QTZ125Z 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: like a really really clear set of instructions. or a video. but evrything i have tried confused me.: there's a website called origami club that has pretty easy tutorials also tons on youtube.

Q: Notice of tower crane: Please refer to the technical regulations for the safety of installation, disassembly and use of tower cranes in construction;The following is copy:3 installation of tower cranes3.1 conditions for installation of tower cranes3.1.1 tower crane installation unit must have the construction administrative departments issued the contracted professional qualification and heavy equipment installation engineering construction enterprises safety production license. Tower crane installation units must be engaged in the installation of tower cranes within the scope of qualification permit.In addition to the professional and technical personnel who have the qualification standard, the installation units of 3.1.2 tower cranes shall also have professional personnel who are in line with the project. The person in charge of the project, the project manager and the full-time safety management personnel shall have the certificate of safety production inspection. Tower cranes, installers, electricians, drivers, signal engineers, cable operators should have special construction operation qualification certificates.3.1.3 construction units shall sign professional contract for installation engineering with the installation units, and make clear the responsibility of both sides for safety in production. In case of general contracting of construction, it shall be signed by the general contractor and the installation unit.

Q: What should be included in the disassembly plan of the tower crane?: - 2 - (1)Project and safety supervisor with safety certificate and mechanical management personnel.(2)Construction crane with qualification certificate for construction operationMachinery installation, disassembly, lifting, signal workers, electricians, lifting drivers, cable operators and other special operations personnel.The above constructors shall fill in the name, type of work and qualification number of the constructors.11 、 installation procedure and safety quality requirement;In strict accordance with the tower crane product specifications, installation procedures and safety quality requirements of the implementation of the organization of safety construction technical disclosure and signature confirmation.12, installation self-test;After installation, the installation of the unit with the installation quality testing, debugging safety device and complete self-test report.13, major sources of risk and safety technical measures14, emergency plans and so on

Q: Is there a crane lifting chart where I can enter info. to determine what size crane I need, if so where?: Sorry, it's not quite that simple.

Q: crane wreak during stadium construction: Big Blue: January 20, 2000: Video of the Big Blue crane accident that happened in the Brewer's Ball Park Stadium on July 14, 1999 in Milwaukee, Wisconsin. Three men lost their lives in the accident. Although the video is only 1 minute and 10 seconds in length, seeing it is an experience you won't soon forget.

Q: What should I do with them? who would accept them if I donated them?: Maybe go to a children's hospital and see if they will accept it. If they won't maybe they will know of an organization that will.

Q: hi, i was just looking for a guide to change a full stock to a crane stock on an m4, (its wired to the back)i dont actually have the gun yet im buying it from a freind, so i havnt had a chance to look at it but the the gg gr16-r4i was wondering if its just a m4 with a stock that is wired to the back, how there is the two long screws that run from the back of the buffer tube to the body, then you just switch it out for a crane stock...anyway anything would be great, thanks: you need a crane stock and a buffer tube for it. the full stock does not use a buffer tube. you simply guide the wires through the buffer tube (once you attach it to the back) and into the stock. then just pu the stock on and put the batteries in and viola! crane stock!

Q: I was wondering if Steam Cranes are still used to clear train derailments or are the all mothballed now? What do they use to clear derailments now days if the not the Steam Cranes? Also way are there 2 types of hooks on the crane anyway? Thanks: I am not aware of any steam cranes, they are all diesel as far as I know. the two types of hooks are for different types of pulling, one is generally for straigh lifting and the other for pulling across the ground or up an embankment where the pulling force is at somewhat of an angle to the equipment. .

Q: this wind speed refers to that height of wind speed?: Surface wind speed is greater than 6

Q: Just curious... I'm not in construction and always wondered...: The top sections of the mast beneath the crane are removed one at a time and lowered to the ground. The top section of the crane has hydraulic rams that lower it down one mast section at a time. It is hard to describe without a diagram or photos. See photos at attached link. In some design, the jacking portion is at ground level. The crane jacks itself up so a 20' section of the mast can be unbolted and slide out. Then the jack is lowered so the process can be repeated. See second link for photos and a more detailed explanation.
