QTK40 SELF ERECTION TOWER CRANE
1.1 Brief introduction
The QTK40 model self erection tower crane is developed by our company on basis of years of experiences in production and new technical innovation.This tower crane is whole consignment & fast set-up vertical and level transport machinery. Mainly apply to 7~10 storey civil buildings. This machine also could used in factory, goods yard, station, ports to move products, as well as to be a mobile hoisting machine.
1.2 Features
The famous feature of this kind tower crane could realize fast-installation and whole consignment transportation. After whole enfolding of tower crane, two workers could transport tower crane by one truck crane (8ton), and the installation could be finished within 40 minutes.
Other features:
(1) Inner tower expansion in suit place, it could auto-lock and release
(2) lifting beam could auto-unfold or fold when towers stretch and unfold
(3) (Tower stretch and unfold, beam unfold, counter weight load ,which all could do range form 0~360°
(4) Adopt drum, whole steel wire rope pulley system, to realize lifting& installation set-up work
(5) Have two kinds interchange device: track and fixed supporting lug, to adjust different uses
(6) The angle of altitude of lifting beam is 15, then could increase the height of lift, but its Max lift weight is 1100kg .
(7) Lifting mechanism, trolleying mechanism and traveling mechanism adopt frequency & gear changable to control speed.
(8) Slewing gear adopt electric resistance control mode, smooth starting, with good positioning performance
