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: would someone who study both white crane kung-fu & ninjutsu be called a mixed martial artist?: Most say they are mixed martial artists when they do MMA, but you are doing 2 different styles with standing techniques and ground techniques, so why not

Q: Like those huge cranes on the top of buildings that are being constructed - how do they get them up there???: depends on the situation some times they use another crane. some times it is hydralic lifts. they just keep adding sections to the superstructure from the bottom. as they go up they enclose the crane superstructure in side the envelope of the building and add sections of super structure as needed to change the height. then they bolt it back to the building

Q: Since a crane has to extend outriggers while performing lifting operation , is it ok to allow a crane to transfer materials by carrying without extending outriggers and lifting and carrying load to different location especially in construction industry for safety reasons?: It would work but there's the danger of the load swinging damaging the crane or other vehicles or losing it's centre of gravity toppling etc. when it's moving. For most lifts the outriggers are required to stabilise the crane itself - not the load. You're dead right - the on-site safety protocols that are in place these days demand that everything is done absolutely the right way. If anything goes wrong there's be hell to pay for anyone involved even if they've done their best to get things right.

Q: With hi-rise buildings being constructed left and right, i was just wondering, how do they raise cranes? this has really been bugging me for a time now..: JIP cranes are used to do so

Q: so yeah i know that cranes do the main work but i guess there are no such really toll cranes to do that with skyscrapers ?: That is a good answer. Ordinary cranes build the steel frame to a height of perhaps 60 feet. The frame is designed so a specially designed crane can climb up the side (like climbing a ladder) to about 50 feet where the climbing crane can complete the frame to about 100 feet, then the crane can climb to the 90 foot level and build the frame to about 150 feet etc. Another method is the floor at about the 60 foot level is completed and extra strong. A crane is assembled on that floor and can complete the steel frame to about 100 feet where another extra strong floor is built. The crane at 60 feet is then dismantled and moved to the floor at the 100 foot level, or perhaps this is a second crane. Repeat until the full height of the building is frame work. As cranes are removed at the lower levels, more floors can be installed and some of the finishing work done. Either way, you can see why very tall buildings are very expensive. Likely both methods are used for some very large and very tall buildings. Neil

Q: Tower crane body standard section connection bolt screw upward or downward, why?.: A few days ago, a special training course of mechanical equipment, a safety supervision station old experts say the screw from the upward wear, stress is the same, but if the nut screw will fall off, in order to find problems. If you can't get it off the top and bottom nut, you won't find it

Q: Why are there extra placards attached to the tower crane tower?: 2. after adding the placard, it will increase the windward area of the tower crane and increase the wind load of the tower crane, so that it will deviate from the calculation load when the tower crane is designed, and will affect the safe use of tower crane.

Q: in design of steel structures as per asce2005 or ibc2006 ,what load combinations are to be considered when crane loads and seismic loads are present?: Asd Load Combinations

Q: But theres always someone who gets a prize everytime. Its so unfair!lol: I suck at them lol. I actually like Spongebob (yea thats right), and im not afraid to admit it. Down here in the deep blue sea! It aint 80s I know but its pretty good nonetheless... and no im horrible at those skill cranes so I feel for Squidward in the episode...

Q: A crew built this huge crane to build an office building next to my house.... There is a huge flag hanging from the top of it.... Why does the construction company do this???: Wind becomes an issue when lifting large loads with a crane that has a long boom. On some large cranes you may see an anemometer near the end of the crane's boom. The crane operator will usually not make certain heavy lifts if the wind speed is too high. If the crane does not have an anemometer, they may be using a flag to tell them the direction of the wind and to give them a rough estimate of wind's speed.
