Characteristics of QTZ125
Characteristics of QTZ125
1. QTZ125 TC6015 tower crane, a type of self-elevating top slewing tower crane, which has good quality and competitive price.
2. This tower cane is the crane with vertical arm support, trolley travel and up-rotary hydraulic jack-up system. Its maximum load capacity is 8t. maximum radius is 60m. Tip load is 1.5t, independent height is 45m, max. Possible height is 150m.
3. Our company use France Schneider contactor,and tests each hoisting mechanism under no-load, static load, dynamic load, etc. To ensure the brake reliable, safe and durable.
4. Cabin with humanized design,is convenient and comfortable,facilitate for safe driving.It creates a good working environment for the operator.
5. The machine is equipped with complete set of safety devices, which can guarantee the safe and high efficient operation of the equipment. Including lifting height limiter, dolly radius limiter, load moment limiter, weight limiter, circumgyrating limiter, etc.
6. Our tower crane expands the international market actively,and has successfully exported to Asia each country, middle east, Brazil, Russia and north America, which has become foreign trade long-term cooperation.
7. We comply with CE and ISO9001-2000 international quality management system standards.
8. Reliable quality, advanced technology and equipment, competitive price, the best configuration, high safety factor, cost-effective ---MINGWEI products is trust worthy, we can ensure the customers buy the products assured and use happy.
