QDXX European-style double-girder bridge crane is a new generation of lightweight, energy-saving, high-precision heavy-load bridge-type lifting equipment. It integrates European FEM standard design concepts and domestic mature manufacturing technology to complete all-round upgrades and optimizations on the basis of traditional QD double-girder cranes. The whole machine adopts a high-strength box-shaped double main beam modular structure, and is equipped with a European-style integrated lifting trolley and variable frequency drive system. It has the remarkable characteristics of light weight, small wheel pressure, compact overall dimensions, and high operating accuracy. The equipment is suitable for installation in modern standard factory buildings, effectively improves the utilization of factory space, reduces civil construction load-bearing costs, and can be stably and competent for medium-to-high-frequency, high-precision, medium-to-large tonnage continuous hoisting operations in the long term. It is a high-end upgraded replacement model for traditional heavy industry cranes and is widely used in various modern intelligent manufacturing workshops.

Core advantages

Compared with traditional ordinary double-girder cranes, the QDXX European-style double-girder crane has been fully upgraded in terms of comprehensive performance, energy saving and adaptability, and its core advantages are outstanding: the whole machine adopts an optimized design of lightweight and high-strength main beams, with strong structural rigidity, resistance to deformation and fatigue resistance, no shaking during heavy-load operation, and excellent stability. The overall dead weight is 20%-30% lower than that of traditional models. Its wheel pressure is reduced, and the load-bearing pressure on the beams and columns of the factory is lower, which greatly reduces the cost of new factory building and renovation; the extremely compact body layout, reduced hook approach distance, the effective lifting height is larger, the operating range under the same factory conditions is far beyond that of traditional cranes, and the space utilization rate is greatly improved; the whole set adopts European-style integrated drive and variable frequency speed regulation system, starting and stopping softly, without impact, and low It has accurate speed alignment and low operating noise, which can meet the needs of precision equipment hoisting and high-precision assembly. The core components are modular and standardized, convenient for disassembly and assembly, low failure rate, longer service life, and low life-cycle operation and maintenance costs. The energy-saving effect is significant, the energy consumption is much lower than that of traditional cranes of the same specification, and the economic advantages of long-term use are obvious; The safety protection system is complete, with standard equipment such as overload limiter, multiple stroke and travel limiters, buffering and anti-collision, emergency stop, pressure loss and phase loss protection, etc. Intelligent anti-sway, remote monitoring, and load monitoring systems can be installed as needed; it supports wireless remote control, handle ground operation, and cab control modes, and can be customized for special working conditions such as explosion-proof, anti-corrosion, dust-free, and high temperature resistance.
