Product Description

QTD250-16t High Quality Tower Cranes Luffing Tower Crane


The function of the tower crane tip is to bear the upper load from the boom pulling rope and the balancing arm pulling rope, and to transfer directly to the tower body structure through the rotary tower, turntable, bearing and other structural components. The top of the self elevating tower has a truncated cone column, a forward or backward inclined truncated cone column, a herringbone frame and a diagonal bracing frame. The balancing weight is required for all the upper rotary tower cranes, whose function is to support the balancing weight to form the balancing moment opposite to the direction of the lifting moment required in the design. In addition to the counterweight, the lifting mechanism is often installed at its rear end. The reason why the lifting mechanism is placed at the end of the balancing arm together with the balancing weight is that it can play a part of the counterweight role, and increase the distance between the rope drum and the spire guide wheel, so as to facilitate the winding of the wire rope and avoid the occurrence of rope

1. Performance parameters of QTD250-16:

• Max. lifting capacity 16t;

• Max. hoisting capacity at jib tip: 9.57t;

• Max. lifting moment 2500 t.m;

• Max. free-standing height: 49.1m; Max. working height of anchored crane: 180.35m;

• Hoisting mechanism power: 60 kW; rope capacity: 600m;

• Slewing mechanism power: 2×145N.m;

• Trolleying mechanism power: 37 kW

2. Electrical control system

With PLC control, the electrical control system enjoys better reliability and safety. Produced by professional manufacturers with advanced foreign technology, the electrical elements feature service lives that are 3 or 4 times longer than that of domestic products, less faults, easy maintenance and repair as well as reliable operation.

3. Technical features

• The crane boasts of multiple operation modes and wide application;

• The complete machine adopts internationally well-received beautiful shape;

• The crane features high working speed and excellent speed regulation performance. Stepless speed regulation by frequency control, the world's most advanced solution, is adopted for the trolleying mechanism and slewing mechanism, thus ensuring more stable and reliable operation ;

• The cab is independently installed externally with good vision and large inner space, thus offering a good working environment for operators;

• A variety of safety devices are equipped, which are all mechanical or mechatronic products that are applicable to severe working conditions, so as to ensure the tower crane's reliable operation.

SHANGHANGDA machinery manufacturing Co., LTD is one of the first Chinese companies to initiate its own research capabilities in biomass pellet technology. Due to a lack of experience in biomass pelletization, most Chinese companies are completely dependant on outdated technology derived from machinery designed to produce grain feed. Disadvantages of these machines include high speeds of rotation, low output, low pellet density, high mechanical losses, and high manufacturing costs. Some of these problems persist within the industry in China to the present day.

After eight years of repeated testing and discussions, the group successfully adjusted the machine's main structure, greatly improved the ring die and compression roller, and made considerable gains in the machine's lubrication and transmission systems, thereby greatly enhancing its durability and efficiency in the pelletization processes. With these improvements as a basis, the group then developed a complete biomass pellet plant which is able to process sawdust, wood chips, straw and other biomass materials into pellet fuel. Pellets produced by the company's newly engineered plant are denser, more uniform in length, more lustrous and have fewer flaws. Its technical specifications comply with international standard

All of these factors have given SHANGHANGDA Biofuel Tech an advantage in China's biomass pellet processing industry, particularly in terms of mechanical research, manufacturing, the crafting of accessories, and in conveying. he group now has large mold forging workshops, China's most advanced ring die vacuum quenching furnace and a complete production chain consisting of several auxiliary equipment manufacturers. Coinciding with these developments, SHANGHANGDA Biofuel Tech has assembled a first-rate team to help inexperienced clients in the field achieve independent production. The group also helps clients design their production lines specifically to their required output, raw material usage, and site conditions with our complete service package of project assessment, installation, training and maintenance.

In the face of the fierce competition, SHANGHANGDA Biofuel Tech is determined to build a biomass machinery manufacturing enterprise influential both domestically and internationally. The company will ensure its success through scientific and technical innovation, securing its place in the market via impeccable quality.
