Product Description:

Introduction:

Tower crane is used to lift, lower and horizontally move materials in construction and other industry. It has large lifting capacity and lifting height, wide moving range, and can rotate. It basically consists of base foundation, mast, slewing unit, working jib, counter jib, counterweight, hook, and operating cabin.


Features:

1. A universal model, suitable for various construction projects and working conditions.

2. Adopt standard section hydraulic lifting and connecting, can adjust crane height according to height of the building

without affecting the lifting capacity.

3. Use three-speed motor and mono-speed ratio decelerator, trolleying mechanism can provide two operation speeds: low speed for heavy and high speed for light load. Steady operation, stable braking and less shock when shifting.

4. With complete set of safety devices, with lifting height limiter, dolly range-change limiter, moment limiter, weight

limiter, circumgyrating limiter and so on.

5. Scientific layout, beautiful appearance design. The operator's room is set independently on one side, with good vision field.

Q:How do they use cranes at +600 meters hight to build a building like the Burj Khalifa?
The cranes are jack-up cranes. They have their own self-contained jacks. As one floor is completed, they jack up to the next level. The cranes are on top of the buildings. They are designed by structural and mechanical engineers to loift a given weight.
Q:How were Railroad Steam Engines from 1830 to 1890's recovered before the advent of the Wrecker Steam Crane.?
Old Man Dirt is right. Block and tackle. Remember too those early engines weren't that heavy. The most common type from 1850 to the 1890s was the 4-4-0. They, and the other types were usually between 25 and 60 tons. I don't necessarily collect old rail photos, but I've seen many hundreds in other people's collections. And early locomotive salvage was usually block and tackle, with another engine brought in to furnish the muscle required. Since this could be a lengthy process if the wreck was extensive, a temporary track, or sometimes called a shoo-fly would be built to move trains past the derailment, or to enable getting another engine and hoisting equipment positioned.
Q:What is the rental price of a tower crane? General site rental more, but also buy more? Ask the industry for an answer?
315, 40 months rent about more than 10000, some have the strength to buy ah, rent two years is enough to buy one. Ha-ha
Q:Tower Crane Testing?
Q:what are the number meanings for paper cranes?
Hey Mary, Don't let the web site name fool you, it does discuss the deeper meaning behind paper cranes. Steeped in ancient myths and carrying resonant cultural meanings, the crane occupies a central role in the Asian imagination. Anyone who has witnessed cranes flying through the early morning mist over shimmering green rice paddies will readily understand how the mysterious beauty of the crane has captivated Asian life and art for centuries. Like the dragon, tiger, and phoenix, the crane ranks among the favorite motifs for Asian artwork because of its rich meaning and history. Read more at the web sites.
Q:John Steinbeck and Stephen Crane?
Try Maggie: A girl of the streets, which is the novel I think of for Crane being part of the Realist school. I think you can also see Steinbeck, in his selection of subjects as being in that same school of fiction. So less for their style and more for their choice of subjects.
Q:how do calculate Gear box toque & speed in EOT crane?
Your okorder.com/... contact them with your enquiry. You must include Model and anticipated loads as that determines torque applied. Seed is operator dependent for safe operation.
Q:How do they get big cranes on top of high rise buildings?
The tower crane is build on sections of steel structures from ground level, they build much higher than needed, so the protuding section at the top that houses the crane do not need to be removed all the times, that probably explains the cost of building. They probably start to remove the protuding section when it reaches a height which is easy for machinery to access.
Q:Does anyone know where I can order Sugar Crane to grow?
Crane? anyway,, if your store has those little pieces you can buy to eat? or if you know someone with canes,, you strip off the hard outer covering,, this has the seed buds,, plant these in 3 inches of soil and wait,, cane is slow growing!! if you google sugar cane growing or go to wikipedia you will find plenty of info google buy sugar cane seeds you will find sites to order!!
Q:What windproof devices should be set up for crane work?
Safety protection device and function of crane1. overload limiterIt is a safety guard for cranes to prevent overload, also called a weight limiter. The safety function of the utility model is that when the crane load exceeds the rated value, the lifting action is stopped, so as to avoid overloading. Overload limiters are widely used in bridge type cranes and elevators. Some boom type cranes (such as tower cranes and gantry cranes) use the overload limiter and the torque limiter together. Overload limiter has mechanical, electronic and many types.(1): mechanical drive ram through a lever and a spring cam, etc., when overloaded, hit the switch control rod and the lifting action phase, cut off the power source of hoisting mechanism, control the lifting mechanism to suspend operations.(2) electronic: composed of a sensor, an operational amplifier, to control the actuator and load indicator, display, control and alarm and other security functions in a body. When the crane is loaded, the sensor on the load bearing component is deformed, and the load weight is converted into an electric signal, and the value of the load is indicated by operation amplification. When the load exceeds the rated load, the power source of the lifting mechanism is cut off so that the lifting action of the lifting mechanism can not be realized.
