The working principle of the type lifting platform is to use a motor to drive the worm to move the screw up and down, and to equip the lifting cage
function with a device that can realize online control. The most important features are self-locking performance and synchronization. If you are interested, please understand it with the editor! Mechanical lifting platform is composed of worm, box, bearing, screw and other parts. The boarding bridge is used for bridge equipment between forklifts and trucks to facilitate loading and unloading of goods. Maximum dynamic load: 6T, maximum static load: 6T, maximum width: 2M, maximum length: 4M. There are many categories, generally divided into mobile docking bridges and fixed docking bridges. Conventional: solid tires with a length of 11M and a width of 2.1M. Its working principle is: the motor or manual drive worm rotates, the worm drives the worm gear to rotate, the internal thread of the worm wheel is processed, and the drive screw moves up and down. Due to the effect of the internal worm and the lead screw, the thrust is affected. The lifting platform rotates by driving. Functional characteristics By driving the worm to rotate, it can realize up and down movement, push and pull or construction lift
. The hydraulic lifting platform is driven by steel wire ropes and is mostly used to transport goods. It is composed of tower, hanging basket, hoist, etc. The tower is generally a truss structure, which is pulled by cables to keep it upright. The hanging basket is welded with section steel and is a container for loading goods. The hoist is fixed on the ground, the wire rope is connected to the gondola through the pulley on the top of the tower, and the gondola is pulled to run up and down, and the operator controls it on the ground. 1. The self-locking performance of ordinary screw hydraulic push rods and screw pumps. Due to the low comprehensive transmission efficiency, most of them have absolute dynamic load self-locking function, which improves the safety of equipment operation. Ball screw hydraulic push rods and screw pumps are not self-locking. 2. The comprehensive positioning accuracy of the servo hydraulic cylinder can reach 0,1mm, and the positioning accuracy of the servo hydraulic cylinder can reach /3. The encoder can be precisely controlled and controlled by the frequency converter or controller to realize the closed-loop precise positioning. In the case of low accuracy requirements, it can be equipped with online control. (4) Synchronous single motor drives multiple push rods through mechanical connection at the same time to achieve synchronous lifting cage and absolute synchronization; 5. Drive system: DC motor, single AC motor , Three-phase AC motor, no air/hydraulic source; 6. Overload protection can be equipped with a safety clutch to prevent overload, and an overload pressure sensor can also be equipped to prevent overload; 7. High load push and pull up to 300 tons; 8. Other simple maintenance, low noise , Can work in the harsh environment of high/low temperature, corrosion resistance/explosion-proof; the most important features are: self-locking performance, synchronization, precise positioning, speed control, thrust control. The type lifting platform is driven to rotate by the type lifting platform is more about the machine than . The hydraulic docking bridge is a special auxiliary equipment for fast loading and unloading of goods. Its height adjustment function enables a bridge between the truck and the cargo platform of the warehouse. The forklift and other handling vehicles can directly drive into the truck for bulk loading and unloading through it. Called the loading and unloading platform. Introducing the spiral lifting platform, I believe that after careful reading, friends have learned that the spiral lifting cage platform can work in the harsh environment of anti-corrosion/explosion-proof, and it can also accurately position and control the thrust.
