Please follow the !ethods and re"uire!ents of the Manual to handle the tower crane. #$1% tower crane is a new type tower crane &ointly designed 'y our co!pany and Changsha (uilding Machine )cade!e according to the latest version of *G+T#%,-/, Tower Crane Classification. The crane is a !ultipurpose tower crane with hori0ontal &i' trolley radiuschanging function top swing function and auto!atic rising function. The crane has the following features 1. 2ts functional para!eters and technical indexes are leading in China and up to international advanced level. 2ts !axi!u! working radius is #$!. 3. The crane has the 'eautiful outline and is very popular to custo!ers. ,. The crane has two working !odels the anchoring !odel and the cli!'ing !odel. The hoisting height of the anchoring crane crane is 4%! and that of the cli!'ing one is up to 14%! through adding standard sections and supporting devices. 4. 2t has high working speed good speed ad&ust!ent function and sta'le working state. 2ts swing !echanis! adopts planet reducer and its toprising !echanis! has co!pac co!pactt struc structur ture e and and high high effic efficien iency cy.. They They are easy easy to !aint !aintena enanc nce e and safe safe to operate. #. 2t has relia'le safety devices which are !echanical and electrical devices and are adapta'le to 'ad outdoor environ!ent. 5．2t has dou'le'ar hanging &i' with good rigidity and s!all weight. 2t has 'eautiful figure and s!all wind resistance. -．The ca' is installed separately with 'ig space and visual field. $ ．2t has no center collector ring so as to prevent fro! rain short circuit and other failure. 2t is easy for operate to go through. 6or the a'ove features it is suita'le for high civil 'uildings 'ridges workshops and high wall 'uildings such as chi!neys.
