The platform of aerial platforms is currently a widely used aerial work platform equipment. Its safety issues are directly related to the safety of personnel working at height. At present, most domestic mobile aerial work platform manufacturers simplify product design in order to reduce costs, which greatly reduces the safety factor of mobile lift platforms.
The bushings of the previous scissor arm for aerial work platforms were all made of seamless steel tubes. The wear resistance of the bushings was poor and their service life was short, which seriously affected the safety performance and service life of the lifts. The use of wear-resistant mobile lift table, the life of the straight arm sleeve doubled, but due to the high price of wear-resistant sleeves, most lift table manufacturers currently use wear-resistant sleeves on large tonnage lift tables.
The axle pin of the aerial work platform is mostly made of round steel. If it is not heat-treated, the hardness of the pin cannot meet the requirements and the wear resistance and strength are poor. The use of a mobile lift table that has not been subjected to a heat-treatment shaft pin results in a short life of the pin, and if the strength of the pin varies from the design requirement, the pin is easily broken, which seriously affects the safe operation of the mobile lift table.
When the lifting table equipment fails and cannot be stopped, the emergency shutdown device is used. If there is no emergency stop, when the limit switch malfunctions or the contactor main contact sticks and cannot be disconnected, the lifting platform cannot rise and it cannot stop. The consequences are serious and directly threaten the safety of workers on the work platform of mobile aerial work platforms.
Emergency stop is an essential safety protection device for mobile aerial work platforms, but now many unscrupulous manufacturers have saved emergency stop protection devices. Some manufacturers have emergency stop buttons, but they do not have contactors that control the main power supply. The stop button can only control the motor power supply. When the main contactor of the contactor controlling the motor power is stuck, the emergency stop button does not work at all, and the power supply cannot be turned off, or the aerial work platform cannot be controlled.
The basic material of the metal structure of the mobile lift table, the steel performance directly affects the strength and stability of the metal structure of the lift table. Now many domestic lifting platform manufacturers in order to reduce costs, purchase less than the national steel standards of non-standard steel, non-standard steel due to steel can not meet the design needs of strength, leaving the hidden danger of mobile lift platform safety performance.
The amount of yaw of the elevating platform, if the amount of yaw of the aerial work platform is too large, the stability is too bad, the accuracy of the component adding and installing work is an important factor affecting the stability and yaw amount of the mobile elevating platform, if the processing of equipment components The accuracy and installation accuracy are low, and the connections between the components are matched. This can easily reduce the stability of the lifting platform, which can easily lead to rollover of the lifting platform and the safety of crisis workers.
