Product Description

 Key Processing Step to ensure the quality

1, Advanced material -heat -treatment processing to ensure the quality.

2, Automatic union melt welding ensure its beautiful looking and strong welding joints.

3, Double sided milling machine ensure each mast section connected closely and firmly.

4,All steel experience  rust removal for twice.

 

 Features

1, Safe and efficient control system.

2, Lifting mechanism is controlled by variable frequency speed control system, multipolar winding motor , resistance speed regulator and  pole conversion speed regulator. .

3,Liftign mechanism speed regulator functions well, can be braked effectively and  shift gears smoothly.

4, Thick, short and welded big rolling device improves rope rolling effeciency and lengthen the steel rope lifespan.

5, CRV stepless speed regulator and PLC central controler are  conbined into one.

6, Computer programme control, the signal reflect back, the faults can be displayed and be automaticly protected.

7, Updated PLC can change the analog signal into digital signal, which shorten the faults removal time, improve its accuracy and anti-interrency capacity.

8,RCV turning control can be stepless speed regulated, which will results in precise brake and easy maintenance.

9, Soft lifting will produce no shock, which will improve the tower crane safety and its service life.

10, The most advanced and stable PLC controller is totally intelligently controlled, which will provide safe pretection against the operator's mis-operation. It has faults detecting and signal testing functions.

11, There are fewer intermediate control components, which result in easy maintenance and higher reliability and safety.

12, All electrical components are from world famous brands.

Q:why was the japanese crane hunted for its plumage in the 20th century?

Q:as a wife, what can i expect if my hubby joins the navy reserve as a crane operator?
he will only be paid for the days he is actually Mobilized. so if ends up with a traditional one weekend a month/2 weeks a year, then he gets paid only for that time. Boot camp and schools do count as mobilization, though. But typically, reserve Pay is much less than what he would be making in the civilian community, so chances are things will be very tight when he cannot work his normal job. As a crane operator, I assume he's is going into the SeaBees. Those guys are being deployed with great regularity to the sandbox for terms of 6-18 months at a time. different rules apply for deployments, including you being eligible for Medical and dental benefits while he's deployed. You and he both need to sit down and have a good long conversation with his recruiter to find out EXACTLY what will happen as far as his tarining goes and where he will be sent for his duty station.
Q:Any origami site with this one? Kissing Cranes?
Now, If the guy was 75 yrs old, with beautifull gray hair and can ballroom dance, and asked If he could kiss me , I would say yes, The one thing I hate is when a guy opens his mouth over yours and thinks thats a kiss, I would have to tell him I don't need a bath. Or that I don't need to be swallowed up. If he's that hundgry he should go get something to eat at A fast food place. HA HA HA.
Q:Can the tower crane personnel install the construction elevator?
Although it belongs to the construction of special operations, but the operation of different categories, tower crane demolition workers according to the requirements can not install the elevator!
Q:What is largest weight of the load that is safe for a crane to lift?

Q:What are the necessary safety devices on a tower crane?
(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.
Q:What is your favorite poem by Hart Crane?
How about my favorite poem about Hart Crane? AT HART CRANE’S TOMB by Glenn Robert Swetman In his mind’s dark, he spoke a frivolous age where marriage of the like was spring, where vitelline worlds of virgin instinct were crushed in the obscene cleanliness of a raccoon’s paw. Did he imagine that his great sun could come trailing yellow handkerchiefs of light, like a queer comet? No, there is something out there that commands, and not worlds of perfect clipping will turn these rotund hedges into maypoles—and live. That’s why the green expands as it reaches. He must have seen this finally. His leap Into the green sea was, aesthetically, clean.
Q:Calculate Work Done by a Crane?
The total work done by the crane equals the potential energy gained by the wrecking ball and the cable; the potential energy gained is W = V_final = Mg L + ρ L g L/2 which is the final potential energy of the wrecking ball and the cable added together. In the case of the cable, you take the center of mass of it which is located right at the center (L/2). The result is then W = 3000*32*40 + 10 * 40 * 32 * 40 / 2 = 4096000 ft-lbf = (4096000)*(0.001285067) BTU = 5263.63 BTU
Q:how does the power electronic drives employed in cranes?
Most large cranes run electrical motors. Depending on what power is available at the site, the crane may run from a generator or be powered by the grid. The power requirements depend on the size of the crane. Larger cranes may use a six-pole, three-phase, one-wye, 440-volt circut. Smaller cranes could use a three-phase 220-volt circuit.
Q:How do crane operators get up there?
They climb a ladder up the middle of the central tower. I saw 'it' on the History Channel. .
