Adopts ISO/V class (1000N/m㎡ or more). It is an amazingly long-life chain with wear resistance that is 3.5 times more than that of the manufacturer (compared to the manufacturer's ratio), with a wear rate of less than 1% even after long periods of hard use. It is also a special Zn anti-rust treated chain.
Equipped with a \"torque converter device\" which is a unique overload prevention safety mechanism. In the event of an overload, a safety slip is performed to maintain work safety and prevent a dangerous situation. This also prevents the hook from elongating and parts from being damaged, making it possible to extend the life of the main body and each part.
A ``impact-resistant gear case and frame'' with three stay bolts arranged on a ribbed steel plate, a ``high-precision gear'' with an integrated pinion shaft, and ``three dowel pins and bearings'' that properly hold the reduction gear against impact. , retains structural characteristics such as highly reliable \"mechanical wet brake\". In addition, it has a structure that strictly shuts out the intrusion of foreign substances such as rainwater and dust, such as \"double cover of the brake part\" and \"uniquely shaped chain guide\
