An upgraded version of the latest Heavyduty Block that has gained a good reputation in Japan as well as overseas for its high working load limit. During the design process, we conduct a strength analysis simulation, and confirm shapes using 3D printed samples before we actually start manufacturing. This brand new product has been developed while taking safety and reliability into consideration with various improvements such as the addition of two sets of steel bearings, which produces rotational stability.
■Material: Special stainless steel, Sheave pin/swivel/swivel pin/toggle pin: SUS304, Grease nipple: SUS303
*The working load does not apply to the becket part. *The working load conforms to the working load of the bearings. *This product contains two steel bearings with rubber seals.
A double arm for the top part and a rib structure in the center of the main body distributes the applied load and at the same time these features reduce and optimize the weight of the product. Forged parts are used for swiveling sections where strength is required.
The current model contains one set of shield bearings, whereas this new model has two sets. This helps the rotation stability of the sheave under heavy loads, and improves workability at sea.
To prevent the unintended release of the toggle pin, it can only be removed when it is aligned with the groove. The nut can only be turned when the double ring is pulled.
