Mobile Scissor Lift Equipment

The core components of a self-propelled scissor lift include structural, hydraulic, electrical control, drive, power, and safety systems. The price difference between components from different brands is significant, which explains why products with similar appearance and specifications can have a price difference of up to $3000. Below, we will introduce the most critical components of a self-propelled scissor lift.
1. The scissor arm structure, as the core load-bearing and lifting frame of the entire machine, is composed of high-strength manganese steel/alloy steel rectangular tubes, pins, and hinges, determining the lifting height, load capacity, and stability of the lift. Domestic scissor lifts commonly use Q345/Q235 high-strength steel from Jisteel and Ansteel.
2. The hydraulic system includes a power unit, cylinders, valve blocks, and seals. Its main function is to provide lifting and driving power for the lift, achieving smooth lifting, precise speed control, and safety locking through the pump station, cylinders, and valve blocks. Mainstream brands for power units include Eaton (USA), Danfoss (Denmark), Brevini (Italy), and domestic brands such as Lisheng (Sino-German joint venture) and Suzhou Haipu.
Common brands for valve blocks/solenoid valves include Hydraforce (USA), SANT (Italy), and Winner (Taiwan).
3. The electrical control system mainly includes controllers, electrical components, and control panels. They control the machine's movement, lifting, steering, and safety protection. The main electrical components include the main controller, contactors, limit switches, and control panel.
Mainstream brands: Schneider (France), ABB (Germany), Omron (Japan), and domestic brands such as Chint and Delixi.
4. The drive system includes drive wheels, drive motors, and brakes. There are two drive system options: the first is motor-driven, and the second is hydraulic wheel-driven. It enables self-propelled functionality, with the drive wheels providing traction, and the motor and brakes controlling speed and stopping, ensuring driving safety.
Mainstream brands for drive motors/drive wheels include: White (USA), Danfoss (Denmark), and Brevini (Italy).
Brakes: White (USA) multi-disc wet brakes, Bosch Rexroth (Germany) hydraulic brakes, etc. 5. The battery and charging system provide the power source for the electric self-propelled scissor lift, ensuring continuous operation and charging efficiency. Currently, Contemporary Amperex Technology Co., Limited (CATL) is the largest supplier of batteries in China.
