Cage makees vertical or banking motion, to convey the machinery of personnel and material.It is mainly used in high-building construction and maintenance,
It is also used as long-term use of vertical transportation machinery such as warehouse, harbour, dock, high tower.At present, many constructions for building in China
The matched cable of institute of terraced manufacturing firm all uses general rubber sleeve flexible cable, the cable in that case service life it is very short and
Security performance cannot ensure；Build special construction ladder cable technical requirements and general rubber sleeve flexible cable in technique and material
There is difference fundamentally.Common general rubber sleeve flexible cable can occur after using January as construction ladder cable in construction ladder
Torsional deformation, bulge, broken skin, until fracture cored wire the problems such as, cause cable service life partially short, a general busy construction
Lift up and down hundreds of times daily, day by day, cable lower excessive fatigue in the presence of twisting resistance and gradually deform, therefore one
As General Purpose Rubber cable be difficult adapt to used for a long time on building hoist.Analyze, have for existing market service condition
Necessity develops warping strength high flexibility construction ladder private cable to replace traditional construction ladder cable, this special construction ladder electricity
Cable mainly meets the lifter apparatus of domestic skyscraper.With the continuous improvement of lift height, to wanting for supporting cable
Ask and be very different, because in lift running, very big stress can be gathered inside cable, when the height of lift is big
Can more be increased in the torsional stress in 220m, cable, traditional Plastic-sheathed Cable be used for such height after, because internal torsional stress can not and
When eliminate or alleviate and frequently break core or cracking, the normal operation of jacking equipment can not be met, the service life of cable is short.At present
Domestic construction is used for 220m and the construction ladder cable of level above all uses general structure, and such cable is lifting
On machine using the deformation that is easily distorted after two months, bulge, broken skin, until fracture cored wire the problems such as, cause cable service life
It is very short and potential safety hazard be present.Daily hundreds of times up and down of a general busy building hoist, day by day, twisting resistance
Act on lower cable lower excessive fatigue and gradually deform, so the common construction ladder cable of in general is difficult in 220m and level above
Construction ladder is upper to be used for a long time.It is and domestic also without this class formation special product for 220m and level above.
Utility model content
