Product Description:

Introduction:

Tower Crane is a machinery used for vertical lifting and horizontal delivering of building materials and any other heavy items during construction process. It can lift and lay down, horizontally shift, and rotate, so it has large working range.

 

Features:

1. 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.

2. 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.

3. 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.

4. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.

5. Provide stepless speed regulation. Outstanding in working efficiency, operating stability and reliability,

6. The height can accordign to the actual height of the building and at the same time unchange the lifting capacity.

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 are the forces acting on a car being picked up by a crane?
Gravity acts downwards, force = mass x acceleration. Crane acts upwards at same force. As the crane starts to lift the car there is upwards acceleration that causes more force to be generated for a moment.
Q:What Tower Crane Schools is there in Las Vegas?
check with the International Union of Operating Engineers. I know that in the past, they provided the training, and past the general operators certification, there is a Crane certification, and possibly also a Tower Crane endorsement.
Q:HELP! What to do with a thousand paper cranes?
use all of them to create one big one (assuming they're all similar)
Q:What does "jack up" tower crane 1000KNm mean?
1000KNm means that the rated lifting moment of the tower crane is 1000KNm. That is to say, the 100tm tower crane.
Q:1000 paper cranes question?
Consider what you would like your 100 cranes to mean. Attach strings to your 100 cranes and then hang them in a tree etc so that the wind may carry your prayers where they need to go. Then start again to create the 1000 paper cranes you want for your wedding. PS: The making of the paper cranes involves an act of faith, not the right colour to match your wedding plans. In Japan, the crane represents peace and healing. When we consider the famous Japanese art-form of paper folding (origami) the crane comes to mind before all else. Sadako and the Thousand Paper Cranes (1977), a non-fiction children’s book written by American author Eleanor Coerr, tells the story of young Sadako Sasaki who lived in Hiroshima at the time of the atomic bombing. Sadako developed leukaemia as a consequence, and lived out the remainder of her short life in a nursing home desperately trying to create one thousand paper cranes. Supposedly, if someone could make a thousand paper cranes his/her wish would come true. Sadako wanted to live. Sadly, she only managed to fold 644 cranes. After her death, friends and family folded the remainder, and buried her with the one thousand paper birds. Today, a statue of Sadako holding an enormous golden origami crane stands in the Hiroshima Peace Park. People regularly leave paper cranes. The plaque on the statue reads “This is our cry. This is our prayer. Peace on Earth.”
Q:Why am scared of crane flies but not spiders?!?
This is a selective entomophobia. Basically, you don't fear many insects or spiders, but specific ones trigger your anxiety. Your problem is not the bugs or spiders,(they are harmless) but your fear. This is something 'you' nurture by dwelling on this fear when you see one of these particular critters. I'm glad to hear you no longer fear spiders. you will see the same when you overcome your selective fear. You may even come to realize that the spiders and insects you do fear,are totally harmless, and you may reach a point where you can just ignore these. True, the crane fly is totally harmless and do not bite, sting, or inflict any form of hazard to humans. They can be a nuisance buzzing around your face,as they can be persistent. Adolescent years seem to be when phobias are the most prevalent, but also the easiest time to overcome fears. If you can learn to control your fear, rather than let it control you, you will overcome this. you also need to refrain from dwelling on your fear,as this will only make it worse. Last year, one of my favorite pass times was sitting on the porch watching the sunset. a little orb weaver would come from behind the light and spin her fancy web. Often, I would catch a crane fly that was bothering me and toss it into her web.
Q:Wall mounted tower crane
The construction of tower crane installation, operation and dismantling safety technical regulations "(JGJ196-2010) design provisions in article 3.3 attachment device of tower crane: when the tower crane attachment for use, attachment device settings and free height should comply with the provisions of the instructions; when the attachment level distance, attachment spacing does not meet the the instructions to.
Q:A thousand cranes' gift? (Korean context)?
I think that gift would be perfect for a teacher! If I was a teacher and a student gave that to me i'd cry. Have you heard about that book of the 1000 paper cranes? (Can't remember the name) but it says if you make a 1000 paper cranes then you get a wish. Well anyways make sure you present the presents nicely. Like put the cranes in a pretty jar with a beautiful ribbon wrapped around it and get flowers that're her favorite colors.
Q:What is largest weight of the load that is safe for a crane to lift?
(Wc)/(2b) for my problem.
