Maintenance Tips

Rule No. 1
Do Not Push A Belt!

Drive units should always be installed at the discharge end of a conveyor. In this manner the conveyor belt is more easily PULLED in a straight line as opposed to being PUSHED. Following this one simple rule will eliminate many belt tracking problems.

Belt Storage

To prevent belt from developing camber (curve), rolls should be stored off the floor in a dry area. They can be suspended on a bar pushed through the center of the roll, or placed on a pallet or skid to keep roll of the floor. Rolls should NOT BE STORED ON THEIR EDGES because the edges of some belts may absorb moisture from surfaces in which they come in contact. This causes the edge to shrink and become tighter than the opposite edge, resulting in a crooked belt.

Belt Failure

Belt failure occurs when fasteners are stronger than belt and pull out by combing through belt fabric. Prior to failure, holes behind hook legs will become elongated. After pull-out, hooks will remain in fully clinched form and frayed belt fabric will be visible on belt ends. ANSWER: Check for use of proper size hook (hooks may be too big for belt thickness); Stronger belt may be needed for this application; or possibly need a hook with a longer reach-back.

Hook Failure

Hook failure occur when tension loads exceed fastener strength. In this case hooks will open up in varying degrees (usually starting on one side of joint) and let go of the belt. Increased strain caused by such things as belt being caught on or hitting conveyor structure or quick tension overloads may result in hook failure. ANSWER: Check for use of proper size hook (hooks may be too small for belt thickness): Check for belt tracking problem; or possibly use a stronger high-tensile hook.

Installing Fasteners

Choose the fasteners size on the basis of the overall belt thickness and the overall belt thickness and the diameter of the smallest pulley in the drive. Generally use the smallest fasteners that will fit the belt thickness. Fasteners size can sometimes be reduced by recessing. Various hinged fasteners can be used to accommodate small pulleys or plate fasteners can be installed on an angle. lake sure that ends of belt are cut perfectly square, otherwise the belt will not track properly. Some fasteners require special hand tools or templates which we can supply.
