Sliding plate drill rod fall protection system

During up-hole drilling, a centraliser, using hydraulic force, holds the rod while the next drill rod is being inserted. It is very important that the rod doesn’t slip as it can cause serious damage to the drilling equipment or injury to the operator. To protect the equipment and operator, a sliding plate drill rod fall protection system could be installed as a fail-safe. The sliding plate assembly has to withstand the weight of the rod string including a safety factor. One such sliding plate was designed by Dynamic Engineering in conjunction with the client. The analysis was done to check that it complies with the Australian standard and is strong enough for the weight of the rod string.
