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. 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. This Tower Crane equipped with hydraulic lifting and connecting. This Tower Crane' s height can accordign to the actual height of the building and at the same time unchange the lifting capacity.
7. LVF: Frequency control, variable speed, smoothness and high stability, non-striking.
8. SM: Three-speed change pole motor, simple in structure, economical ,fitting.

Q:How many stops are there in a tower crane? Where are they located in the tower cranes?
The hook has an upper limit on the windlassThe car has front and rear spacing on the trolley hoistSlewing is limited to the slewing gearAnd the torque limit is on the spireWeight limit
Q:What is the insulation resistance of tower crane?
Three. Technical specification for temporary power safety on construction site JGJ 46-20055.4.2 within the construction site crane, derrick and Longmen machinery equipment, metal structure and steel scaffolding and under construction in construction projects, when lightning protection devices in adjacent buildings, structures and other facilities outside the protect zone of lightning arrester, lightning protection device should be installed in accordance with the provisions of.5.4.7 lightning protection electrical equipment machinery, connected to the PE line must repeat grounding at the same time, with a repeat of the mechanical and electrical equipment grounding and lightning protection grounding machines can share the same grounding body, but should be consistent with the repeated grounding resistance of grounding resistance requirements.The electrical equipment of 9.2.1 tower crane shall comply with the requirements of the current national standard "safety regulations for tower cranes" GB5144.9.2.2 tower cranes shall be subjected to repeated earthing and lightning protection grounding as specified in Clause 5.4.7 of this code. The earthing device of the track type tower crane shall comply with the following requirements:L the two ends of the rail are respectively provided with a grounding device;The joint of the 2 track is electrically connected, and the ends of the two tracks are electrically connected in the loop;3 long track every is not more than 30m and a grounding device.
Q:Why do tower cranes need to be fabricated?
Cement prefab, are generally large components, especially bridges more, including buildings, these components of large size weight, super wide is the transportation, these components must be used crane, crane can meet the needs of the heavy transport of goods.
Q:Tower crane demolition safety technical disclosure, how to write?
Baidu search:Tower crane removing and lowering joint safety technical disclosure.
Q:What are the working mechanisms and safety devices of tower cranes?
About the structure: Tower cranes are all metal structures, so far there is no wood. About institutions: tower crane working mechanisms are: winding lifting mechanism; luffing mechanism; slewing mechanism; cart moving mechanism; lifting mechanism.
Q:How many motors does the ZOOMLION TC6013A-6 tower crane use?
Model: YZRDW225M-4/8 power: 24/24KW speed: 1420/725r/minDirect search {ZOOMLION QTZ80 (tc6013) _ crane Manual Part 1 (Part Two)}, can also be found.
Q:What courses should I take to buy the tower crane to be installed?
First in the construction, some costs incurred during the installation, after installation costs together included in the original value of fixed assets.
Q:Operation points of tower crane (tower crane)?
Slewing bearing: tower crane is one of the most critical components, mainly to bear overturning moment and vertical load. After the failure, the demolition and replacement is extremely difficult, loss of large, so you have to check carefully to do maintenance, each 200H must be a senior grease lubrication from the rotary bearing surface, until now exudation. Slewing bearing adopts high strength bolt connection, if the pretension is not enough, or long-term operation, do not check, not fastening, will cause loose. If the individual bolts loose, will cause the remaining bolts overload, the consequences will be disastrous. The luffing mechanism only moves horizontally, the load is light and the line speed is not high, so it should be easy to master and operate. However, the amplitude involves the change of the lifting torque, and if there is no stopping in time, there will be the possibility of over torque. Therefore, the main requirement of variable amplitude operation is stationary parking and accurate positioning. The tower crane is of great height and the hanger is hung longer, so it is easy to swing the hanger when it is running. This is an objective phenomenon. What is called stabilization hook operation is how to make the swinging hook stop quickly, or how to make the hook move with the movement of the crane as soon as possible, and minimize the operation of the swing. The operation of stabilization hook is the skill that the driver should master.
Q:What does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
Q:What is the rental price of a tower crane? General site rental more, but also buy more? Ask the industry for an answer?
Is the site of the tower crane is not, the crane company specializes in the construction site is rented, the price range depends on the length of your period, due to demolition of the problem, I am not a professional, but I am working at the site, only know so much
