140 Ton Metallurgical Overhead Cranes
Scope of application:
Metallurgical cranes are mainly used in metal smelting, bundling and hot processing. Including open hearth charging bridge crane, overhead crane, traveling crane, ground charging crane, material box crane, stripping crane, dies or tools lifting crane, uncovering crane, clamp crane, slab turnover crane, forging crane, heating furnace loading crane, material box-electromagnetic crane, material box-grab crane. Other similar metallurgical cranes can also be used with reference.
The design and manufacture of metallurgical cranes shall conform to the relevant provisions of GB3811
(1) Environmental condition
The power of the crane is usually three phase AC, with a frequency of 50Hz and a voltage of 380V or 415V. The upper and lower limits of allowable voltage fluctuations on motors and appliances are +10% of the rated voltage and - 15% of the rated voltage (at peak current). The internal voltage loss of the crane is less than 5% for the stripping crane, the clamping crane, the whole model crane with guide frame and the slab overturning crane. Other categories in this standard Type cranes should not exceed 4%. If the power supply has special requirements, it can be determined by the supplier and the buyer according to the needs of users.
(2).Crane working environment temperature and humidity
ii.Crane working environment temperature generally -10~+50℃.
ii.The relative humidity of B. is not more than 50% at +40℃.
(3)No inflammable, explosive or corrosive gases shall be allowed in the site where the crane is used and shall comply with the relevant standards and documents.
(4)The installation of crane trajectory should generally meet the requirements of GB10183. If special circumstances arise, it can be stipulated separately as required.
(5)The elevation of the crane's installation and use shall not exceed 2000m (the motor capacity shall be checked according to the relevant provisions of GB755 when it exceeds 1000m).
