SJY0.5-14

This is a mobile scissor lift (also known as a scissor lift platform or hydraulic lift), which is a type of aerial work platform. Its core structure is a scissor - type lifting arm, and the platform is driven to rise and fall vertically by the expansion and contraction of the arm frame through a hydraulic system. Here is a detailed introduction:

1. Basic Structure and Principle

•Structure: It consists of a base (with wheels), a scissor - type arm frame (multi - section high - strength metal arms), a working platform (with guardrails), and a hydraulic system. The equipment in the picture is traction - type (with a towing hook), and there are support legs at the bottom, which can be expanded to stabilize the fuselage during operation.

•Power: Most of them are driven by electric hydraulics (there are also diesel - powered models). The scissor arms are pushed by oil cylinders to expand and contract to realize the lifting of the platform; some models support "full - stroke walking", that is, they can move a short distance during the lifting process.

2. Core Parameters and Functions

•Lifting Height: Conventional models cover 4–20 meters (such as 6 meters, 10 meters, 16 meters), and different heights meet the needs of high - altitude installation and maintenance.

•Load - bearing Capacity: It ranges from 200–2000 kg, supports 1–3 people to work at the same time, and the platform area is wide (some can be extended), suitable for carrying tools and materials.

•Safety Design: It is equipped with tilt protection, pothole protection (to prevent accidental operation from falling into potholes), an emergency descent valve (to manually release pressure to lower the platform when power is off), and a safety maintenance support rod (to fix the arm frame during maintenance); some high - end models have a built - in electronic weighing system (to prevent overloading) and fault diagnosis function.

3. Application Scenarios

It is widely used in indoor and outdoor aerial operations:

•Factories/Warehouses: Equipment installation, shelf replenishment, lamp maintenance;

•Construction/Renovation: Indoor ceiling construction, exterior wall painting (low - height models);

•Transportation Hubs: Sign installation in airports/stations, ceiling maintenance;

•Others: Sports venues, gas stations, elevated pipeline maintenance, etc.

4. Advantages and Features

•Strong Stability: The scissor structure provides high support stiffness, and the platform has little shaking when lifting;

•Easy to Operate: Double control up and down (both the platform and the base can be operated), one - key lifting, no professional training required;

•Environmentally Friendly and Energy - saving: The electric model has zero emissions and low noise, suitable for indoor use;

•Flexible Movement: The traction - type can be dragged and transferred by forklifts/trucks, and the self - propelled type (high - end type) can drive short distances independently.
