Yes. There may be other parties responsible, such as engineers who were involved with the original design of the machine or people or entities responsible for the machine after it was made. Industrial machines are often used for many many years. Throughout an industrial machine's lifetime, upgrades and maintenance are often performed. If an outside engineering company was brought in to upgrade the machine and did it improperly, the engineering company can be liable for injuries sustained by a machine operator.
Therefore, a careful and thorough investigation of the parties or contractors involved with the design, upgrade or maintenance of the industrial machine is necessary to identify the potential liable parties.
