1. This is a product with several patents, this product is hydraulic, and has a two-speed bending and bending function of the dual purpose machine. It has two control modes: foot control and automatic transmission. 2. The quick and slow bend functions can be easily switched without turning off the power. Foot control mode does not need to adjust the machine, with the time of stepping foot switch can control the angle required by bending. More powerful and more convenient operation. 3. The configuration is our company's first research and development of double variable oil cylinder, its oil temperature is low, so that the machine running more powerful and faster, bending rebar more easier.
