Main Features

 

1)  tower crane is one of the key product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.

 

2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected; The max. attached height can reach 180m.

 

3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.

The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.

 

4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.

 

5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.

Q:how does the power electronic drives employed in cranes?
The primary function of an electronic drive is to provide for operation at various speeds. Slow speed operation is used when moving a load into position. Faster speeds are used for moving loads over longer distances. When the operating speed is steplessly adjustable, ramped acceleration and deceleration control is easily provided as well. Controlled acceleration provides smoother operation because acceleration at a constant rate means accelerating with a constant force or torque. Electronic drives control torque and current during starting. They perform a function similar to a reduced voltage motor starter, but they do it steplessly, more efficiently, with more complete control of applied torque. They provide more torque per ampere of current than any other starting method. This is very beneficial for the frequent starting and stopping often required for cranes. Electromechanical motor controls for cranes require additional contactors, relays and other components to perform functions such as reversing, motor overload protection and braking. These functions are incorporated into the electronic controls with electronic drives. Electronic braking can return energy to the power supply and bring the load to nearly a complete stop before a friction brake is applied. For holding the load in position, an electromechanical brake is still required. Electronic drives can be used on bridge, trolley and hoist applications.

Q:What is the function of the balance valve in the hydraulic jacking system of tower crane?
The function of the balance valve is to maintain the balance of the oil pressure, the hydraulic oil delivery flow is stable, so that the tower crane jacket and the upper part of the lift, disassembly, standard time, lift and smooth.
Q:method how to assemble tower crane?
Generally tower cranes are self erecting. The first mast and jib sections are assembled at ground level. The mast and jib are then jacked up and another mast section inserted. If the tower crane is not self erecting then mobile cranes have to be used to assemble the crane.

Q:How would you be able to tell the difference between a crane fly and a mosquito?
Really easy: A crane fly has no long piercing mouthpart: they feed mainly on nectar Female mosquitos have long piercing mouthparts, males are smaller and have shorter mouthparts for sucking nectar from flowers. Common crane flies are almost always bigger than a mosquitos.
Q:i have to make a children's story about how the whooping crane became endangered; (based on real facts) ideas?
You could write a story about an old Whooping Crane with lots of children that goes on migration only to come back and find her home has been destroyed. So she goes and starts trying to raise awareness about it, and eventually finds a new home due to her efforts. This would need much more tweaking and changing of course.
