Description of our Tower Crane

The tower crane is a combination of advanced technologies of the present day. The electric control system of the tower crane adopts the advanced “PLC + frequency converter” control mode of the present day, which has realized the stepless speed regulation and greatly improves the reliability, maneuverability and stability of the control system and the work efficiency of the tower crane.

TC 5511 tower crane belong to upper-swing hydraulic climbing tower crane with horizontal jib, winch-jib. All kinds of performance parameters and technical items are up to or better than the National Standard. The max radius is 50m. Independent loading-lifting height is 30m. Attaching loading-lifting height is 121m. The rated load moment is 630KN.m .

Advantage of our tower crane
1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.
2, suitable for the group of tower cross homework.
3, boom stability is good, combination amplitude range.
4, suitable for height have special requirements occasions construction.
5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

Q:How much is a team of 40 tower crane
Tower crane rental generally do not rent pricing, can not count number, not today is installed, removed tomorrow!Usually on a monthly basis, with or without use!
Q:What special operators should be equipped for the installation and disassembly of tower cranes?
According to the requirements of the 2.0.3 specification: tower crane tower crane installation and disassembly operation should be equipped with the following: 1, hold a qualified safety assessment certificate of the project and responsible for the safety of people and machinery management personnel; 2, with construction qualification certificates for special operations of the construction hoisting machinery installation and disassembly, lifting work, special operation signal heavy drivers, riggers and other operations personnel. And an electrician.
Q:Method for operating tower crane
In the 2.11 operation, when lifting the weight, the weight should be higher than the height of the obstacle, at least 100mm.2.12 when the crane is approaching the track limit, it should slow down and stop in advance.2.13 when lifting heavy objects, not heavy lifting suspension instability, no additional weight in lifting objects, lifting scattered materials or special-shaped components must be used when the wire rope firmly tied to heavy lifting from the ground about 50cm stop, determine the brake materials, lashing and rigging, confirmation before lifting command.2.14 cranes must be adequately illuminated at night.2.15 crane in the stop, rest or midway power failure, the weight should be unloaded, not to weight suspended in the air.2.16 the operating room, no personnel shall enter, prohibited flammable and impede the operation of the items.2.17 is strictly prohibited or promotion personnel riding crane. Landing weight, weight is prohibited to stand.2.18 the boom and lifting pieces of cranes must be in safe distance from overhead transmission lines, and shall comply with the provisions of this schedule 30.1.6.2.19, two cranes in a track or two parallel or vertical orbit on the operation, should maintain the safety of any part of the distance between two machines, the minimum shall not be less than 5m.2.20 in case of any of the following circumstances, suspension operation shall be suspended:1., in the event of bad weather, such as heavy rain, heavy snow, fog and construction work surface has six (including six) above the strong winds, affecting safety construction.2. crane leakage occurs.3. serious wear of wire rope, to scrap standard (wire rope scrap standard see Appendix A).4. safety guards fail or display inaccurate.
Q:What are the "2 magnification" and "4 magnification" mentioned in the lifting characteristics table of tower cranes?
Popular saying: "car to hook this section of vertical distance, you see 4 wire rope is 4 magnification, you see 2 wire rope is 2 magnification.".
Q:How to choose tower crane in engineering, such as arm length and lifting weight?
First of all, your engineering structure is reinforced concrete Or steel? What's the weight of the lift? The lifting capacity of tower cranes should meet the needs. Generally speaking, steel structure hoisting, tower crane of the largest lifting weight and gravity moment should be large; hanging steel reinforcement of a smaller can.Secondly, the boom length should be covering the scope of construction (can also be arranged to meet several sets of crane lifting coverage). But in the 360 level luffing jib range, can not have obstacles (other cranes and buildings), and the boom and the distance between them (below) should be not less than 2m.Third, in the construction project is relatively high, the site is relatively small, you can mount the internal climbing tower crane. Building covers a large area, sometimes one can solve the problem. Of course, it is more troublesome to disassemble and lift inside, but the standard section used is less and the cost can be lower.
Q:What are the qualifications for site installation and acceptance of tower cranes and construction lifts?
This really did not hear, the site installed to be tested, usually installed, in accordance with the safety procedures, acceptance of the OK
Q:In the case of tower crane operation, the operation should be stopped
In case of six or more gales, heavy rain, heavy fog, heavy snow or tower crane, you should stop working
Q:What is the safe distance of a tower crane to the surrounding buildings?
JGJ160-2008 "construction site mechanical equipment inspection technical regulations" on the 46 page clearly written, safety distance shall not be less than 0.6 meters,
Q:What is the difference between a tower crane and a jack up tower crane?
The fixed tower crane means lifting the foundation of the tower body on the foundation or structure through the connecting piece.
Q:What are the types of tower cranes?
The tower crane is divided into: fixed tower crane mobile tower crane self lifting tower crane mobile tower crane is divided into: rail type tire type automobile type self lifting tower crane is divided into: attachment type climbing uses: concrete with cage for loading and unloading installation general building mixed
