Guardrail pile drivers are used for the installation and construction of crash barriers. If a safety accident occurs during construction, the foreman and the operator are the ones who suffer.

Given the current industry situation, the responsibility system is not well established. Most guardrail pile driving machine operators are directly employed by the machine owners, and this labor relationship is merely based on a verbal agreement. While most machine owners rent out their guardrail pile drivers to construction sites, they only agree on the rental fee and payment matters of the machinery and equipment. There is no contractual clause to stipulate how much responsibility each party should bear, which lacks protection for the operator, machine owner, and constructor. In the event of an accident, besides the financial loss, there might also be the cost of human lives, and the machine owner's daily operations would be affected, subsequently delaying the project progress.

In most construction accidents, the construction party and the site manager ultimately bear the responsibility. However, for the construction party and manager of the guardrail pile driver, it is the construction team itself. Thus, in the event of an accident, it is not only a loss of property but also a serious threat to the safety and property of the construction personnel.
