During the removal of communication cables and similar items, the lifting and cutting operations are performed automatically. Since the removal machine is set at the rear of the truck, the cut cables fall to the back of the cargo area, eliminating the need for loading work. This allows for efficient and speedy operations, reducing the labor, personnel, and time required for workers. You can choose to fix the cable removal machine (KSR-75) to the vehicle or opt for a detachable version. By making it detachable, the main unit can be used as a truck when removed. *We offer vehicles in both unic type and small trucks (with PTO), allowing you to choose according to your needs. 【Features】 ■ Automatically performs lifting and cutting operations during the removal of communication cables and similar items ■ The removal machine is set at the rear of the truck ■ No loading work is required ■ Enables efficient and speedy operations ■ Reduces labor, personnel, and time for workers *Available for online business negotiations!
