I. Introduction of equipment

CR4G-UHP 380 hull derusting robot integrates ultra-high pressure water jet paint removal, vacuum adsorption and wall-climbing robot operation. Easy to operate, high degree of automation, through the operator standing on the ground, handheld pneumatic controller can control the robot in the hull facade X, Y direction arbitrary walk.

CR4G-UHP 380 hull derusting robot adopts 4-wheel drive, gantry layout (cleaning tray in the middle), suitable for shipyards, marine engineering, petrochemical and other industrial fields, providing more advanced solutions for steel surface treatment.
 
II. Performance characteristics

1, using ultra-high pressure water stripping technology, the working pressure can reach 2800 kg/cm2; after stripping coating, can restore the steel plate sandblasting surface Sa2.5 whiteness;

2, using the principle of magnetic adsorption and vacuum adsorption combined, innovative structural design does not need to rely on any lifting tools or equipment, can carry 150~200kg load, adsorption on the steel structure facade wall or ceiling, freely crawling;

3, four-wheel drive, with a certain 3D surface through the ability, as well as convex and concave surface and weld obstacle ability;

4. Wireless remote control system, safe, clean and efficient, can be operated by one person;

5. Flexible recovery shield and brush shield to prevent jet overflow and strong ability to adapt to curved surfaces;

6. Self-developed integrated differential to adapt to high torque operation;

7, corrosion and protection level is high, adapt to all-weather field operations.

III. Equipment advantages

1. Compared with water blasting cleaning and manual ultra-high pressure cleaning, this method is faster, safer, environmentally friendly, economical and efficient;

2, with our company's high-performance ultra-high pressure pump station, rust removal efficiency can reach 85㎡/h;

3, vacuum recovery interface integrated in the anti-splash shield, negative pressure adjustable, can be connected with the ground recovery equipment, paint residue and sewage will not leave the steel plate surface;

4. Innovative steering mode, independent steering of front and rear wheels, simultaneous steering, lateral movement, three steering modes switching each other, can smoothly enter or leave the obstacle dead zone;

5, adsorption type automatic wall-climbing robot can be strongly adsorbed on the metal surface, and can move on its own. No cranes or lifts are required for loading and unloading;

6, robot controller, with remote control, can communicate with the robot and control the robot, high reliability; remote monitoring image system, convenient for remote observation and night work.
