QTZ50(5008) 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:electromagnetic crane
- Current sent through a coil of wire creates a magnetic field, which can be used to pick up ferromagnetic objects. Turn off the current, and the field will turn off (although it might take a few seconds to turn off all the way), dropping the object.
- Q:Tower crane demolition safety technical disclosure, how to write?
- Baidu search:Tower crane removing and lowering joint safety technical disclosure.
- Q:why does the power company use helicopters to service the repair lines instead of trucks with tall cranes?
- High-tension lines operate at hundreds of thousands, or millions, of volts. At this potential, electricity can jump through several feet of air to reach a path to ground. This pretty much rules out using trucks, because it would be prohibitively expensive or impossible to build a crane out of entirely non-conductive materials. A helicopter is electrically isolated from the ground, so it's less difficult to drop a technician off and let him hang from the line itself while working. (It is still necessary for the technician to use a wand to bring the helicopter to the line's potential before starting work, because of the capacitance of the helicopter's body.) They could of course use a truck to service the lines if the power was disconnected, but the cost of shutting down service to an entire region of the country exceeds the operating cost of a helicopter.
- 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:Where you stand on one leg with your hands up and out to sides.Isn't standing on one leg in a fight leaving you exposed and vulnerable? What techniques can you actually do from that stance anyway (other than jumping up and kicking with the leg that was on the ground like the karate kid).
- Kung Fu Crane Stance
- Q:Secured to a concrete floor with 12 30mm bolts
- That can only be answered by analizing it. A crane as you are supposed to know has different loads and directions of impact due to the moving bridge, the trolley, and break loads. So what it can lift depend on the whole structure. Besides depends as much on the type of crane
- Q:I know that the whooping crane population recovered through captive breeding but how many are left currently (right now).
- There were 535 total in 2009--the population increased slightly last year but I have not seen a total for the population of 2010. Deaths can occur at any time so the number changes constantly. The Journey North site counts 281 adults in the wild western population and 106 birds in the reintroduced eastern flock. They did not give a number for the birds in captivity so I cannot give you a total. You can follow the reintroduced whooping crane population and their migration each spring and fall on the Journey North (in fall called Journey South site). They also track song birds and hummingbirds and monach butterflies.
- Q:How do cranes get from one construction site to another without hitting streetlights, wires, car, buildings?
- they fold up
- Q:All types of jack up cranes. How is the maximum lifting torque converted?
- Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
- Q:I know you need to put current around the magnet (or certain type of metal) in order to attract but is it possible to use as pushing an object away. if there is please tell me how!
- To push an object away, you need equipment that is low to the ground when it applies the force. Bulldozers are designed to push objects. Electromagentic cranes are designed to deal with vertical forces, so they are used to lift and drop metal objects. They use electricity to flow through coils wrapped around a metal core to generate a strong magnetic field. Trying to use them to push things could cause a crane to tip over since they are not designed to deal with horizontal forces. Even if you could get the electromagnet wired to repel metal objects, when you bring the electromagnet near the object, it would repel away in an unwieldy manner because of friction and interference with the ground. And trying to direct a large electromagnet at the end of a long chain would be difficult.
