The GMP series features a dual-cylinder main engine of the same specification, equipped with a dual-machinery联动 synchronization device. The dual-machinery联动 bending machine is capable of processing long-span workpieces, particularly for urban construction, automotive manufacturing, highway lighting poles, power poles, and other long-span workpiece manufacturing. Both machines can be used individually or in tandem. Optional workbenches with hydraulic compensation are available to eliminate bending side compensation and bending side deflection deformation.
