Last scaffolding steel pipe straightening machine paint rust, five patents. Workspace of a machine two, three functions can be used simultaneously but also cross each other or separately jobs. A separate tune straight hydraulics, the dedicated 48mm frame tube repair, regardless of the medium and large hard curved lateral bending of the rebound coefficient based on the pipe once one meter to complete a one-time only 2 seconds, and do the hard bend and slightly flattened shape local repair. 1-6 m tube can be adjusted directly. Rust by 30 damping wire rope brush surrounded by steel pipe, rust, ash can be clean and no damage to steel pipe. 2-6 m steel pipe alone rust, and paint at the same time a one-time auto-complete, 6 m steel pipe for only 50 seconds. Painting outside diameter range of 30-58mm. Other model wire rope bristles can not shock absorption and ineffective and injury steel and low efficiency drawbacks. To follow up automatic painting device, the implementation of the paint splash, do not waste paint uniform level without dripping, etc.. Solve the artificial spray, brush paint uneven and low efficiency.

Thrusting brushes, adjustment and simple cleaning. Ordinary paint brush market do. Work is completed, the valve is released, leftover paint recycling drums is very convenient.
