Redco Truck Charge Hopper & Discharge Chute Liner

Mixing concrete is a difficult process, and is especially taxing on your mixing equipment. In recent years, the value of lining equipment has become readily apparent; however, if you’re not using the proper lining materials, lining your equipment can cause excessively long shut-downs.

Urethane liners resist sticking and build-up inherent with rubber and steel type liners, provide easier cleanup, and wear longer than steel.

  • Fast, Bolt In Installation
  • No Seams to Disrupt Flow or Collect
  • Provides easier loading of Mixer and less time at the slump rack.
  • Lightweight and outperforms steel.
  • Economical?protects metal hopper and main chute against wear.


Redco Urethane Pan Mixer Liners

Protect your pan liner and reduce maintenance cost with a Redco Urethane pan mixer liner.

  • Ease of clean-up between batches (breaking loose dried concrete)
  • Reduce or eliminate sticking and buildup
  • Can outlast steel liners by 2 – 4 times
  • Reduces noise levels
  • Reduced downtime and maintenance


Redco Urethane Wear Pads

Redco Urethane Screw Conveyor Flight Wear Pads are the solution to the abrasion problems inherent in screw conveyor applications. The advantages to urethane wear pads are:

  • Urethane won’t rust or corrode
  • Lightweight = easy to install with less wear on equipment
  • Redco urethane classifier shoes will return to their original shape if bent or distorted
  • Available in a variety of styles and replacement sizes

Pads & Bumpers

Redco Pads & Bumpers

Redco Pads & Bumpers Constant banging and scraping will wear out equipment prematurely. Redco Plastics are engineered for the toughest applications to absorb impact and prolong equipment life. We have developed numerous parts for trucks and shovels such as:

Redco Body Pads, which have been designed to replace traditional rubber pads, provide longer wear life and dont permit the impregnation of rocks. The pads bolt or weld directly to the bottom of the truck box to protect the frame from shock, vibration, and wear.

Redco Urethane Bumpers, which are available in many custom sizes, protect the truck body from banging ladders, wheel chocks, etc. while the truck is in motion.
