Warning! Your outdoor gantry crane must have this!
Gantry crane is usually used for material handling outdoors, such as, in ports terminals, where the environment is severe, especially in the summer, the typhoon Storm weather may occur. On the other hand, the gantry crane has large crane structure with large windward area, which is prone to be blown away. How to ensure your gantry crane safety in such bad environment? There are tips to ensure your gantry crane safety in the windy area. To install windproof anchor device on your gantry crane is one of the effective measures.
Wind anchor device is a kind of important large gantry crane safety device, and its role is to fix your gantry crane firmly in the job site.
Gantry crane windproof anchor devices
Wind anchor device
The device is connecting with crane operation field ground, simple structure, safe and reliable But with ground connection parts, must be in building docks built at the same time Need 4 sets of device when using, respectively installed on the cart running mechanism of four legs at the same time using bolt device at regular intervals along the rail on the site should be installed next, so that the wind came in a timely manner to lock the crane.
Manual rubber wedge
Manual rubber wedge is a simple and effective tool of wind, then insert it between the wheel and track, after the crane by the wind moving, rubber wedge on the wheel rolling, rolling friction between the wheel and rail into rubber wedge with the sliding friction between the orbit, resistance increases, the stop gate crane mobile manually rubber wedge disadvantage is that the need to rely on artificial insert and pull out, use convenient, in addition it and run institutions without electric interlock, sometimes accidents caused by mistake.
Wedge type anti-creeper
Pressure wheel fixed on the crane, the bottom has sunken wedge type, has a certain gap between them. When moving crane under the action of wind, wedge, along the wedge pressure wheel will can’t climb, vertical stress of wedge pressure round the wedge friction with the rail surface, when the frictional resistance can balance wind, crane will stop moving. Wedge with motion mechanism through raise and lower limit switch interlocking, to guarantee the normal work of the anti-creeper and prevent the disoperation run institutions. Wedge anti-creeper simple structure, low cost, high reliability, especially when the rail is lower than the plane, clip rails doesn’t work, it can work normally But it with rubber wedge, when there is a typhoon, the crane could still with wedge sliding along the rail surface, so the other wind anchor device must be installed.
Large cranes with no wind to anchor device, both at home and abroad by strong wind blown away, slip touch attack to the track after the end of tilting accident a lot Therefore, open-air homework large hoisting machinery must be installed wind anchor device, in order to keep the crane fixed up and prevent the storms blow away.
