etc. In particular the system is used for lightweight tipping bodies.

Animal transporters with multiple load decks may have a cable or chain suspended deck for small animals e.g. piglets, goats, etc which is hung below a main deck.

Animal carcasses are transported hanging from a cargo track under a vehicle roof.

Trailer for roll-on containers from the manufacturer Hüffermann.

Surface finish of garment carrying rails and tipping cylinders.

Used on the eyes of parabolic suspension and removes need for lubrication of wearing components.

Standard containers with removable solid roof for loading from above.

The hose connection system on tank vehicles e.g. petrol or oil tankers.

A special stainless steel alloy which is used for particularly aggressive products e.g. in tankers.

Maintenance free axle system from Daimler Chrysler/Henrickson.

Term used for wheel head.

Heating may be achieved by hot water or solar power e.g. for tankers carrying temperature sensitive cargo or box bodies for flower transport.

General term used for stronger than standard specification e.g. semi-trailers which are designed for use on poor road surfaces.

Heavy-duty turntables for long material vehicles.

Leading European manufacturer of lighting equipment for trailers.

Construction trailers may be fitted with hinged towing equipment that comprises both a 50mm eye and a 40mm eye which allows the trailer to be universally used with both heavy construction and normal trucks.

Military vehicles have an international trailer coupling which is different from the civilian standard. The military system (also known as a Nato coupling) comprises a hook that engages the trailer towing eye. This coupling system performs better off-road.

The standard height of the hook on lifting hook vehicles. The DIN standard height is 1570mm.

The hook lifting system is used with demountable containers that are pulled on or pushed off the vehicle chassis on rollers.

Telescopic vehicles have a hose pack that allows electric cables and hoses to be extended with the trailer.

Storage equipment (hooks or closed containers) for tanker discharge hoses.
