Basic requirements 1, hoist shall comply with the requirements of this standard JC460.1 and bucket elevator manufacturers, and design drawings and technical documents in accordance with procedures approved by the provisions of the manufacturing, installation, and use of the standard production bucket elevator, drawings and technical documents Technical requirements are not specified, according to common standards concerning building materials machinery, mechanical and electrical industries, such as the implementation of .2, tolerance did not note the size of the pattern deviation limits shall conform bucket elevator GB 1804, in which machining surface tTl3 level; weldments non-machined surface ITl6 level; forging of non-machined surface .3 ITl5 class manufacturing, welding shall comply with the relevant provisions of building materials machinery welding .4, gray iron castings shall comply with the provisions of .5 GB 9439, forgings shall have mezzanine, folding, crack, satin injury, scarring, slag and other defects .6, hoist should be set level meter, monitor and tape speed anti-deviation device. Model selection as common lifting equipment, hoist bucket chosen by many factors constraints bucket elevator chain plate, using the wrong model will bring untold trouble parties. General decided bucket elevator selection depends on the following factors: 1, shape material: material is powdered or granular or small block. 2, the physical properties of materials: Material has no adsorption or viscosity, whether moisture. 3, the proportion of materials: general bucket elevator parameters are for bulk density in the material design and calculation of 1.6 or less, and much of the proportion of the material needs to be part of the tensile strength of traction and transmission calculations. 4, delivery amount per unit time.
