The overall planning of the steel grating of the working route and safety passage should avoid the danger caused by falling objects. There are no vacancies beyond the static free space of the steel grating. The static space of the steel grating in the working path or safety passage should not allow the ball with a diameter of 35mm to pass through.
The passages and safety passages above the manned place should not allow the ball with a diameter of 20mm to fall through the static space of the steel grating. Otherwise, other appropriate equipment should be selected to ensure the same safety level. The overall planning of steel gratings for working paths and safety passages should avoid the danger of falling over non-motor vehicles. The large aspect ratio difference should not exceed 4mm.
To avoid the risk of falling of the steel grating, in order to avoid the risk of falling, the machinery and equipment of the steel grating should be fixed as much as possible by the welding process. The steel grating shall be machined and installed according to the prefabricated components of the steel frame structure tablet computer. After the machine is installed, it shall not be moved horizontally or removed from the support frame. 25mm.
The steel grating that requires thematic activities and dismantling must be fixed with a special type of machinery and equipment fixtures for steel grating. Avoid all movement of the prefabricated components; the machine clips can be supplied by the manufacturer according to the buyer's request. Except for the machine clips made of stainless steel, the carbon steel machine clips must be hot-dip galvanized metal surface treatment, it is recommended The anchor bolts for machine equipment clips shall be treated with hot-dip galvanized metal surface. The diameter of the anchor bolts shall not be less than 8mm. The total number of machine equipment clamps applied to each steel grating shall not be less than 4.
