John is an experienced construction machine operator working in South Africa, especially good at operating rotary drilling rigs. The construction team he is in charge of recently undertook a large infrastructure project in the suburbs of Johannesburg, South Africa. The complex terrain of this area, with not only soft soil but also a large number of hard stones, places high demands on the durability and stability of the machinery.
To ensure the project went smoothly, John worked as fast as he could, but after three weeks of intense construction, John noticed that the tracks began to occasionally buckle on steeper turns, especially in areas with a lot of gravel.
Although the problem did not affect the overall construction, John was concerned that if it was not dealt with in a timely manner, it could have an adverse effect on the long-term use of the equipment.
Out of an abundance of caution, John decided to contact the supplier of the rotary drilling rig’s track assembly, Yantai Orient Heavy Industries, for professional help. John had cooperated with Yantai Orient Heavy Industries many times before.
This time, John’s customer service not only patiently inquired about the detailed usage and the geological condition of the site, but also immediately arranged for a technical engineer to remotely help with the on-site inspection.
After the cooperation between the engineers of Yantai Orient Heavy Industries and John’s on-site team, they found that the problem originated from the long-term friction between the sharp stones in the soil and the tracks at the construction site, which led to the serious wear of some of the track links.
The track assembly needed to be replaced. Before the new track assembly could arrive, the engineer instructed John to perform on-site maintenance on the tracks and adjust the track tension. This ensured that the machine was not shut down and minimized the impact on the project schedule.
When the new track assembly arrived, John replaced it under the guidance of the engineer. This time, the supplier provided John with a customized track assembly with improved wear resistance and hardness. The engineer advised John to clean and inspect the track chain regularly, especially on sites with a lot of mud and gravel.
In addition to this, the supplier also promised that if the problem reoccurred, they would provide a free replacement within one year. This promise gave John and his construction team a great deal of peace of mind.
This rotary drilling rig has performed well in the complex environment of South Africa, and the service attitude of the supplier has given me confidence in future projects,” John says with satisfaction. We are confident that we can work with such a reliable company!”
