Product introduction
Rail-type container gantry cranes is a special machine for loading and unloading in container yard of the container terminal and container transfer station. It's composed of double gantry frame and transverse connection beam, the gantry frame is supported on a walkway and on track, but the frame has two forms: cantilever beam and no cantilever beam.
Features
Modular design- According to the commonality, regularity of product parts, form hoisting mechanism module, luffing mechanism module, trolley traction module, trolley assembly module, crane traveling mechanism module, steel structural module, function module, general module, etc.
- Adopting removable links between to install and deliver conveniently.
- Producing standard module to ensure stable product quality and shorten delivery time.
- Steel plate shot blasting pretreatment, surface quality is up to Sa2.5 Level.
- Using the digital cutting machine to cut the web plate to ensure the smooth and precision of the camber curvilinear.
- Adopting automatic submerged arc welding for the main weld, ultrasonic, X-ray nondestructive flaw detection, 100% qualified.
- Adopting advanced coating equipment and technology to protect the crane from salt fog and marine climate corrosion in its use process.
- Security monitoring system equipped with overload limiter and real-time load value is displayed on the screen to prompt the operator to prevent overloading.
- The controller will perform a self-test before starting, including the power supply voltage level, default phase, button zero status and validity of each safety device.
- Crane driven wheels are equipped with wheel side brake, setting electric interlock between wheel side and crane traveling mechanism. Under the effect of the hurricane, the crane is not easy to slip with high safety coefficient.
- Motor, reducer are imported or domestic famous brand, industry recognition, and quality assurance, reliable quality.
- Electrical components and parts select Schneider, Siemens, ABB and other international brands, electric control box protection rating of not less than IP54.
- Raw material adopt Bao Steel, Wuhan Steel, Hansteel, strict quality control, make checks at all levels to ensure every product with high quality.
- Adopting advanced active rectifier technology, to give feedback to power grid about the energy causing by weight drop and excess energy causing by mechanism braking, enhance the power factor, reduce running cost and meet the demand of energy conservation and environmental protection.
- High-speed running trolley run along the front and back bridge girder orbit of shore bridge for sea and land side direction, the trolley traverse speed can up to 240 m/min, significantly improve the efficiency of container loading and unloading.
- Through the encoder position detection and spreader moving orbit dynamic memory storage technology, automatically calculate the best and safe path, on the premise of security, greatly improves the working efficiency.
- Crane safety monitoring system, record every operation of the crane.
- Can be equipped with the international leading crane electrical swing technology, achieve precise localization of crane.
- Malfunction automatic detection technology, with malfunction display and diagnosis function, help maintenance personnel clear trouble quickly.
- Through the real-time detection frame relative to the deviation of the orbit, automatically correct skew frame to avoid crane gnaw rail.
