(1) Gusts refer to strong winds and tornadoes with unpredictable wind speed of 1.5 m/s (level 7);
(2) Typhoon refers to tropical storm, strong tropical storm and tropical cyclone with central wind force 12 or above;
(3) Large-scale port machinery (hereinafter referred to as large-scale port machinery) refers to: portal cranes, shore container cranes, grain suction machines, track gantry cranes, ship loaders (ship unloaders), tire container gantry cranes, bucket wheel stacker reclaimers, outdoor fixed belt conveyors, tire cranes (25 tons and above) and oil delivery arms. Chapter II Supervision and Implementation of Windbreaks and Typhoon Prevents Article 4 The port administrative department where the port is located shall be responsible for guiding and supervising the defense of large port aircraft and resisting gusts and typhoons:
(a) according to the typhoon information, issued a typhoon prevention order, the deployment of large port aircraft typhoon prevention work;
(two) to supervise and inspect the implementation of wind and typhoon prevention measures for large port machinery. Before the typhoon comes, it is necessary to check the typhoon prevention work of port enterprises, and focus on regular inspections during the typhoon season;
(three) to guide the work of windproof and typhoon prevention, and to promote the port enterprises to improve the technology and level of windproof and typhoon prevention of large port machines. Article 5 Port enterprises shall be responsible for the formulation and implementation of specific measures to prevent and resist gusts and typhoons of large port aircraft:
(a) combined with the specific situation of the unit, equipped with large-scale port machinery windproof and typhoon prevention technical devices, formulate windproof and typhoon prevention measures and working procedures in line with the actual situation, and organize their implementation;
(two) to strengthen contact and coordination with meteorological departments and other relevant departments, timely grasp the meteorological information, pay attention to the typhoon dynamics, and implement the prevention work;
(three) to strengthen the training of port production personnel, improve safety quality and awareness. Article 6 After receiving typhoon forecast, port enterprises shall arrange typhoon prevention measures in advance; After receiving typhoon warning and emergency warning, it is necessary to check and implement typhoon prevention measures and establish a 24-hour duty system to ensure the safety of large port aircraft. Chapter III Requirements and Measures for Windproof and Typhoon Protection Article 7 The design of port terminals shall take into account the requirements for windproof and typhoon protection of large port machinery, and the safety of large port machinery shall be equipped with gust typhoon protection devices (hereinafter referred to as windproof and typhoon protection devices). Windproof devices can be divided into horizontal and upward force devices to prevent wind, anti-skid braking devices and windproof early warning (warning) devices.
The device for preventing the horizontal force and floating force of wind refers to the device installed on the wharf to prevent the machinery from moving horizontally and overturning, including anchor pits, windproof mooring (or tie rod) ground anchors, mooring piers, etc.
Anti-skid braking device refers to the anti-skid device set by the machine itself and the inertia brake equipped by the walking mechanism, in which the anti-skid device should be selected from anti-creeper, wheel clamp, rail jacking device, rail clamp and iron wedge.
Windbreak early warning (warning) device refers to the equipment and facilities that receive, measure and record gust and typhoon information, and issue warnings and alarms. It is basically configured as an anemometer with recording and alarm functions. Conditional ports can choose to configure meteorological radar. Article 8 The windproof and typhoon-proof work of large port machinery shall meet the following basic requirements:
(a) the windproof devices of large port machinery shall be inspected and maintained regularly to ensure that they are in good condition and have the ability to prevent wind and typhoon;
(2) The docks and places where large port cranes operate should be equipped with sufficient mooring devices according to the actual situation of local gusts or typhoons, and effective improvement measures should be taken for docks and large port cranes that do not have the ability to prevent wind and typhoon to ensure that they have the ability to prevent wind and typhoon;
(three) the normal use of large port machinery should be complete and effective, and have enough braking torque. Article 9 A large rail-type port crane shall meet the following basic requirements in addition to the requirements of Article 8 of these Provisions:
(1) Anti-skid and braking devices shall be provided, in which the anti-skid device shall ensure that the equipment will not slip under the sharp action of 15m/s to 35m/s;
(2) When selecting a windproof device with horizontal force and uplift pressure, it is necessary to ensure that the equipment will not overturn under the action of on-site wind force of 35 m/s to 55 m/s. If the historical record of the 50-year maximum wind speed in the user's area exceeds the above range, it shall be fortified according to the 50-year maximum wind speed;
(3) The walking track should be flat, and stops made of reinforced concrete or steel plates should be set at both ends of the track, which should be firmly connected with the wharf foundation;
(four) should be equipped with wind warning (alarm) device, and technical testing, in order to meet the requirements of design wind speed warning and forecasting. Tenth large port aircraft to prevent sudden gust measures:
(1) In normal operation, the traveling mechanism of large port machinery should have good braking function. Under any circumstances, it is not allowed to reduce the braking torque of the walking brake without authorization;
(2) When a large port crane encounters a gust of wind during normal operation and cannot travel to the anchoring position, windproof measures should be taken at the scene, and the track should be blocked by means including windproof devices and goods to ensure the safety of the equipment;
(3) In the season with frequent gusts, after the large-scale port machinery stops working and moves the airplane seats, the operators should check and confirm that the windproof devices used are in normal working condition before leaving, and cut off the power supply after taking the following measures:
(1) The portal crane lifts the hook to the height above the cab, the boom retracts to the balance point or the minimum amplitude, and the turntable turns to the position where the boom is not easy to collide;
(2) The quayside container crane should collect the front load to the minimum, and lift the spreader to the highest position or design position;
(3) For the gantry crane of tire container, lift the spreader to the highest position and plug the tire anti-skid block. Tire container crane with legs (bridge crane) should lock the rotating pin.
