Product Description:

QTZ40(5008) tower crane is hoisting and conveying machinery which is designed by Shandong Fuyou Co., Ltd. by fully utilizing the group technology, the combinational design technology and the finite element analysis technology and taking the tower crane microcomputer design platform as a tool and has excellent performance.

The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the effective amplitude of 50m and the maximum lifting moment of 438kN•m. The tower crane has the lifting height of 29m and the adhesion lifting height of 120m (2 magnification) during independent use.

All the speed indexes of the crane meet or surpass national standards.
The crane has the total installed capacity of 24.9kW, features advanced parameters, excellent and reliable properties, attractive appearance, high quality, simple and practical structures, advanced safety devices, convenient maintenance, safe usage and reasonable prices, and is ideal construction machinery for many medium-small construction enterprises

The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

Q:What is the insulation resistance of tower crane?
Three. Technical specification for temporary power safety on construction site JGJ 46-20055.4.2 within the construction site crane, derrick and Longmen machinery equipment, metal structure and steel scaffolding and under construction in construction projects, when lightning protection devices in adjacent buildings, structures and other facilities outside the protect zone of lightning arrester, lightning protection device should be installed in accordance with the provisions of.5.4.7 lightning protection electrical equipment machinery, connected to the PE line must repeat grounding at the same time, with a repeat of the mechanical and electrical equipment grounding and lightning protection grounding machines can share the same grounding body, but should be consistent with the repeated grounding resistance of grounding resistance requirements.The electrical equipment of 9.2.1 tower crane shall comply with the requirements of the current national standard "safety regulations for tower cranes" GB5144.9.2.2 tower cranes shall be subjected to repeated earthing and lightning protection grounding as specified in Clause 5.4.7 of this code. The earthing device of the track type tower crane shall comply with the following requirements:L the two ends of the rail are respectively provided with a grounding device;The joint of the 2 track is electrically connected, and the ends of the two tracks are electrically connected in the loop;3 long track every is not more than 30m and a grounding device.
Q:What are the working mechanisms and safety devices of tower cranes?
About the structure: Tower cranes are all metal structures, so far there is no wood. About institutions: tower crane working mechanisms are: winding lifting mechanism; luffing mechanism; slewing mechanism; cart moving mechanism; lifting mechanism.
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:What are the four major moving mechanisms of a tower crane?
Four big bodies of tower crane: lifting, slewing, luffing and walking.
Q:How to fix the cable on the tower of QTZ125 type tower crane?
segments can be fixed after solving this problem, usually with plastic copper (with insulating layer) and insulator is fixed on the tower body section,
Q:What is the calibration value of a tower crane?
Do you mean the calibration value of crane lifting moment? That should be the product of the maximum magnitude of the tower crane and the corresponding maximum lifting load.
Q:How to install the jack up tower crane 30How to install the jack up tower crane?
Since it is self lifting, as the name suggests, it is on its own power that no other crane can rise. It has a special elevated section, a hydraulic device, the upper section rises, the middle empty time section, with his arm to be added to the festival hanging near the artificial it fixed, so that a section of the rising of the. Is to support themselves, and then in the middle plus standard section.
Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?
In short, when the tower rotates in the form of a tower, the tower is stationary (ie does not follow the rotation), and the form of the lower turn is the tower will rotate. As for the reasons, the main consideration is the actual needs.
Q:Tower crane (tower crane)
In the form of the structure for the tower type, flat type and movable arm type. The model can be divided into QTZ63 suspension, QTZ80 crane, QTZ125 crane, QTZ crane, 315 crane and so on according to the moment division. Now used to arm length + tip weight of the way named, for example, 5513, that is, the longest length of 55 meters arm, the tip of the largest weight of 1.3 tons.
Q:What type of tower crane does not include tower crane in variable amplitude mode?
Mobile tower crane: a tower crane with running device and can walk.
