Aerial work platform efficiency and safety co-exist, lifts and other aerial work machinery and equipment are not maintained on time, not by professional engineers to regularly check the personal safety accidents will occur!
1. Hydraulic oil is not replaced on time will deteriorate, viscosity becomes low, the hydraulic pump and oil cylinder have greater harm, will accelerate the aging of the cylinder piston seals, accelerate the sealing ring wear, the initial cylinder internal leakage, the platform will automatically fall, when serious, the sealing ring will be suddenly ruptured, the platform will be a rapid decline, easy to cause casualties.
2. machine corrosion, if the machine corrosion and not dealt with in time, it will make its oxidation intensify, the toughness, strength and hardness of the steel drop, seriously affecting the safety of people.
3. motherboard cracking, weld cracking, motherboard bear the main weight of the machine, motherboard maintenance has become our main maintenance object, motherboard and motherboard weld between the motherboard is also our main inspection object, become our top priority, if the machine mechanical failure, the machine will be directly dumped, will be the equipment operator will cause 2 injuries, but also cause ground personnel or equipment damage.
4. Abnormal wear and tear of the control line will cause a short circuit or disconnection of the line, easy to burn electrical components, easy to cause a fire, the consequences are more serious, easy to make the control switch malfunction or out of control, easy to cause injuries to the operator and other personnel on the ground and damage to the equipment.
5. Tyres and wheels, tyres and wheels are the fulcrum to maintain the balance of the entire body, wheels cracked or broken, will lead to a loss of balance of the body, due to rupture of the wheel and the occurrence of safety accidents in the entire industry are high .........
In order to make our equipment "safe, efficient and standardised", I would like to make the following suggestions and plans:
1. Pre-start check: Require your qualified operators who can operate the equipment to carefully check the normal operation of the equipment's functions every day or before use or every time before replacing the operator.
2. Safety check: every 3 months, need to systematically check the whole machine; every 12 months to do a major maintenance.
3. Regularly clean the equipment and keep it at all times.
4. Operators must be trained and equipped with full body safety belt and safety helmet to ensure safety.
5. Aerial working platforms must be inspected regularly by professional engineers to ensure the quality of repairs and improve safety.
6. It is forbidden to use the equipment without doing maintenance.
Emergency stop is a necessary safety protection device for mobile aerial working platform, but now many unscrupulous manufacturers have omitted the emergency stop protection device, some manufacturers have an emergency stop button, but there is no control of the total power supply of the contactor, the emergency stop button can only control the motor power supply, when the main contacts of the contactor controlling the power supply of the motor stick, the emergency stop button does not go to the role of the power supply can not be cut off, or not be able to control the aerial working platform. The second thing is the stability of the machine.
Secondly, the stability of the machine, the stability of imported brands of lifts to do a better job, pay more attention to personal safety, the selection of steel, component processing and installation of precision is an important factor affecting the stability of the mobile lifting platform.
