Note: strict compliance with safety procedures, to eliminate chances when used in strict accordance with GB17620-1998 standards before using the operator should carefully check the insulation ladder body and parts, with or without defects or cracks. Wide Receiver is solid, various accessories are loose, etc., to prevent accidents. Prevent moisture damage, so as not to affect the insulation level. To ensure safe and reliable product performance, shall be on an annual cycle of performance testing. Insulation ladder main technical requirements: (a) the appearance, the assembly 1. View Appearance: ladder components shall not have sharp edges and corners shape should be inverted arcs. 2. Assembly: YB3205 should meet the requirements of (two) General requirements 1. Raw materials should be pre-tested 2. Aluminum alloy parts should be done anodized surface, shaft steel surface should protective coating; insulation class materials, parts machined surface laminated insulating paint application for processing. 3. Metal part surface roughness should be ≤ 6.3 parts machined surfaces should be rules and smooth. Insulating parts surface should be smooth, no bubbles, wrinkles or cracks, abrasions and no obvious signs of overheating, the color should be natural color (from yellow green to brown) in the power production operations to use insulated ladders, prohibit the use of aluminum and other metal ladders . (2) physical fatigue, medication, alcohol or physical obstacles, prohibit the use of ladders. Prohibit the use of a ladder in a strong wind. High-temperature electrical insulation ladder polymerization pultrusion manufacturing process, material selection epoxy joint pin rod technique. Aluminum alloy parts made anodized surface, shaft steel surface with a protective coating; insulating laminated type of material parts machined surface treated with a varnish. Stepladder support, stepladder feet slip design fatigue, stepladder shape without sharp edges and corners of each component, secure a high degree of insulation performance; low water absorption, resistance to corrosion.
