THE PROBLEM
FUGITIVE MATERIALS
Escape of materials from conveyors is an everyday occurrence. It occurs in the forms of spillage and leakage from transfer points or carryback that adheres to the belt past the discharge point and drops off along the conveyor return. It also occurs in the form of airborne dust that is carried off and settles on structures, equipment and the ground.
Carryback falls under the conveyor, spillage falls to the sides and dust falls on everything, including systems and structures above the conveyor. Left unchecked, fugitive materials represent an ever-increasing drain on a conveyor’s efficiency, productivity and profitability.

Reduced operating efficiency
- Increased conveyor maintenance costs
- Reduced plant safety
- Lowered employee morale
- Diminished product quality
- Heightened scrutiny from outside agencies
THE MARTIN® SOLUTION
Through proper design and maintenance, bulk material handling operations can run cleanly, safely and efficiently.
By preventing spillage and airborne dust, Martin Engineering’s Transfer Point Products can help reduce equipment damage, reduce cleanup, control maintenance expenses and improve the overall plant safety.
Martin Engineering is more than an equipment supplier. We are problem solvers dedicated to improving transfer point performance.
KEY COMPONENTS
(1) BELT SUPPORT
For an effective, minimum-spillage transfer point, it is essential that the belt’s line of travel be stabilized with proper belt support in the load zone.
(2) SEALING SYSTEM
A crucial requirement in any transfer point designed for reduced spillage and high efficiency is an effective sealing system at the edge of the belt.
(3) BELT TRACKING
Belt tracking must be controlled before spillage can be eliminated.
(4) TAIL PULLEY PROTECTION
Pulley protection plows are installed to remove lumps and stray components from the remove lumps and stray components from the belt before they can damage the pulley or belt.
(5) CHUTE STRUCTURE
Bulk materials should flow through a transfer chute evenly and consistently
(6) DUST MANAGEMENT
Airborne dust is a common problem in bulk-materials handling operations. When both material spillage and airborne dust are controlled, the operation will be cleaner, safer and more productive.
BELT SUPPORT
MARTIN® IMPACT CRADLE
Installed under a belt conveyor loading zone, the Martin® Impact Cradle absorbs the force of falling material to prevent damage to the belt and structure. Wing supports adjust to match any standard trough angle. An additional five degrees of fine tuning adjustment enables the cradle to match the idler profiles of different idler manufacturers. Rugged bars are composed of a top layer of low friction UHMW and a lower layer of energy-absorbing polyurethane.
MARTIN® HIGH-SPEED IMPACT CRADLE
Designed and engineered for high speed / high tonnage belts, Martin® High Speed Impact Cradles provide belt support in transfer points where belt speeds exceed the operating limits of ordinary impact bar belt support cradles.
MARTIN® MODULAR SLIDER CRADLE
Eliminates pinch points where trapped material can gouge or tear the belt and stabilizes the belt’s path to improve sealing and tracking. Low-friction UMHW bars support belt edges to stabilize the belt line, eliminating belt sag and bounce. Proprietary “box” design allows each bar to be turned over to provide a second wear life.
SEALING SYSTEMS
APRONSEAL™ SKIRTING
(quick release clamps)
Provides dual-seal efficiency with a single, one-piece sealing strip for any troughing angle to prevent the escape of fines and dust.
ApronSeal™
Double Skirting uses a patented design that features a reversible elastomer strip to provide a second wear life.
Optional quick-release clamps are available.
MARTIN® SELF ADJUSTING SKIRTING
Self-adjusting skirting system rides the belt to create an effective seal automatically. Requires only six inches (152 mm) of clearance and only 1.5 inches (38 mm) free belt area for sealing. “L” System has an inward extension under the skirtboard to increase the range of tolerance for belt mistracking. A lso availabe in Urethane XHD profile.
belt cleaners
CleanScrape® Primary Cleaners
Installed at an angle across the discharge pulley, the revolutionary CleanScrape® Primary Cleaner requires minimal space for installation. Because the CleanScrape® Primary Cleaner is equipped with tungsten carbide tips and applies minimal pressure to the belt, it’s safe for use on mechanical splices, making it the most versatile belt cleaner on the market.
CleanScrape® Secondary Cleaner
The CleanScrape® Secondary Cleaner is an all stainless steel assembly featuring independent 6-inch wide blades with carbide tips. Each tip is supported on spring-loaded arms at both ends. The load springs allow independent blade rotation back and forward as well as up and down. This range of motion provides equal load pressure across each blade, absorbs obstructions, conforms to ever-changing belt undulations, and is able to arc safely in the event of reversing belt direction or belt rollback.
QC1+™ Cleaner HD
The Martin® QC1+™ Cleaner HD is a patented new evolution in belt cleaner technology designed to help your operation achieve a higher level of productivity while simultaneously reducing costs! It is guaranteed to provide you with the highest performance and the lowest cost of ownership of any urethane precleaner.
