1、Both sides of the hoist are covered with a thick steel gear case, processed with the highest level technology, and with a strengthened wheel cover.They have an ideal shape and rigidity to maintain bearing alignment and with stand external shock.
2、The braking mechanism is enclosed in a double cover. The wheel and the brake covers. These protective covers not only keep out weather elements but also help to prevent mud and dust from entering internal mechanisms.
3、In case one of Pawl spring is damaged, the other maintains its functions. This mechanism further increases sureness.Specially heat treated top and bottom hooks have enough strength and toughness for hard job.The design of the bottom hook, with relatively large dimensions, makes it easy to stabilize a load in proper position.
4、Use of unique ball and needle bearing remarkably increases mechanical efficiency and produces high output power with minimum manual input.
5、Chain guide mechanism in flanged load sheave and guide roller facilitate smooth movement of the load chain.
6、Stopper Prevents Excessive Lowering.
7、This is the special heat-treated load chain of Grade 80 whose tensile strength far suipasses JIS V class.
