The ME300+300t-50m double-trolley gantry crane is a bridge beam handling crane made for China Sichuan Project. It is designed with wide span and high lifting height. The gantry can be assembled into 2 sets 300t gantry cranes if needed.
1. The whole machine adopts frequency conversion and PLC control technology, which has stable lifting operation, small impact and low noise;
2. The trolley adopts European-style with compact structure, overall processing of small frame, and high assembly precision;
3. The gantry structure finite element analysis makes the structure more optimized and more reasonable, and flexible to make 1 crane to 2 cranes (transform one ME300+300t-50m, lifting height 52.5m gantry crane into two MG300t-23.5m, lifting height 28m gantry cranes);
4. The running mechanism of the crane adopts 64-wheel structure, single-sided double-row rail, and adopts multi-stage balance beam and Haval hinge structure to ensure the balance of the walking wheel. Overall processing of the wheel group and the balance beam with high assembly precision;
5. The components are durable and maintenance-free, equipped with hardened surface reducer, welding reel, rolling pulley and forged wheel;
6. Fast on-site installation without welding works;
7. Adopt CTS electrical modular system, convenient maintenance;
8. The whole machine is equipped with safety monitoring system and crane electric correcting device, and reserves interfaces of electrical intelligent anti-sway, intelligent jog, automatic positioning, remote monitoring and other interfaces.
