Product Description:

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

Q:container crane truss design?
Jimmy: The American Society of Mechanical Engineers (ASME) produces design standards for many types of cranes: see the link below. Many crane owners, licensing and governmental authorities having jurisdiction over cranes require design, fabrication and testing to ASME standards.
Q:Ways to help Japan with origami cranes?

Q:How does a climbing or tower crane work?
They add extra stages from the bottom. A tower crane is erected from a boom assembly, first and second tower sections of different cross section, and a base in a sequence of steps in which the boom assembly is mounted on a hollow climbing section dimensioned to be received in each of the larger second tower sections and defining a cavity dimensioned to receive each of the first tower sections. One of the latter is secured on a base in upright position, and the upright section is received in the cavity of the climbing section which is then raised relative to the first section and enveloped by one of the second sections. The enveloping section is secured to the base and the raised climbing section for supporting the climbing section whereupon the first tower section may be released from the base, raised, and secured to the second tower section. The climbing section may then be raised relative to the first tower section to permit the installation of another second section, and the procedure repeated, until all second or larger tower sections are superimposed on each other, the one first section being ultimately attached to the topmost second section. When the climbing section is raised relative to the attached first section, another first section may be superimposed on the one first section and the procedure repeated until the slimmer portion of the tower is assembled from superimposed first sections. Ultimately, the boom assembly is attached to the topmost first tower section, and the climbing section may be removed or stored for further use on the wider, lower tower portion.
