National StandardCD、MD Series Electric Hoists (0.5-20t)Product Introduction: The National Standard CD and MD electric hoists are electric hoists with a reasonable structure, convenient assembly, and superior performance. The lifting capacity ranges from Gn=0.5 tons to 20 tons, with a lifting height of 6m to 30m (up to 100m). The ambient temperature is below +40℃, and the working system is 25%. These are light crane equipment. This product is widely used in factories, warehouses, logistics, and other applications. It also meets GB/T standards. 10051-2010 "Electric Hoist" and GB 6067.1-2010 "Safety Rules for Lifting Appliances Part 1: General Principles" standards.　Technical Features: Three-in-one rotating system, electrical contactless module speed control, and the ability to achieve micro-speed and dual-speed proximity frequency conversion functions, ensuring particularly smooth operation, lifting, and inching. Equipped with overload alarm, anti-skew and anti-tilt protection, anti-hook impact protection, and phase loss and overcurrent protection, the control console (handle) uses 12V safe voltage, thus achieving multi-functional protection for the hoist. The electric control can be used for up to "2 million" operations when the voltage is within 380V±5% to 380V±10%.　Modular Design: Components are easy to disassemble and maintain, such as the motor and reducer, which can be quickly separated.　Structural Design: Balancing reliability and economy in conventional industrial applications, making it an ideal choice for small and medium-tonnage lifting tasks.　Compact and Lightweight: Optimized structural layout, suitable for spaces with limited constraints.　Protection Level: Motors and electrical components typically meet IP54 standards, providing dust and water resistance and adapting to harsh environments.　Performance Parameters:　Lifting Capacity: 0.5 tons to 20 tons; Lifting Height: 6m to 30m (up to 100m); Working Level: A3 to A4　Main Components: (Lifting Motor; Hoist Runway; Rope Guide; Hook; Overload Protection)
