Product Description:

The masts adopt the standard bases from the MC range, allowing it to be adjusted to the desired height.
The adjustable bases are of the same type as those of the MC crane range, providing a choice of method of installation:
• on fixing angles,
• on cross-shaped base,
• on travelling gear,
• or as a climbing crane.
For easier management of your crane fleet, the standard elements taken from the MC range are assembled using pinned fish joints for ease and speed of connection.
|MCT 88|

MCT cranes are available with a wide range of optional features:
• Vision cab with or without air-conditioning
• Dialog VISU indicators
• Dialog Wind anemometer
• Top Tracing interference control and zone limitation system
• Remote control unit with indicator
• Automatic cartridge lubrication
• Auxiliary winch

• 5 models.
• Jib lengths from 40 m to 52 m.
• Maximum load from 2.5 to 5 tons.
• Maximum hoisting speeds from 2.8 to 82 m/min.

Fitted with jib lengths ranging from 55 to 65 m, the MDT Topless cranes boast hoisting capacities of 6 to 10 t.
Providing a suitable size for all your needs.
They allow complex multi-crane installations by considerablyreducing the height gaps and interference of cranes on work sites.
The assembly, erection, transport and even maintenance times are reduced, and as a result this helps to keep operating costs low.
Optimum productivity and greater safety make MDT Topless cranes the best alternative for all users or hirers.

Elegance and distinction
Their new shape is easy to distinguish from a distance.
The counter-jib projects a dynamic and refined design and the profiled jib, with a regular inclination, shows a fluid and
elegant line.

Minimized, compact and light package
Transport and erection
The shapes, dimensions and weights of the components were devised right from the design stage to scale-down the
package and save time. Only a single, small, mobile crane is required to hoist the packages and assemble them.

Assembly of the
counter-jib on the
The compact counter-jib has a reduced footprint, ballast supports and
stabilizer plates designed to be folded
away for transport.
The nose and stabilizer plates can be
simply unfolded which releases the
Assembly of the jib on the ground
Operation of crane fleets can be optimized thanks to the possibility of exchanging certain components of the crane jib with other models from the same range

Counter-jib ballast blocks with inclined bases are used for simpler dismantling on the ground, since they can be laid down easily.
No locking mechanisms are necessary, and the counter-jib can be unfolded easily.

Pinning is quick and simple thanks to the centering pins of the splice.

Q:What are the parts of a tower crane? What are their main functions?
The structural elements include the followingMain arm: carrying weight, and making the trolley have walking track.Balance arm: put up lifting mechanism, electric box, counterweight, and make tower crane to achieve balance torque, reduce the standard section of the bending moment.Tower cap: connect the main arm with the balance arm by the tie bar, so as to reduce the bending moment of the standard section.
Q:How to improve the stability of tower crane
Increase the overall weight of the base and weight, the tower structure to be strengthened.Crane wire rope is phosphate coated steel wire, galvanized steel wire, stainless steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment optimization of hot galvanized wire rope double - phosphating coating.
Q:How did the tower crane rise on the construction site? Fifteen
In the table below the tower crane is the upper part of the tower body has four jacks, the top of the cage tower (tower of each section is called a tower cage) a little bigger than the following (which can be installed under a small tower, heightening cage) need to jack up above "high rise to work, just a small tower added into the big cage, the cage towers bolted, or tall tower cage can be fixed.
Q:Is it difficult to test tower cranes?
See the ability of individuals, the first ticket 650 yuan graduation card ID card (copy) medical certificate according to 3 inch 3 days learning theory exam two days of practice examination through 15 days notice thank you hope to adopt licensing
Q:Tower crane installation, wind speed is greater than 12m/s, wind should stop operation,
Surface wind speed is greater than 6
Q:How many tons of tower crane QTZ80A lifting?
Lifting torque = mass * radius of gyration (amplitude). That is to say, the bigger the weight is small.
Q:How to distinguish self lifting tower crane with counterweight and lifting tower crane without counterweight
2 the tower crane without counterweight is mainly the city fast loading tower crane. It is characterized by the absence of balance arm, and it is impossible to have counterweightThe layman can not tell the can see the appearance, there are long steel structure before and after the weight of the tower body, and no weight of the tower body with only one steel structure (i.e. jib crane, structure)
Q:What are the necessary safety devices on a tower crane?
(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.
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 is the wall radius of a qtz50 tower crane?
The working radius is usually 50 meters. There are also 48, 49 meters. For example, 4810, 4910, and 5010, belong to 50 tons of tower cranes.Qtz50 resolves to:Q: crane;T: Tower type;Z: Jack up;50: lifting torque of 50 tons meters.
