Heavy Duty Block Type-PB -Single Sheave
The tough "Heavyduty Block" is reborn to be tougher.
-Strength is improved by using a double arm for the top and a rib structure for the main body. Based on a detailed strength analysis, the design was changed to improve the strength compared to the current model while preventing an increase in weight. Furthermore, the rotational stability is improved by doubling the shield bearing.
