Introduction: Manual hydraulic scissor lift table is a kind of equipment used to lift heavy objects or work pieces, which uses a hydraulic system as a power source. This lifting table adopts scissor structure design, usually composed of a set of transverse and longitudinal scissor arms, which are able to expand and retract each other during the lifting process, so as to achieve a smooth lifting operation.
Chapter 1 : The working principle of manual hydraulic scissor lift table
1.1 Hydraulic system
The hydraulic system is the source of power for manual hydraulic scissor lift tables. It is based on the Pascal principle, which utilizes the transfer pressure of a liquid within a closed system to achieve force transmission and power conversion.
* Hand pump or hand-operated lever: The hydraulic system usually includes a hand pump or hand-operated lever. When the operator maneuvers the pump or lever, it causes hydraulic fluid to flow through the system.
*Hydraulic Tank: A hydraulic system contains hydraulic fluid, usually in a specialized hydraulic tank. Hydraulic oil is the medium for transmitting pressure, which is extracted, compressed, and transported by the action of the pump or rod.
* Hydraulic oil piping: hydraulic oil is transmitted through the piping, connecting the pump and the hydraulic cylinder.
*Hydraulic cylinder: The hydraulic cylinder is the actuator of the hydraulic system. When hydraulic fluid enters the hydraulic cylinder, it exerts pressure on the piston, which causes the cylinder to extend or contract. The piston of the hydraulic cylinder is connected to the scissor structure so that the scissor structure is under the action of the hydraulic cylinder to lift.
1.2 Scissor structure
The hydraulic scissor lift table adopts a scissor structure, which consists of horizontal and vertical scissor arms. A platform is installed on the top of the lifting table on which heavy objects or workpieces can be placed.
* Horizontal scissor arms: Horizontal scissor arms are horizontal frames connecting vertical columns on both sides. They are connected together by hinges to form a stable parallel structure.
*Longitudinal Scissor Arm: The longitudinal scissor arm is the vertical strut that connects the platform to the transverse scissor arm. They are connected to the bottom of the transverse scissor arms by hinges and at the same time to the bottom of the platform.
*Lifting process: When the operator increases the flow of hydraulic fluid using a hand pump or manual lever, the pressure inside the hydraulic cylinder increases. This causes the piston of the hydraulic cylinder to extend upwards while pushing the upper connection of the longitudinal scissor arm upwards. Through the hinge connection of the transverse scissor arm, the transverse scissor arm also begins to unfold. In this way, the entire scissor structure stretches, thus raising the platform height.
*Descending process: If the lifting platform is to be lowered, the pressure in the hydraulic cylinder can be reduced by decreasing the flow of hydraulic fluid. This causes the piston of the hydraulic cylinder to contract and the scissor structure to refold, thus lowering the platform height.
Chapter 2: Design and selection of manual hydraulic scissor lift table
2.1 Platform size: The platform is the working area on top of the lift table, and the size can be chosen according to the need, from a small platform suitable for personal use to a large platform suitable for pallet or multiple worker operation.
2.2 Lifting Height: The maximum and minimum height of a lift table is determined by the workplace and usage requirements. Certain locations may require a large lift height, while others may only require a relatively small change in height
2.3 Scissor Arm Size: The length and width of the scissor arms will also affect the size of the lift table. Longer scissor arms usually mean a greater lifting rage.
2.4 Load capacity: Select the appropriate load capacity based on the weight of the object or work piece to be lifted. Ensure that the carrying capacity of the lift table is greater than or equal to the required load weight.
2.5 Working environment: Special working environments, such as wet, hot, or corrosive environments, may require a more durable lift table.
Chapter 3: Features of manual hydraulic scissor lift table
3.1 Energy saving and environmental protection: manual hydraulic scissor lift table does not require an electricity supply, using a manual pump or operating rod as a power source. Compared with electric lift tables, it does not consume electricity, reducing energy consumption and favoring energy saving and environmental protection.
3.2 Flexible and convenient: Manual operation makes the control and adjustment of the lift table very simple, without the need for complex electrical connections and control systems. This makes it still flexible to use in places where there is no power supply or electric equipment is inconvenient.
3.3 Safe and stable: the manual hydraulic scissor lift table adopts a scissor structure with solid support capacity. The hydraulic system provides a smooth lifting and lowering process, avoiding sudden vibration or tilting, and ensuring safety during the working process.
3.4 RELIABLE AND DURABLE: This type of lift table has a simple design with relatively few components, resulting in a low failure rate. It is manufactured from high-quality materials for good durability and long life.
3.5 Easy maintenance: Because there are no electric parts, maintaining the manual hydraulic scissor lift table is relatively simple. Regular inspection and maintenance of the hydraulic system to keep the hydraulic oil clean and sufficient is usually enough to ensure its normal operation.
