1 It adopts standard sections (for models of over 12t) of piece assembly structure, split structure stock, and assembled platform, which meet the transport requirements for standard container.
2. The extra-long boom is designed with a rope-supporting trolley, and the speed of which is 1/2 of that of the luffing trolley, which can achieve the most optimum rope-supporting effect. The structure has applied for national patent.
3. The lifting mechanism adopts speed regulation by frequency control or by eddy current brake series resistance, featuring good lifting performance; The slewing system adopts frequency control by torque electric motor or by coil winding type electric motor with hydraulic coupler, featuring smooth operation and small slewing impact.
4. All kinds of safety devices are reliable and easy to adjust; both the safety monitoring control system and traditional safety system are available, the double system ensures safety operation of the tower crane; the hydraulic system adopts low/medium pressure design, featuring higher safety and reliability.

 

The Vietnamese Son Da Corporation company ordered 4 MD 900 B cranes for dam construction.
The 250 LCC hoisting mechanism enables a productivity of approx. 70-80 m³/h depending on the site conditions.
Trolleying and slewing mechanisms with frequency variations.

The Longtan Hydropower Development Co Ltd purchased 3 Potain giant tower cranes, with latest technology,
for the construction of the Longtan Dam in Guangxi Province.
The project was to build concrete gravity dam, with roller compacted concrete for the spillway and conventional
concrete for the power house and the ship lock.
3 620 000 m³ roller compacted concrete were poured, including 590 000 m³ for the coffer dam. The final dam
height is 190 m and the crest length is 750 m. Completion 2010.

Q:What are the requirements for jack up and plus section of jack up tower crane?
When lifting, a standard section is hoisted on the imported beam or introduced platform. Then open the pins or bolts connecting the standard section with the slewing support. Start the oil pump, so that the cage in the standard section of the outward sliding, until the release of a standard section position, and then imported beam or imported platform on the standard section into the connection. This completes a process.

Q:How to calculate life span of steel structure? for example, crane?
With bridges that you would be able to calculate an anticipated lifespan. It is going to now not be very particular. You measure the deflection as a given load goes over it. You also measure deflection with average site visitors.You are taking measurements of what normal visitors is. With this knowledge that you would be able to undertaking lifespan and prefer exchanging bridges earlier than they crumple. Once I was once a engineering student I had a summer time job serving to to experiment bridges.Most bridges and gigantic constructions are designed to are living 50 years I believe. For constructions I have no idea of any measurements you would take. I think it is most often a matter of periodic inspections. The things to seem for are basis problems, cracking of concrete, exposed re-bar, concrete flaking off etc.
Q:when do i start bernie cranes missions gta 4?
you don't unlock the Bernie Crane Missions until you complete Weekend at Florian's for Ray Boccino. The first Bernie Crane mission is called Hating the Haters where you have to run with Bernie in the park and kill the guy that's been harassing him.
Q:how much would a crane for furniture cost?
Talk to a lumber yard that has a boom truck. Ask them how much to do it. A boom truck will cost much less than a crane. A boom truck can reach 45 to 50 feet. In this economy they are looking for anything they can get. They will most likely do it. But when really busy they wont. But things are slow. Builder 30 years. A crane will cost about 250.00 of the first hour. with a one hour min.
Q:Which is the main basis for the disassembly and assembly process planning of tower cranes?
Before the installation and disassembly of 2.0.10 tower cranes, special construction plans shall be worked out to guide operators to perform installation and disassembly operations. The special construction plan shall be prepared according to the actual conditions of the product specifications and the working site of the tower crane, and shall comply with the requirements of the relevant laws, regulations and standards. The special construction plan shall be examined and approved by the technical, safety and equipment departments of the unit, and approved by the technical person in charge, and shall be approved by the supervision unit.2
Q:What do lattice boom and hydraulic boom in cranes mean?
LATTICE BOOM: See first link. This is where the boom (the portion used to support the load) is made like a lattice ... i.e. interconnected trusses and girders. The cables for lifting the load are run from the base of the boom to the load over pulleys/gears located at the boom's tip. The boom itself is NOT adjustable in length or in angle. HYDRAULIC BOOM: See second link. This crane uses hydraulics to adjust either the length of the boom, or the angle at which the boom joints intersect. It looks more like a single beam construction, although its probably closer to a tube type design (hydraulics may be inside or outside the arm). The load is raised/lowered by cables operating at the end of the boom ... not necessarily tied back to the bottom of the boom.
Q:Does tower crane belong to special equipment?
Tower crane is a high-altitude operation, the type of work belongs to special types of work, equipment belongs to special equipment.
Q:what attracts Crane flys?
