What are the requirements for the installation of overhead basket?
Safety requirements for overhead operation basket 1, unified safety requirements for overhead operation basket, relevant standards: GB19155-2003 "hanging basket for height work". 2. The basic structure of overhead hanging basket is divided into three parts: suspension platform, wire rope and suspension mechanism. The front end of the suspension mechanism is provided with a rear counterweight to overcome the overturning moment at the front end. The steel rope is hung on the hanging mechanism, and the steel rope is divided into a work rope and a safety rope. Hoist for electric and manual, general electric climbing type, wire rope hoist is wound in a circle, hoist and hoist platform connected with the steel wire rope climbing platform. Safety at work rope break when the suspension platform lock on the safety rope.
3, gondola suspended platform structure and safety inspection requirements: 1) safety lock type consists of swing arm type, centrifugal type anti tilt speed. Swing arm type anti tilt lock, suspension platform when the longitudinal inclination angle of not more than 8 degrees, can automatically lock and stop running; centrifugal trigger type safety lock, suspension platform running speed of 30m/min lock rope speed, which can automatically lock the safety rope.
The suspension platform shall be marked with the rated load and the emergency stop button for cutting off the main power control circuit in the emergency state. The circuit is independent of each control circuit. The emergency stop button is red, and there is a "stop stop" sign. It can not be reset automatically. The electric system must be equipped with overheat, short circuit, leakage protection and so on
The basket should have enough strength and stiffness. When the basket is subjected to 2 times the rated load, no weld seam crack, bolt rivet looseness and structural member damage shall be allowed. Hanging around the platform shall be equipped with safety fence fixed, guardrail should be equipped with the web bar, guardrail height should not be lower than 0.8 m, the remaining parts of the body should not be less than 1.1 m, 1000 N guardrail should be able to withstand the horizontal concentrated load. Suspension platform working width should not be less than 0.4 m, and shall set up anti-skid floor, floor drain hole diameter of 10 mm. suspension platform around the bottom shall be provided with a height of not less than 150 mm plate, longitudinal tilt angle gap baffle and a bottom plate is not greater than 5 mm. suspension platform at work should not be greater than 80, lifting platform should be provided the wall round or guiding device or buffer device.
