Product Description:

QTZ50(5010A) tower crane is hoisting and conveying machinery which is designed 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 500kN•m. The tower crane has the lifting height of 30m 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 25.5kW, 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 are the safety devices for the horizontal arm self lifting tower cranes?
(1) the lift height limit position limiter must be able to stop lifting motion immediately when the lifting device is raised to the 8OOmm at the lower end of the boom. For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately. (2) lifting moment limiter and maximum weight limiter; when lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped. If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value. When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.
Q:What can paper crane symbolize?
the crane is for the life that goes on after you leave earth
Q:Im looking for more information on Overhead Cranes!?

Q:what is the best type of crane certificate to get?
Tower cranes and Gantry Cranes Since toer cranes are the most used in the construction industry gantry Cranes are used in all Ports for loading and unloading containers has a vast scope of work
Q:what is the function of load indicator on a crane?
Two things, The maximum lift and the maximum extension of the boom. The maximum lift is based on weight and structural considerations and the maximum extension of the boom prevents the crane from turning over. The weights on the back of the crane is prevent the crane from turning over. TexMav
Q:What a crane is .........?
It is Maximum weight, Minimum Radius, Minimum boom length
Q:The special equipment specified by the state is a periodical inspection cycle, wherein the crane is carried out every many years
(two) small light lifting equipment, bridge crane, gantry crane, gantry crane, cable crane, crane mast, railway crane, jib crane, mechanical parking equipment every 2 years 1 times, the crane annual molten metal and hot metal 1.The rated load test, static load test and dynamic load test shall be carried out in the first test and the first periodic inspection, and the rated load test shall be carried out 1 times after each of the 1 inspection periods.The inspection process, the existence of major risks of hoisting machinery (such as special work environment, frequent accidents, etc.), inspection agencies approved by the provincial quality technical supervision department agree, can be appropriate to shorten the regular inspection period, but the short period of not less than 6 months.
Q:Aggressive Sand Cranes?
Sounds like the aggressive is the Dominate male of the herd. I know you like to feed them but that's what started the problem. He is being Dom so he can get more food and be the first to eat. Once they figure out you're not going to feed them they will go back to behaving normal. These are cool to look at, even though they can get loud sometimes. Have you ever seen tourist feed sea-gulls at the beach. Locals don't do it. Sea Gulls will get as aggresive as the Sand Cranes and actually dive bomb people. Imagine what a Sand Crane can do being what 10 times the size
Q:Materials to build a simple crane?
Mcgrath is a very dedicated and experienced woodworker who knows what he is talking about when it comes to woodworking and DIY projects s he has been a woodworker for many many years.
Q:Stephen Crane and Willa Cather (talk about your odd couples) met briefly. He died shortly after at 29, I think
Due to my present situation, I have thought about this many hours. Many days. Many months. Time, or the lack of it, is generaly considered the enemy. But there are situations that the less of it can be a blessing. None of us can ever know which we will wish for. Until that time comes.
