Generally speaking, all mechanical equipment required for earthwork construction, road construction and maintenance, mobile lifting and loading and unloading operations, and comprehensive mechanized construction projects required for various construction projects are called construction machinery. Most of the construction machinery are large-scale machinery, and construction machinery may malfunction during use. If the position of the construction machinery that malfunctions is high, people need to stand on the corresponding lifting platform, and the lifting platform will lift people to the corresponding height to facilitate the maintenance of the construction machinery.

[0003] After searching, the utility model patent with Chinese patent number CN202120504636.5 discloses a lifting device for engineering machinery maintenance, including a chassis and a belt. Both sides of the top of the chassis are fixedly connected with support plates, the top of the support plate is fixedly connected with a connecting plate, and the bottom of the inner cavity of the chassis is fixedly connected with a servo motor. When in use, the lifting device is first moved to the desired position through the setting of the universal wheel, and then the electric push rod is started to push the fixed plate to contact the ground. At this time, the lifting device can be made more stable during use to avoid slipping and affecting the later use. Then the servo motor is started to drive the active pulley to rotate. Then, the belt drives the two driven pulleys and the threaded rod to rotate simultaneously, and the rotation of the two threaded rods can drive the threaded cylinder that is limited to move up and down, so as to push the placement plate and the tool box to be lifted and lowered, which can make it more convenient for users to take the maintenance tools and improve the maintenance efficiency. Since the width of the upper side of the construction machinery is smaller than the width of the base, when the placement plate is lifted to the corresponding height, there is a certain space between the placement plate and the construction machinery. When people repair the construction machinery, they need to put one foot on the placement plate and the other foot across the space to step on the mechanical equipment. There is a risk of slipping during the maintenance process.
