Ratchet strap mechanisms

Ratchet strap mechanisms are a range of components used to complete a flexible rigging element for securing cargo on a platform. They include:

1. Ratchet buckle.
2. End fittings (hooks, rings or special brackets).

Ratchet buckle

The mechanism has a ratchet design. The common name for the part is ratchet or ratchet handle. The operating principle is clamping a section of the strap. To tension it, the required length of webbing is fed through the opening of the mechanism: initial tension is applied by the operator’s muscular effort. After the end of the webbing is pulled through by the ratchet mechanism or a tensioning tool, the required tension level is reached and the strap is locked in the closed (folded) position.

Application areas

The ratchet mechanism is used:

1. As part of tie-down straps with hooks or rings.
2. To secure vehicle tie-down systems on platforms (automotive straps).

Mechanisms vary by load. Models are produced as standard for securing loads from 1500 kilograms to 10 tons. They are made of high-strength metal alloys, which increases reliability and service life.

To protect against UV radiation and other environmental factors causing corrosion, anodizing or zinc plating is applied.

How to choose

The choice of components is based on the tension level guaranteed by the equipment manufacturer. The strap may only be used in compliance with safety requirements. It is prohibited to exceed the load on the strap or mechanism components — this may damage the cargo units or injure personnel.
