lever binders are equipped with a lever and a tension hook at each end. the lever amplifies the force applied when securing a load.

what are ratchet load binders?

ratchet binders use a ratcheting mechanism to create tension in the chain, ensuring the load is securely fastened. they feature a handle, two tension hooks, a cam, and a prawl mechanism that work together to produce a smooth, ratcheting action. compared to lever load binders, the handle of a ratchet binder requires significantly less pulling force.

when using a ratchet binder, the lever and screw collaborate to augment the force applied to the tie-down assembly, thereby tightly tensioning the chain and securing the load.

what are lever binders?

lever binders are equipped with a lever and a tension hook at each end. the lever amplifies the force applied when securing a load. however, they necessitate more pulling force because energy is stored in the handle. consequently, lever binders are considered the least safe option due to the accumulated tension in the lever upon release.

although lever binders allow for quick unbinding and unloading of cargo, ratchet binders are deemed safer due to their lower accumulated tension, which minimizes the risk of the bar snapping back.

can i use an extension bar to increase tension?

using an extension bar to increase chain tension is a hazardous practice. during the tightening and releasing processes, the extension bar can rebound rapidly and may even be propelled into the air, posing a significant safety risk.
