Slider Cradle

Installed under the skirtboard of a transfer point, Martin® Slider Cradles support the edges of the belt to eliminate sag. These cradles prevent transfer point spillage by stabilizing the belt’s path and allow the effective sealing of the belt edge. Cradles are available with high-performance UHMW or Stainless Steel Bars to match application requirements.

Features and Benefits:

  • The Martin® Slider Cradle supports the belt edges, allowing an effective seal
  • Slider Cradle eliminates pinch points where trapped material can gouge the belt
  • Conveyor belt glides over UHMW bars without heat buildup
  • Use both top and bottom of unique "box bar" to provide dual-wear surfaces for double wear life
  • Slider Cradle adjusts for wear easily with simple tools
  • Fits any troughing angle. One bar per side for belts 18 (457 mm) to 42 inches (1067 mm); wider belts require two bars per side. Center bar or rollers may be required.
  • Protected by U.S. Patent No. 4,898,272

Belt Support Products Solve Fugitive Dust And Spillage Problems
A coal plant had spillage and dust issues at two conveyor transfer points, because material was loaded onto the belts traveling 500 fpm with little control over impact or settling. The result was excessive fugitive dust throughout the facility. Inadequate chute control caused spillage to get caught between the belt and rubber tail pulley, damaging both.

Martin Engineering Offers Dependable Solutions When Others Fail
A mine was experiencing dangerous spillage at the loading zone of its tower mounted conveyor. Despite installing equipment from a previous supplier, workers found that dust filled the tower and chunks of raw material spilled from the transfer chute onto the stairs, creating a potential workplace hazard. Twice a month operations had to be disrupted for 12 to 24 hours, so that a 4 to 5 person team could clean spillage.
