1.Supper max. placing radius 42m, 2.Tower type, max. height 200m, 3.CIFA technology Boom, 5section, RZ pipe - details see: https://www.machineto.com/42m-zoomlion-tower-concrete-placing-boom-hg42t-5rz-10092963

1.HG42T Tower placing boom integrates lots of technique such as self climbing tubular column, self lifting for assembly, light weight booms. And It has lots of characteristic such as wider placing range, higher freestanding tubular column, it is first made in china, and has advanced technique. National patent has been applied for the kind of the tower placing boom.

2.Special adjusting and control equipment when climbing, the whole course of climbing is on the safe side, and own the absolute intellectual property rights for HG42T tower placing boom.

3.HG42T hydraulic system is a load sensing control system, and all the valve block groups are in high integration, so for system maintenance and hydraulic pipes' layout and connection. it adopts HAWE PSL series proportional direction valve made in Germany for the system, the dithering is weeny when booms are operating. The swivel reductor is always open, new kind of swivel braking system includes accumulator, check valve, electromagnetic directional valve, pressure switch and so on. It can automatically help the accumulator supply or release hydraulic energy, and supply braking energy for the swivel reductor. All are with the absolute intellectual property rights.

4.The light weight technique is adopted for boom design, the booms are lighter and it takes less energy unfolding and folding the booms. 5RZ boom structure form makes distance of the center of boom's gravity closer than before, the flexural moment becomes less, so the balance weight can be much less.

5.HG42T tower placing boom has a cab. there are three kinds of control modes as cab control, wireless remote control and wired remote control. PLC electrical control system is adopted, it can improve reliability and security, and presents humanization.

6. 2.0m×2.0m×2.8m integral type of standard section is adopted for the tubular column. it is with high intense, deformation of the tubular column can be reduced by 30%~40% than the same kind of products.And it is in all function with the standard tower section for tower crane.

7.Climbing mechanism adoptes a coarse reel of polygon rope groovy technique .More effectually, it settles down the problem that steel cable will enwind itself easily in the reel
