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

5. This Tower Crane equipped with hydraulic lifting and connecting. The height can accordign to the actual height of the building and at the same time unchange the lifting capacity.

6. Frequency control, variable speed, smoothness and high stability, non-striking.

7. Three-speed change pole motor, simple in structure, economical ,fitting.

Q:Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
the requirement for selecting the steel quality group based on the results of brittle fracture evaluation of steel is increased;Environmental requirements and nondestructive testing requirements for welds are increased;- increased the number of institutional requirements;- increased the type and requirements of some of the units;- - increased technical data requirements that manufacturers should provide;- added some information labeling requirements;- mounting and climbing requirements are increased;The inspection requirements of tower crane are described in detail.
Q:Tower crane and construction hoist service life? What are the norms and standards? How to detect?
According to Hangzhou quality safety supervision station (2011) No. 56 document:Six, strengthen the use of longer construction crane management1, more than the required number of tower cranes and construction hoist should be qualified units for security assessment, the specific years with reference to the following requirements.Tower crane: 630KN.m (excluding 630KN.m), factory more than 10 years of age (including 10 years); 630KN.m1250KN.m (excluding 1250KN.m), factory more than 15 years of age (including 15 years);
Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
1. Tower crane consists of three parts: metal structure, working mechanism and electrical system. The three main technical parameters are lifting moment, lifting weight and working speed. Lifting moment refers to the boom as the basic arm length maximum amplitude corresponding to the rated lifting weight of product, product or maximum weight with the corresponding inflection point.
Q:Four for crane, two for insurance, two for insurance. What does that mean?
Four limit: torque, ultra high, variable amplitude, walking limit device. Two insurance: hook insurance and reel safety device.
Q:What is the difference between crawler crane and tower crane?
There are many differencesThe crawler is used to transport items in a smaller range of motion (site)A tower, used for construction, stationary, or maneuvering along a railroad track.Crawler can easily reach the magnitude of 50 tons or moreMore than ten tons of tower are relatively commonTrack internal combustion engine, hydraulicTower type general power consumptionWait, wait......
Q:What is an attached tower crane?
Its weight is 5 ~ 100kN, lifting radius of 3 ~ 35m (trolley), the lifting height is 160m, the maximum lifting torque of 1600kN - m, each with high 2.5m, the QT4 - 10 type crane lifting system comprises a lifting sleeve frame, long stroke hydraulic jack, bearing seat, lifting beam and a positioning pin. The cylinder block of the hydraulic jack is installed on the support seat at the bottom of the tower, and the lifting process can be divided into five steps.
Q:Examples of filling and acceptance forms for tower cranes and examples of filling in.
4 data filled in the requirements of the project, in addition to fill in the above sign, but also need to fill in the corresponding data. Data that needs to be filled in should be separated by "/" or "," and, if necessary, distinguished by text or graphic.
Q:Tower crane (tower crane)
In the form of the structure for the tower type, flat type and movable arm type. The model can be divided into QTZ63 suspension, QTZ80 crane, QTZ125 crane, QTZ crane, 315 crane and so on according to the moment division. Now used to arm length + tip weight of the way named, for example, 5513, that is, the longest length of 55 meters arm, the tip of the largest weight of 1.3 tons.
Q:Protective earthing resistance of tower crane
Q:Calculate the tower crane gantry crane
Is building gantry crane crane, gantry crane is generally used for the port, port crane. Can not be regarded as the tower crane.There are several common types of cranes: overhead cranes, gantry cranes, port cranes, automobile cranes, tower cranes, etc..Gantry crane is a medium and small cantilever crane with simple Longmen.
