Hydraulic lifts add insurance to aerial construction
The analysis of dynamic safety and stability of hydraulic hoist, from the practical point of view, with reference to the method of crane design specifications, the dynamic safety and stability of hydraulic hoist was analyzed and calculated, and the theoretical formula was derived by “stability coefficient method”, and the mathematical model was established. On the basis of the original stability function, the influence of horizontal load, wind and inertia force on the stability of the structure is considered.
Hydraulic lifts are sometimes subjected to large external forces under non-working conditions. However, unlike cranes, generally the safety and stability of the machine need not be considered, considering that the crane boom is long and can be lowered to the ground or other protective measures can be taken, and even if it cannot be placed on the ground, the anti-tip stability can be improved by increasing the balance weight. However, hydraulic lifts are different. If the balance weight is too large, the boom of the hydraulic lift will tilt backwards when it is turned over, so it is necessary to check its own stability. This is to ensure that the center of gravity of the entire machine of the hydraulic lift falls within the rectangle formed by the chassis connection. In order to ensure a certain degree of safety, it is stipulated that the pressure on the same side of the tire cannot be less than 15% of the dead weight.
With the increase of actual use, the functional requirements for safety and stability of self-propelled aerial platforms are also increasing. Designers have made breakthroughs in boom amplitude jitter, boom telescopic noise, boom telescopic instability, four-wheel steering synchronization, electrical leveling, leg extension detection technology, up and down amplitude in place buffer control, rotation, etc. At present, most of the high-end equipment are equipped with anti-tip device and soft contact anti-collision device, while adopting electro-hydraulic proportional valve stepless speed change system, which further improves the safety and stability of the products.
Each hydraulic lift will complete the corresponding static and dynamic load tests before leaving the factory to ensure the safety and stability of the product under all angles and height restrictions. Also, based on the testing, the manufacturer will check the various components and systems of the product to ensure that the design features and safety are consistent with the actual product.
In fact, safety and stability is one of the basic safety features of self-propelled hydraulic lifts and a prerequisite for the proper operation of the equipment. Scissor lift platform is divided into: fixed scissor lift, mobile scissor lift, self-propelled scissor lift, vehicle-mounted scissor lift, manual traction scissor lift, and cargo-specific scissor lift. The hydraulic lifting platform, with its light appearance, can play the highest lifting capacity in a very small space. It makes single person aerial work a breeze.
Factories, hotels, buildings, shopping malls, stations, airports, stadiums, etc. The main use is the installation and maintenance of power lines, lighting appliances, overhead pipelines, aerial cleaning and other single-person work at height.
