Double door frame is divided into rigid gantry legs hyperstatic

Railway yard gantry cranes ( hereinafter referred to as gantry cranes ) are mostly working in the open air , affected by natural wind . When the wind is greater than the steel crane predetermined value, the machine should be stopped . Or working in the state to stop the crane when subjected to strong winds , probably due to the wind and cause the brake device is not fortified gantry crane was blown away or tipping accidents , and even cause the plane crash . According to " crane safety supervision and inspection procedures " provides crane running on the track in the open-air work ( including rail gantry cranes ) , should be fortified wind devices. Two-stage wind brake effectively solve the wind braking railway gantry crane working state of hoist gantry crane emergency shelter under braking and static state . In the design and manufacture of gantry cranes , the correct choice of two levels of wind braking device is important . Hangzhou Railway Bureau tube gantry crane windproof two types of brake hydraulic brake wheel electric brakes two wind power hydraulic brake wheel brake device is a dual- power hydraulic brake system . In 36/16t gantry crane manufacturing , carts Traveling with double output shaft of the motor (YZR180L-8, 11kW), both sides were assembled brake wheel (φ300 and φ200), wind brake and brake work by the two were often closed electro-hydraulic brake blocks to complete.
