The Blue Danube series is a bi-directional crane developed by Yongtian, whose concept and technology are far ahead of its domestic competitors.
This series of cranes is easy to operate and easy to work safely at high altitude：
1. any height can be lifted,no height limitation.
2. pendulum load lift in both direction,allows you to achieve 50% efficiency increases.
3. quick and flexible assembly of Kernmantle rope,simple operation for working platforms.
4. multi-function,rise of pulling force by using block and tackle hoisting,can be as traction-electric -hoist.
5. easier installation with 360 rotate hanging hook.
6. easer installation of load hook and hook terminal,quickly ready for use.
7. simple hoisting materials without rolling the rope up.
8. much higher speed max.25m/min than traditional electric hoist.
There are two types of Bi-direction rope hoist, which are divided into material rope hoist and steel rope hoist from the lifting chain.
material rope hoist’s lifting chain uses ultra-high molecular weight polyethylene fiber:
1. High intensity,strenght is ten times ofthe same cross section of rope with high breaking strenght -8mm diameter has 1.2T,diameter 11mm 2.9T.
2. Light weight,density is 30% lower than the average of nylon rope,which is very lightweight.
3. Super abrasion resistance,abrasion resistance ranks first among the plastic,and even better than some of the metal,which makes rope life greatly increased.
4. Impact,has a strong ability to absorb energy,which has outstanding impact resistance and cut resistance.Not to make ropeeasy to break,or to cut by sharp objects,ensure high security.
5. Anti-Aging,anti-ultraviolet radiation,anti-neutrons and y-rays,it is particularly suitable for outdoor use.
6. Other features,also has excellent electrical insulation properties,chemical resistance,low water absorption.
Customers interested in Bi-direction rope hoist can read the above advantages to determine whether they need a material rope hoist or a steel rope hoist.
