A single beam bridge crane is a lifting equipment that is horizontally suspended above workshops, warehouses, and material yards for material lifting. Due to its two ends resting on tall cement columns or metal supports, it has a bridge like shape. The bridge of a single beam overhead crane runs longitudinally along the tracks laid on both sides of the elevated structure, making full use of the space below the bridge to lift materials without being obstructed by ground equipment. It is a type of lifting machinery with a wide range of applications and a large quantity.　　Application scope　　Single beam bridge crane is an important tool and equipment for achieving mechanization and automation of the production process in modern industrial production and lifting transportation. Therefore, single beam bridge cranes are widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industries, railway transportation, port terminals, logistics turnover and other departments and places.　　Precautions　　(1) Each crane must be clearly labeled with its rated lifting capacity.　　(2) During work, no one is allowed to be on the bridge or transported with hooks.　　(3) No one is allowed to drive a crane without an operating license or under the influence of alcohol.　　(4) During the operation, it is necessary to concentrate and avoid talking, smoking, or doing unrelated things.　　(5) The car should be cleaned thoroughly; Do not place equipment, tools, flammable materials, explosive materials, and dangerous goods indiscriminately.　　(6) Overloading of cranes is not allowed.　　(7) The following situations are not allowed to be lifted: mechanical parts are overloaded; Signal unclear; Diagonal pull; Objects buried or frozen in the ground; There is someone on the suspended object; Flammable, explosive, and hazardous materials without safety protection measures; Overloaded liquid items; The steel wire rope does not meet the requirements for safe use; The lifting mechanism is malfunctioning.　　(8) When the crane operates on a line without obstacles, the hook or lifting device and the bottom of the lifted object must be at least 2 meters above the ground. If crossing an obstacle, it must be 0.5m higher than the obstacle.　　(9) For lifting objects weighing less than 50% of the rated lifting capacity, two mechanisms are allowed to operate simultaneously; If the lifting capacity of an object exceeds 50% of the rated lifting capacity, only one mechanism can operate.　　(10) Bridge cranes with main and auxiliary hooks should not raise or lower the main and auxiliary hooks simultaneously (with special exceptions).　　(11) Do not weld or hammer on the lifted object, and do not work underneath the object (if supported).　　(12) Inspection or maintenance work can only be carried out after a power outage and when a power outage operation sign is hung on the switch. If live working is necessary, safety measures must be taken for protection and a dedicated person must be assigned to take care of it.　　(13) Do not litter from the car.　　(14) Limit switches and interlock protection devices should be checked regularly.　　(15) It is not allowed to use limit switches as a parking method.　　(16) When there is a problem with the lifting brake, it is not allowed to lift heavy objects.　　(17) The suspended object is not allowed to run over people or equipment.　　(18) When welding a certain part of the crane, a dedicated grounding wire should be set up and the machine body should not be used as a grounding wire.　　(19) When the hook is in the lower limit position, there must be at least two safety rope loops left on the drum.　　(20) Cranes are not allowed to collide with each other, let alone use one crane to push another crane for work.　　(21) When lifting heavy objects, liquid metals, explosive and dangerous goods, it is necessary to slowly lift them 100-200mm off the ground to test the reliability of the brake.　　(22) The voltage of the lighting fixtures used for repair and inspection must be below 36V.　　(23) All electrical equipment enclosures of bridge cranes should be grounded. If the car track is not welded to the main beam, welding ground wire measures should be taken. The grounding wire can be made of galvanized flat iron with a cross-sectional area greater than 75mm2, bare copper wire with a cross-sectional area of 10mm2, or galvanized round steel with a cross-sectional area greater than 30mm2. The grounding position of the driver's cab or crane body should be more than two. The grounding resistance between any point on the crane and the neutral point of the power supply should be less than 4 Ω.　　(24) Regular safety technical inspections should be conducted, and pre inspection and pre repair work should be done well.
