Confirming and holding the position of the coils in the hot coil water-cooling pool, as well as lifting them, is a dangerous and difficult task. This product recognizes the holes through sensor penetration detection when the lifter descends and automatically stops where there is a coil hole. The arm closes and inserts claws into the coil hole. When the coil is lifted, the stock detection sensor activates, and a safety device operates to prevent the arm from accidentally opening and dropping the coil during transport. In addition, various safety measures are incorporated into the design to support 24-hour unmanned operation.

Four Steps to Formulate a Procurement Preservation Strategy 1. Review of Procurement Scope: Materials, Cut Products, Semi-finished Products, Component Parts, Finished Products Identify internal and external strategies in light of the company's manufacturing processes. ◎ Equipment capacity and worker issues → Include inefficient in-house tasks in procurement. ◎ To enhance internal added value, focus on in-house production and select materials that improve work efficiency. 2. Development of Procurement Specifications and Drawings for Procured Items, Consistency with Supplier Supply Scope Not all required specifications are easy to express. Establish a mechanism for confirming order specifications with suppliers. 3. Quality Development: Understanding the Supplier's Quality Control Capabilities and Manufacturing Processes 4. Performance Verification: Establish a mechanism to verify the performance of finished products Ensuring quality is the top priority. Based on that premise, secure the necessary quantities and delivery times. Regarding price, negotiate sincerely considering each other's business opportunities.
