To protect workers from all areas of conveyor systems that create a safety hazard, yet allow for easy removal of conveyor guarding, and replacement, when maintenance on the conveyor system is required.

By using various standard sizes of the ASGCO Safe-Guard Modular Conveyor Flat Guards, we were able to protect the hazardous areas and still allow them access as needed by easily removing and replacing the lightweight powder coated panels.

At this copper mining operation, the return idlers that track the belt on the conveyor system were very hard to access. The only way to change the idlers on this 36” wide conveyor belt, was to clear out all of the material on the ground and rent a 135’ man lift to access the conveyor belt tracking return idlers.

A ready-mix plant had difficulty properly tracking the vital conveyor belt that feeds the mixer. The problem was essentially that the conveyor belt was difficult to keep in alignment, which caused serious belt edge damage, and in turn de-lamination and spillage in the conveyor load zone.

A copper mine was experiencing high wear in their "pant-leg" chute liners. A combination of abrasive material and high tonnages was the major factor why the mine was only about to get 4-5 weeks from 1” thick AR500 plates.

This transfer point was a major problem area for the coal company. While in reclaiming operation, the chute would build up and plug when running wet coal or during freezing conditions. Chute heaters, vibrators and internal baffles were added but the problem still remained. Due to the angle of discharge onto the 60” receiving conveyor, off center loading caused serious belt miss-tracking and constant spillage.

While discussing the challenges with key employees, and doing a thorough analysis of the plant, we discovered some of the problems that were occurring, including; issues with conveyor belts not getting cleaned properly as well as tensioning systems on the primary belt cleaners locking up (or taking a set) and causing major material carry-back problems within the plant.

Problems of continuous misalignment on a short reversing feeder conveyor belt was causing severe damage to the belts. These were replaced monthly at a cost of $741 USD/each belt, however, down time is $73,059 USD per hour and the replacement of this belt needs a time of 4 hours. That is the equivalent to $292,237 USD of downtime related to the conveyor.
