History of human use of hydraulic scissor lift.
The need for vertical transportation is as old as human civilization. The earliest lifts used human, animal, and hydraulic power to lift weight. Lifting devices have relied on these basic power modes until the industrial revolution. In ancient Greece, Archimedes developed an improved lifting device operated with ropes and pulleys, which used winches and levers to wind the lifting ropes on the bobbins.
In 80 AD, gladiators and wild animals took the primitive lift to reach the height of the arena in the Roman Coliseum. The records of the Middle Ages include countless people who lifted the lifting device and patterns that provided supplies to isolated locations. The most famous of these is the lift of the St. Baram Monastery in Greece. The monastery is located on the top of a mountain about 61 meters above the ground. The hoist uses baskets or cargo nets to transport people and goods up and down. In 1203, the lift of a monastery on the coast of France was installed using a huge treadmill, powered by a donkey, and by winding a rope around a huge pillar, the load was lifted.
In the 18th century, mechanical power began to be used in the development of lifts.
In 1743, Louis XV of France authorized the installation of personnel lifts using counterweights in a private palace in Versailles. In 1833, a system using reciprocating rods lifted miners in the Harz Mountains of Germany.
In 1835, a belt-drawn hoist called a "winch machine" was installed in a factory in England. In 1846, the first industrial hydraulic lift appeared. Then other powered lifting devices appeared soon after.
In 1854, American mechanic Otis invented a ratchet mechanism, which was displayed at the New York Trade Fair. The safety lift.
In 1889, when the Eiffel Tower was built, a steam-powered lift was installed, which was later switched to an lift.
In 1892, the lifting equipment of Mount Astilero in Chile was completed. Until now, 15 lifts still use machinery and equipment from more than 110 years ago.
In 1958, the world’s first scissor lift came out, with hydraulic system,it became the most convenient way for aerial work. And with years development, 4 varieties have been derived from this series, mobile scissor lift, self-propelled scissor lift, scissor lift table and fixed scissor lift.
Mobile hydraulic scissor lift
Brief introduction of mobile sissor lift:
The mobile scissor lift is a special equipment high-altitude operations with a wide range of uses. Its scissor structure machinery makes the lifting platform more stable. The equipment adopts a high-strength manganese steel structure to increase the quality of the equipment. The large working platform and the ability of load makes high-altitude operations large and many people work at same time. It makes high-altitude operations more efficient and safe! 12m/14m/16m/18m and 20m different platform height to choose from. If you need special load and height, you can order, you can also choose voltage, such as 380v, 220v, battery and fuel engine as the lifting power, special occasions can also choose explosion-proof electrical appliances.
Application of mobile hydraulic scissor lift:
Applicable conditions: construction sites, factories, warehouses, grain depots, stations, hotels, airports, gas stations, stadiums, overhead pipelines and other high-altitude equipment installation, maintenance, cleaning, etc. It is also used for maintenance of lifting equipment and maintenance of field power facilities. Maintenance of steel frame structure workshop, etc. Let me tell you about my own experience. In the past, there was no such equipment in our house. Our family had a tall persimmon tree. Every time I went up to pick persimmons, my father had to climb up on a bamboo ladder, and someone needed someone underneath. Leaning on a ladder is both unsafe and wasteful of manpower. Since my family bought this machine, a weak woman can rise to a high level to pick persimmons. It is safe and saves manpower. Moreover, this machine has a long service life and is convenient for storage. It won’t take up much space if you put it in the corner.
Because I have personally experienced our products and know how much convenience they bring to me, I believe in the quality of my products, so I sincerely recommend this products to you.

If these faults of the electric scissor lift table are not dealt with, the electric scissor lift table will eventually be paralyzed. Or more serious consequences. The following questions are details that most operating users often overlook:
Common problems of hydraulic scissor lift table:
2.3.1. The button is out of order. The lifting, lowering, and suspending operations of the entire electric scissor lift table are all controlled by the button. If there are occasional key failures during operation, you should pay attention to this phenomenon. This phenomenon may be a short circuit of the electric hydraulic platform car circuit or the imminent failure of the electrical system. At this time, you must check carefully in time to avoid affecting the operation of the electric scissor lift table in the future.
2.3.2. The electro-scissor lift table cannot be lowered to the natural height and causes a malfunction. The reason is:
①Deformation of the main frame of the electric scissor lift table;
②Too much hydraulic oil is injected into the electric scissor lift table;
③There are sundries between the scissor levers of the electric scissor lift table.
2.3.3. The motor of the electric hydraulic platform car is noisy, and occasionally there will be heat or odor of the motor. The reasons for such problems are:
① The electric hydraulic platform vehicle is overloaded. If there is an overload problem, uninstall it in time.
②The voltage of the electric hydraulic platform is unstable. Check whether there is any problem with the circuit.
③If the motor is not well sealed or the coil is burned out, the seal should be tight or the coil should be replaced in time.
Timely correction of minor problems can avoid major failures and enable the electric scissor lift table to operate stably for a long time. In view of the hidden troubles of electric hydraulic platform vehicles, timely detection and elimination of problems can reduce the occurrence of many failures. Finding hidden dangers in time and shutting down to eliminate them is the key. We usually need to take more preventive measures.
