Overall structure of the crane
1. Adopt European structure, which can adapt to 7 × 24h working conditions, optimize the design, with large safety factor, high strength, fatigue resistance, impact resistance, beautiful appearance, automatic operation and emergency manual operation.
2. Imported configuration automatic spreader roll can pick up the paper roll through six evenly distributed friction pads, which has a gentle gripping force and smooth motion. It can minimize the deformation and damage of the paper roll; One-stop rail transportation reduces the transportation cost and shipping time.
3. The gripper can be fixed by the gripper frame. In this way, it will avoid shaking during operation, ensure accuracy, and increase efficiency.
4. Horizontal size wheel device for cross traveling and long traveling can ensure stability during high-speed operation, avoid wheel track and skew running.
5. Compact transmission mechanism, lift motor with absolute encoder, can guarantee a large torque output at low speed, with the automation system, to ensure a high positioning accuracy, and the spreader does not appear to slide, so that the clamping and placement to be more accurate.
6. The operation is F series three-in-one driving mode. The brake motor is equipped with an absolute encoder, which is matched with the automation system to facilitate the positioning of the running mechanism in the horizontal/longitudinal direction. The braking method adopts a magnetic disc brake with manual release function.
