In accordance with the manufacturer product instructions normal operation and maintenance There should be no unreasonable risk when maintenance. 3.1.2 three car dumper system used by the component shall comply with the national standards, industry standards, granted in accordance with prescribed procedures Quasi products manufacturing drawings and technical documents. 3.2 Security guards 3.2.1 dump system should be set after lifting the state of repair of mechanical locking devices, rollover Tipper dump transport system should be set up state Locking means. Locking device should be able to secure locking. 3.2.2 Dump system should ensure that the car does not appear automatically lifting phenomenon in the process of moving. 3.3 Lifting and fall 3.3.1 Dump system should enable the car steady rise, fall or stop at any position, there should be ran, collision and wiring. 3.3.2 at 10% overload condition, give rise to 20 °, the residence 5min, from the lower compartment of not more than 1.5 °. 3.3.3 Dump system should enable accurate return after lifting the car. 3.4 Hydraulic System 3.4.1 Hydraulic dump system pressure safety devices (pressure limiting device) should be installed. 3.4.2 hydraulic dump system 1.5 times (the rated working pressure ≤15MPa) or 1.25 times (the rated working pressure > 15MPa) rated operating Under pressure to make, is not allowed within 3min oil leakage, cracking, swelling and partial disengagement joints and so on. 3.4.3 Dump hydraulic system piping should be reasonable layout, stable fixation, away from hot surfaces, moving parts, exhaust and electrical equipment, there should be no infiltration Drain, loose, loss and interference phenomena. 3.4.4 When necessary, should be high-pressure tubing hydraulic dump system piping protection, to ensure that when the pipeline rupture, without splashing into the body. 3.5 operating mechanism Operating mechanism and other components should not have interference, measures should be taken to prevent accidental start-control mechanism. The control mechanism should be flexible, accurate Accurate, reliable, and should not be displaced due to vibration. Determining safety requirements and measures 4 4.1 General Requirements Dump system carrying dangerous does not occur during the test according to the manufacturer product instructions normal operation and maintenance, it is determined The project qualified. 4.2 Security guards 4.2.1 Visually inspect the locking device is qualified. 4.2.2 dump truck driving at full load, in the three and three of the following roads at least 1h, observe whether the carriage to automatically lift L phenomenon. 4.3 Lifting and fall 4.3.1 to 3.3.1, dump truck without a load, stopping on a flat, hard surface of the ground, steering system dump, visually check for eligibility. 4.3.2 dump truck at 10% overload state, stopping on a flat, hard ground surface, uniform load, mounted on the side of the car dump direction fence Inclinometer, then the coaches give rise to 20 °, the residence 5min, read and record the starting and ending point of view angle instrument, calculate the difference. Press dumping direction, Each repeated three times, and three times the difference between the average value of the compartment from the lower amount. 4.3.3 Dump visual system enables car lifting the return after the accuracy of eligibility. 4.4 Hydraulic System 4.4.1 to 3.4.1, a visual inspection pressure safety devices (pressure limiting device) is set. 4.4.2 hydraulic dump system pressure rises to 1.5 times (the rated working pressure ≤15MPa) or 1.25 times (the rated working pressure After > 15MPa) rated working pressure, keeping 3min, to observe whether there is oil leakage, cracking, swelling and partial disengagement joints and so on. 4.4.3 to 3.4.3, a visual inspection is qualified. 4.4.4 to 3.4.4, a visual inspection is qualified. 4.5 operating mechanism Dump system operated steering mechanism, visually check for eligibility.5 Use Information5.1 Dump system controls, graphic indicators and telltales signs shall comply with GB/T 19122 of. 5.2 Dump sides should type car dumper system for safety signs residual risks, safety signs, composition, color and size should be consistent GB 10396 of the regulations. Dump near 5.3 system is easy to see the position of the operating mechanism should be set up operation identifying, labeling should provide clear information on the operating mechanism, and with the background Clear color. 5.4 tipper manual, Tipper system should be given the main technical and performance parameters. 5.5 Tipper operating instructions, shall be given to use dump system controls and locking devices, and highlighted. --- Dump process, the cargo box dump direction is prohibited to stand on; after the lift cylinder from the top, should firmly support the locking device before below operation; --- Strictly prohibited in the slope of more than 5% of the cross-slope lift cargo containers, to prevent accidents caused by rollover or skid; --- When the lifting operation, the engine speed should be kept uniform and stable, not Meng throttle; --- In the transport position, each locking device should be reliable locking. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB 24939-2010_English be delivered?Answer: Upon your order, we will start to translate GB 24939-2010_English as soon as possible, and keep you informed of the progress.
