The QZ type grab bridge crane is a double-girder bridge lifting equipment specially designed for bulk material loading and unloading conditions. A dedicated crane for heavy-duty duty class. The whole machine adopts a double-box main beam structure and is equipped with a special four-rope electric grab as a material grabbing device. It can independently complete the entire process of material grabbing, lifting, transfer and unloading without the need for auxiliary spreaders. The equipment has stable operation, high operating efficiency, and high automation capability. It is specially designed for high-frequency loading and unloading scenarios of various granular, powdery, and lumpy bulk materials such as coal, sand, gravel, ore powder, slag, and grain. It is widely used in stockyards, power plants, ports, steel plants, mines, and other working conditions.A primary (leading) lifting device for bulk material storage and transfer.

Core advantages

The QZ grab bridge crane is specially designed for bulk material operations, with significant advantages in automation and operating efficiency: the whole machine adopts a high-strength double-beam welded structure, which is sufficiently rigid, impact-resistant, and fatigue-resistant. It is suitable for high-frequency continuous grabbing operations. It is not easy to deform during long-term heavy-load operation, has a low failure rate, and has extremely high durability and structural strength. Is standardly fitted with a special four-rope grab, which opens and closes synchronously, has a large grabbing capacity, little material residue, even grabbing, and thorough unloading without manual assistance, which greatly saves labor costs and improves loading and unloading efficiency; the power of the entire machine's operating mechanism is reasonably matched,crane travel and trolley traverse operate smoothly, and the alignment is accurate, which can covers a full range of material grabbing and transfer operations with no dead corners and transfer without dead corners, comprehensive operation coverage; sealing optimization for dusty working conditions, high dust protection level of electrical components, able to adapt to harsh working environments with dust for a long time; complete safety protection configuration, standard overload limiter, travel limiter, buffer and anti-collision, emergency shutdown,the trolley (small car) and the crane travel (big car) move smoothly and other devices, the grab bucket operates stably without risk of bucket decoupling or slipping; it supports cabin control and wireless remote control in multiple modes, and can be upgraded with variable frequency speed regulation, intelligent automatic material grabbing, material measurement, and remote monitoring systems to adapt to the needs of automated material yard operations, and also supports customization of various non-standard working conditions.
