- Roller cradle lifting capacity, it depends on beam material, beam welding and steel rope etc

- Roller cradle safety factor: 5:1

- Roller coating life time: urethane rollers eliminates the risk of damage to the pipe

Deping adopts high strength welding steel as hanger material of roller cradle to ensure welding seam strength

Key factors for roller life time: coating process and coating thickness.

To prevent coating peeling out, Deping well organize the coating process of pipe roller cradle, including: metal roller polishing, sand blasting, 2 times of ultrasonic cleaning, drying, applying glue, heating treatment in oven, keep dry and metal roller at constant high temperature for coating, coating vulcanization for 24hours etc.

Furthermore several coating tests will be conducted per standard DIN53505 or GB/T 528-2009, including Hardness shore A, Max. broken pulling force / N, Tensile strength / MPA, Elongation at break / %, Peel strength / N/mm etc.

Deping’s pipe roller cradles comply with European standards, obtain CE certification.
