The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for315Kn.m;the maximum hoisting load of 3t and the maximum working radius of 39m.The hoisting height of anchoring tower crane is 25m and that of climbing tower crane is 100m.
The tower crane has ingenious design, beautiful shape and simple structure .It is easy to operate and maintain, and is safe and at a reasonable price .It is an ideal construction machines for construction enterprises. It has hoisting mechanism, swing mechanism, top-rising mechanism and radius mechanism, which can work individually or cooperatively to make a high efficiency. The top-rising mechanism is used to raise or lower tower. The hoisting mechanism has 3-speed electronic motor respectively for high, medium and slow hoisting speeds. It has flexible swing mechanism and radius mechanism and slewing mechanism for vertical and /or horizontal transportation of building materials in one time.
The tower crane has complete and sensitive protection devices such as hoisting weight limiter, hoisting moment limiter, hoisting height limiter, radius limiter and swing limiter to ensure of regular operation. It also has rest platform, guardrail and other protection devices. Driver’s cab is at a side of rib and has big space and wide visual field.
The tower crane has excellent performance and is suitable for hoisting in short civil or industrial buildings or loading or unloading in ports or goods yards

- Q: Safety rules for tower cranes
- Three. Check after shutdown3.1 after the tower crane has stopped operation, it is necessary to select the suitable position of the barrier and the middle of the track when the turret is turned and the arm to stop along the wind, and then lock all the rail clamps.All 3.2 tower crane rotary mechanism with a normally closed or braking device, in the stop after the operation, the driver must remove the handle, release the brake for crane in the wind blowing in under the direction of rotation.3.3, the hook should be lifted to the minimum distance from the lifting wall, not more than 5m position, hanging on the hook is strictly prohibited. Not to take reliable measures, not by any means, limiting the boom rotate with the wind.
- Q: I still cannot grasp how a crane was taken apart on a building with no roof
- They used a climbing crane , and who said that the building has no roof? the crane parts can be dismantled on site and removed either by helicopters or using the construction lifts
- Q: hiya :) for my birthday i want an arcade style grabber machine that can pick up sweets and accept real money etc. I dont want small plastic ones because they are pretty pathetic tbh. I know its a bit random but i really appriciate it because my birthday is coming up ;) i want it being in the range of ?60-?100 :) thanks
- Sweet Grabber Machine
- Q: I have learned how to make crane but I just can't! I've watched about 6-7 videos for it and i still don't get it!
- If that doesn't help at all , try pictures with words . Here are my two favourite sites . They have good instructions and pictures . Really simple to understand .
- Q: Hi,I am looking for study for Design, Calculation and selection of Overhead Crane supporting Columns. (Not the Crane runner way beams ) Could you please suggest me the suitable references on internet?Thank You !
- See okorder /
- Q: What are the conditions of tower cranes, strictly prohibited?
- According to the national standard "tower crane safety regulations" (GB5144-2006) requirements, "the installation and disassembly, section, or drop section operation, wind tower crane at the maximum installation height should be no more than 13m/s, when there are special requirements, according to user and manufacturer's protocol implementation." Wind speed 13m/s, that is, 6 winds.
- Q: I know it sounds like a silly question but I just wanted to know what kind of crane he is because I've never seen a crane with black feathers.
- Red-crowned Crane is a large crane and is the second rarest crane in the world. In East Asia, it is known as a symbol of luck and fidelity
- Q: what do you think happened to ichabod crane?
- I heard he went our for smokes and never came back.
- Q: Which is the main basis for the disassembly and assembly process planning of tower cranes?
- .0.11 tower cranes should be prepared before the installation of special construction program, and should include the following contents:1 project overview;2 installation location, plane and elevation;3 types of tower cranes and technical parameters of performance;4 basic and attachment device settings;5, climbing conditions and adhesion nodes detail;6 installation sequence and safety quality requirements;7 weight and suspension position of main mounting parts;8 installation of auxiliary equipment type, performance and layout;9 power settings;10 construction personnel allocation;11 rigging and special tools;
- Q: This poor little guy has been out on my balcony where I smoke my cigarettes for two days now. One wing is badly mangled and he can't fly away, I thought to just let him work it out yesterday in hopes of him healing on his own somewhere, but today he was climbing on my leg as if asking for help and I feel horrible for him now...he's suffering, he hasn't gone far in at least 24 hours I feel I should feed him and give him water until he heals...what do crane flies even eat?? Any advise aside of killing him and putting him out of his misery would be great!!
- Well, it looks like they only have a lifespan of a 2 weeks at the most, so I'd just make him comfortable and let nature do its thing. According to Wikipedia, adult crane flies don't really eat--they just hang out and mate... If you really want, I suppose you could put some sugar water in a bottle cap or something for him.
