The main luffing cylinder is designed and manufactured to be mainly installed in provision crane, hose handling crane,

cargo pump room maintenance crane, life boat & rescue boat davit of general merchant ships (container ship, crude oil

tanker, liquefied natural gas carrier, and bulk ship) and equipped with cutting edge designs such as high corrosion

resistance and water repellency.

In particular, it is designed according to 3 levels of temperature, 0℃, -20℃, and -40℃, and all materials are used

according to each temperature after material test and tracked for management.

The inner part of cylinder is designed to have total different structure compared to other machines for ground use and

general industries; particularly, as impact load on the cylinder is increased according to the bearing of crane, the inner

part of cylinder should be equipped with low noise induction and high abrasion resistance; especially, the inner part

should be sufficiently strong to obtain safety of inertia force generated by spinning the crane.

After drawing approval and product inspection by the ship's classification organization, the products are delivered to

customers.
