Large cranes consist of ground tracks, mobile base units, systems, beams or booms and trolleys. Further tracks are made by the mobile base unit, load manipulation with the trolley.
The mobile base unit and the trolley are partly equipped with flange wheels or/and supporting rollers. Those run on trails, are driven by electric motors and because of friction wear are exposed to large charges at the contact point between wheel and trail.
Port operations, timber industry, cement-, lime-, gypsum industry, plaster and mortar industry, chemical factories, paper mills, aluminum and steel plants, sugar factories, quarries, raw material industry, etc.
Problems on treads:
High wear on rails and wheels on the tread or head rail, loss of friction due to hardening of rail (danger of slipping, unknown braking distance, starting slip, slip-stick effect), high costs and long waiting times for rail repair (welding, grinding, changing), wheel change (trolley is in a height of 30m!!)
Solution for tread on ground track and trolley:
Equipment with adhesive blocks 10035 in mountings H015. Those coat maintenance-free with adhesive agents to maintain the constant friction between wheel and rail (dynamic coefficient of friction of 0.3-0.5). Simultaneously wheels and trails are protected from wear. The operating life should at least double. Convenient side effects like higher smoothness and freedom from maintenance occur when using wear protective adhesive blocs 10035.
Problems wheel flange:
Shrinkage of rails on flanks, shrinkage of wheels, tendency of wheels to “climb“ (Wheel flanks seize on rail flanks and climb). High costs and long waiting times for rail repair (welding, grinding, changing), wheel change (trolley is in a height of 30m!!).
Solution wheel flange:
Equipment of wheel flanges with lubricating blocks HG04511 in mountings H011. The wheel flanges are maintenance- free coated with dry lubricant. The wheel sets and rails are protected from wear.
The dangerous ”climbing” of the wheels is prevented by an extremely hard and dry lubricant film. The operating life should double. High time and cost saving because maintenance intervals for wheels and rails are minimized.
