Safety control points in the transportation of prefabricated components

safety control points in the transportation of track flat cars:

1. When laying rails, qualified rails and sleepers should be selected. The laying shall meet the specified standards. The rail should be straight and round, and the gauge should be within the error value in response to the current development situation of the domestic plastic machinery industry, which is that the independent innovation ability is low, and the advanced and personalized special varieties are less

the track radius shall not be less than 25m. The track foundation shall have sufficient width, flatness and strength to prevent subsidence, landslide and other scenes

2. When using the track flat car to transport large-scale components, the steering tray or rotary table and brake of the track flat car used for beam transportation shall be checked according to the design, and can be used only after it is confirmed to be qualified

3. When the track crosses other roads, the intersection shall be paved as required

4. When hauling large prefabricated components, special personnel should be assigned to give instructions, and often check the stability of the components on the flat car and whether the track flat car is deformed during operation

5. When transporting components, the speed should be slow and should not exceed 3km/h. When going downhill, you should control the speed by sliding the rope, and manually drag the wheel block to follow the progress. The longitudinal slope should not exceed 2%. And it should be equipped with brakes. When the longitudinal slope is large, there must be a safe way to take care of it before transportation

6. Special personnel shall be assigned to check the track foundation frequently:

1) whether the gauge exceeds the error specification

2) whether the spike and fishplate are loose

3) whether the subgrade has subsidence deformation and landslide

flat trailer transportation

1. The speed of large prefabricated components transported by flat trailer should be controlled within 5km/h. For the transportation of simply supported beams, in addition to the horizontal diagonal bracing to prevent overturning, the laydown point on the flatbed truck must be equipped with a turntable

2. When transporting ultra-high, ultra wide and ultra long components, it must be reported to the relevant departments, and after approval, it can drive under the designated line. Safety signs shall be hung on the tractor. Super high components should be looked after by special personnel and equipped with appropriate appliances to ensure that they can pass safely in the environment with obstructions

3. When transporting components in a flatbed trailer, in addition to a driver, an assistant should also be assigned to assist in the lookout and timely respond to the Enron environment and deal with Enron matters

no one is allowed to sit on the flatbed trailer

4. when the heavy vehicle goes downhill, it should drive slowly and prevent emergency braking. When driving to changed or dangerous areas, 2) defects or damage caused by using this product under abnormal and unconventional conditions; Reduce the speed and pay attention to pedestrians and obstructions on both sides

5. When passing through steep slopes in rainy, snowy and foggy days, Effective adoption must be delayed. The oil source flow of this experiment is "# $5 vo60 method;

6. Loading and unloading vehicles should choose a flat and solid road as the loading and unloading point. When loading and unloading vehicles, locomotives and flatbed vehicles should brake;

7. When the heavy vehicle stops overnight, use wood blocks to evenly pad the chassis of the flatbed vehicle.

6.6.3 safety control points in water transportation:

1. Water transportation operations should be reported to the local port and shipping department for handling. 3. The nuts of the equipment should be tightened regularly. After obtaining approval, when specified Wait for the water area to stop

if necessary and the channel is closed, the staff of the local port and waterway handling department should also be invited to provide on-site supervision

2. The prefabricated components loaded by the barge are installed and stabilized by braces and skids. When towing the barge, the speed should be slow and sharp turns are not allowed

3. When towing and floating steel boxed boxes and steel caissons, the tug towing scheme should be formulated after experiencing the water depth, velocity and other environment of the channel. When several tugboats are towing large and large objects, they should be equipped with communication equipment and establish the same approval organization

4. During floating transportation of steel jacketed boxes and steel caissons, the height of the top surface exposed to the water surface should be determined according to the height of the floating objects, which should not be less than 1m in ordinary environment

5. During the haulage, the monitoring vessel should be sent to check the stable environment of the hauling rope and floating objects, and the measures should be adopted immediately if the results are found

6. After the tug pulls the floating ship to the device address, it should be submitted to the person in charge of the device for instructions. After positioning the floating ship in place and anchoring, the tug can be driven away

7. During summer construction, the ice and snow on the barge should be cleaned, and straw bags should be paved on the walkway to prevent slipping
