Scissor Type Aerial Work Platform

Product Introduction

Fully self-propelled scissor type aerial work platform are a type of safe and efficient equipment for high-altitude operations, covering various types such as scissor type, curved arm type, and straight arm type. They are widely used in exterior wall painting and steel structure installation in construction, equipment maintenance and high-level shelf maintenance in industrial plants, streetlight repair and green pruning in municipal engineering, as well as facility installation and cleaning maintenance in public places such as shopping malls and airports. Compared to traditional scaffolding and ladders, it significantly reduces the risk of falling from heights and improves work efficiency due to its stable working platform and flexible mobility, making it the preferred tool for high-altitude operations in various industries.

1. Stable structure and high safety factor

Adopting a symmetrical articulated scissor arm structure, paired with high-strength manganese steel material, the center of gravity moves vertically during the lifting process, with minimal shaking amplitude; Equipped with multiple safety devices such as overload protection, anti rollover, and emergency descent valve, it can effectively avoid the risks of high-altitude operations.

2. Dual power mode, suitable for all scenarios

There are two types of power: electric and diesel. The electric model has zero emissions and low noise, suitable for indoor enclosed spaces such as shopping malls, factories, and office buildings; The diesel version has strong power and, when paired with off-road tires, can meet the needs of non paved road operations such as outdoor construction sites and parks.

3. High load-bearing capacity, improving operational efficiency

The rated load can reach 300-1000kg, and it can carry 2-4 workers, tools, and building materials at the same time, reducing the number of back and forth handling between the ground and high altitude, greatly shortening the construction period, especially suitable for long-term fixed-point operations.

4. Easy operation and maintenance, outstanding cost-effectiveness

Using a button or handle style operating interface, ordinary workers can start working after 1-2 hours of training; The mechanical structure is simple, the failure rate of core components is low, and daily maintenance only requires inspection of vulnerable parts such as oil, batteries, and tires. The procurement and usage costs are much lower than those of curved arm and straight arm platforms.

5. Multiple specifications to choose from, covering the needs of the entire industry

From mini models with a width of ≤ 0.8m and elevator access, to large models with a working height of 30m, suitable for different scenarios; Widely used in construction decoration, industrial operation and maintenance, municipal engineering, commercial services and other fields, it is one of the most versatile high-altitude work equipment.

Product working principle

1. Principle of Power Conversion

The power source of the equipment (electric motor or diesel engine) drives the hydraulic pump to operate, converting electrical/mechanical energy into hydraulic energy, generating high-pressure oil, and providing power support for the entire lifting system. This is the energy foundation for the operation of the equipment.

2. Principle of articulated motion of scissor arm lever

High pressure oil is delivered to the hydraulic cylinder, and when the cylinder piston extends and retracts, it pushes the cross hinged scissor arm to rotate around the hinge point. When the scissor arm is extended, it drives the work platform to rise vertically; When the scissor arm folds, the platform descends smoothly and achieves lifting and lowering movements under high loads through the leverage effect.

3. Principle of precise control of lifting speed

The hydraulic system is equipped with control valves such as one-way throttle valves and relief valves. By adjusting the flow rate and pressure of the oil, the expansion and contraction speed of the oil cylinder piston is precisely controlled, thereby achieving adjustable and controllable platform lifting speed, avoiding impact or jerking during the lifting process.

4. Principle of safety protection linkage control

The safety devices of the equipment (overload sensors, tilt sensors, guardrail threshold switches, etc.) are linked with the hydraulic system and control system. When there are abnormal situations such as overloading, excessive platform tilt, and unclosed guardrail doors, the sensor triggers a signal, and the control system immediately cuts off the power of the hydraulic pump or locks the oil cylinder, forcing the lifting action to stop and ensuring the safety of the operation.

5. Interlocking principle between walking and homework

The self-propelled scissor platform is equipped with a walking lifting interlock mechanism. When the work platform is in a raised state, the interlock device will automatically lock the walking drive system to prevent accidental movement of the equipment during high-altitude operations; Only when the platform is lowered to the lowest position can the walking function be unlocked to avoid the risk of overturning.

Product Application

1. Construction scene

Used for insulation of exterior walls, installation of glass curtain walls, welding of steel structures, as well as high-altitude installation of indoor ceilings, lighting fixtures, and central air conditioning pipelines.

2. Industrial operation and maintenance scenarios

Adapt to the maintenance of large-scale production equipment in factories, workshop crane maintenance, as well as the installation, storage, and maintenance of high-level shelves in warehousing and logistics centers.

3. Municipal engineering scenarios

Undertake the installation and commissioning of urban street lights and traffic signals, disassembly and assembly of outdoor billboards, as well as pruning and shaping of tall trees in urban greening.

4. Commercial venue scene

Satisfy the decoration and layout of the mall atrium, cleaning of the glass dome, maintenance of escalators, as well as the installation of signage and maintenance of ceilings in airport terminals and high-speed railway stations.

5. Emergency rescue scenarios

Applied to personnel evacuation in high-rise building fires, high-altitude rescue at accident sites, and high-altitude operation support in emergency situations such as road collapses and power repairs.

Fully self-propelled scissor type aerial work platform

1. Q: What key parts need to be checked before homework?

A: It is necessary to check the stability of the chassis, whether the leg deployment is in place, and whether the scissor arm is deformed or damaged. At the same time, it is necessary to confirm that the hydraulic oil/battery power is sufficient, and safety devices such as the walking lifting interlock and overload protection are triggered normally.

2. Q: Does the rated load include the weight of operators and tools?

A: Yes, it is. The rated load is the total weight (including personnel, tools, and materials) that the platform is allowed to carry. Overloading operations are strictly prohibited, otherwise it may trigger the system lock and damage the scissor arm structure.

3. Q: Under what ground conditions can work be carried out? What is the maximum allowable slope?

Work on a flat and hard surface, avoiding muddy, soft or cluttered areas; Indoor models allow a slope of ≤ 3 °, while outdoor off-road models allow a slope of ≤ 5 °. Exceeding the slope will trigger a tilt alarm and cut off power.

4. Q: What is the daily maintenance cycle and focus?

Check tire wear and hydraulic pipeline sealing every week; Replace the hydraulic oil filter element (diesel version) and test the battery life (electric version) every month; Quarterly lubrication of the scissor arm hinge point ensures easy overall maintenance and low failure rate.

5. Q: What should I do if there is a sudden power outage during high-altitude operations and the platform cannot descend?

The equipment is equipped with an emergency descent device as standard. The electric version can use a backup power supply, while the diesel version can release pressure through a manual hydraulic valve. By slowly operating the handle according to the operation manual, the platform can be smoothly lowered to the ground, and the entire process is safe and controllable.
