Wheel static balance test day: the day after spot welding wheel again placed on the slide, the light switch to heaven sheave wheel manufacturing plant, if welding counterweight to the following point, you can remove the counterweight lift sheave sheave without adjustment to meet the requirements; if coupled with a counterweight sheave blocks onto the slide light switch sheave, after days of round stoppage and the relative angle before welding unaltered Henan lift sheave manufacturers, indicating center of gravity Offset is too large, then need to be adjusted to balance the construction of Shandong lift sheave, can be drilled, add weight and other means. Mine Tianlun scope and features: Mine shaft sinking sheave mounting on the derrick, as a support, support drag between the container hoist drum to enhance the time for mine hoist, wire rope guide steering purposes. Rope groove with plastic lining or plastic block, increase the service life of the rope. Mine shaft sinking sheave wheel only rotates.
