QTZ63(TC5510 TC5013)tower crane is the new type designed by the latest standard .This machine is the self elevating tower crane of upper slewing,with functions of fixing adherence and climb .Reliadle capacities .beautiful sculpt and convcnient setting,.Starting and stopping are steady.The technical parameters are superior.
This machine adopts multlstage 3-speed electric machine for pulling; which realizes light load with high speed,heavy load with low speed,good empty-hook speed and slow emplacing,There are ilmit machine of mootional mechanism with accurate orientation.moment limiter with high precision,weight limiter and particular trolley of broken-proof beaning This can make machine operate safely.
Height of independent operation is30M,height of adherece operation is100M,max levei working space of jib is 38-42M,large covering surface and high efficiency.

| custom_attr2︰ | Properties and merits of QTZ31.5(3808/4206) tower crane
1. The load moment of QTZ31.5 tower crane is 315 K N.m, the maximum lifting weight is 3T,and the maximum working range is 38/42 meters.
2. The lifting height of QTZ31.5 tower crane can be 30 meters when standing stationary alone, and 80meters when anchored ,suitable for the construction of buildings lower than 30 stories.The structure of this tower crane is rational,for the main functioning steel parts,such as the tower and the crane,are made up of seamless steel tubes with proper hardness,little wind resistance and a pleasant appearance.
3. Combning the merits of the tower cranes of the same kind and improving their disadvantages,QTZ31.5 tower crane has better qualities and a more rational structure, and can be operated with safty.
4. QTZ31.5 tower crane has helmet structures with two hoisting points, adopts small trolleys, hoists with upper slewing liquid pressure, and it can be installed quickly and conveniently.
