    Oil and gas lubrication of electric crane machines
    Oil and gas lubrication of electric crane machines

    Oil and gas lubrication is a new type of gas-liquid two-fluid cooling lubrication technology, suitable for high temperature, heavy load, high speed, very low speed and cold water, dirt and corrosive gas intrusion into the lubrication point and other working conditions are harsh.Oil & gas lubrication and oil & mist lubrication are all gas two-phase fluid cooling lubrication technology, but in oil and gas lubrication, the oil is not atomized, the lubricating oil is extremely finely continuously injected to the lubrication point, and the oil consumption is greatly reduced than the oil mis ...

    Principle the gantry crane track
    Principle the gantry crane track

    The principle of the gantry crane track is as follows:1. Should meet the stability requirements of the crane frame run along the direction of the crane track;2. The cargo dimensions shall pass through the steel frame of the gantry crane;3. Note that the wheelbase is proportional to the gantry crane span, and the wheelbase =(1/4-1/6) is generally taken.Single girder gantry crane

    The function of crane machine maintenance
    The function of crane machine maintenance

    When the crane machine is in use, the moving parts will be worn, the connecting parts are loose, the oil is transformed, the metal structure is corroded, and then the performance and safety of the crane machine are reduced. To prevent and eliminate hidden dangers, ensure that the crane machine is in a good condition. Good maintenance can play the following roles:1. Ensure that the crane machines are normal and reliable, improve their utilization rate;2. Strengthen the connection of the structural parts of the crane machine to ensure that the operation and function of the electrical components ...

    Brake check for jib cantilever crane
    Brake check for jib cantilever crane

    1. Each year or after 500,000 brakes, the butterfly spring group should be inspected. If the braking force is insufficient, the disc spring in the hydraulic brake should be replaced in time.2. The jib cantilever crane should adopt dynamic braking, it cannot only rely on mechanical braking. Otherwise, the brake disc will be heated, once an emergency occurs, it will affect the braking torque and cause an accident. 3. When replacing the brake shoe, should pressure it tight. If the size is not met, it should be repaired in time.4. The insufficient roughness of the brake disc and the large yaw ...

    The manual lever hoist
    The manual lever hoist

    The manual lever hoist is manually pulled by the handle, it is compact structure, light weight, small size, convenient and labor-saving, safe and reliable, long service life, small hand pulling force and small abrasion of the wire rope.The manual lever hoist solves the problem of lifting and transporting goods without energy power, and can be used in shipbuilding, electric power, transportation, construction, mining and other industries. Now let's explain the reason why the handle need large force to pull.Reason one: Overloading has always been the culprit of damage to the hoist. If the we ...
