What Is a Tracked Spider Lift?
A tracked spider lift, also known as a spider-type aerial work platform, gets its name from its outriggers, which resemble spider legs. Its core function is to safely transport operators and tools to working surfaces 10-30 meters above the ground in confined or complex terrain.
The machine features a modular design; when folded, its width is only 0.8 meters, and its height is 2.2 meters, allowing it to easily pass through standard doors and elevators.
The core structure consists of four parts:
- Rubber track chassis: Ground pressure is only 0.03MPa, less than the pressure of a standing human body, so it won’t damage lawns or paving stones.
- Independent hydraulic outriggers: Four outriggers can be extended and retracted independently, automatically leveling, allowing stable operation in a space of only 3㎡.
- Multi-section boom: Telescopic + articulated design, capable of bypassing obstacles and rotating 360 degrees without blind spots.
- Personnel work platform: Equipped with safety railings and an emergency stop button, with a load capacity of 200- 300 kg, accommodating 2-3 people simultaneously.

What Are the Core Functions of a Tracked Spider Lift?
- First and foremost, its most significant advantage is its ultra-narrow passage width. YG’s spider lift has a folded width of only 0.8-1.2 meters, while a standard doorway is 0.9 meters wide, allowing the spider lift to pass through easily. Many shopping malls, hotels, and exhibition halls have narrow entrances that large aerial work platforms simply cannot fit through. The spider lift, as if possessing “shrinking bones,” effortlessly squeezes through these doors.
- The tracked chassis also boasts excellent off-road performance. The rubber tracks have a large contact area with the ground, resulting in low ground pressure, allowing it to travel on soft ground, grass, and mud. The tracks provide strong traction, enabling stable travel even on slopes, with a maximum climbing ability of 25-30 degrees. The spider lift easily handles situations where wheeled equipment is prone to slipping and getting stuck.
- The four independent outriggers are a hallmark of the spider lift. Each outrigger can be independently extended, retracted, and adjusted in angle, allowing for leveling of the equipment on uneven ground. The outriggers have a large extended span, resulting in excellent operational stability. More importantly, the outriggers have a small footprint, allowing operation in many confined spaces with all four outriggers extended—something traditional aerial work platforms cannot do.
- YG’s spider lift is equipped with 360-degree continuous rotation. The work bucket can rotate freely around its center, covering a large surrounding work area without requiring equipment relocation. This is particularly useful for indoor operations or in spaces with limited space; the equipment can simply rotate to reach the next work point without moving, greatly improving efficiency.
- The folding boom design is also ingenious. The multi-section folding boom combined with the flying arm provides highly flexible operating range. It can lift upwards, extend horizontally, and work downwards. It has strong obstacle avoidance capabilities, allowing it to navigate around obstacles to reach the work point. The maximum working height ranges from 12 meters to 50 meters, and the maximum horizontal reach ranges from 6 meters to 25 meters, meeting various operational needs.
- The intelligent control system is another highlight. Control panels are located on both the work bucket and the ground, allowing operation from either side. It integrates multiple safety protection functions, including tilt protection, overload protection, height and width limit protection, and an emergency stop button. The operation is simple and intuitive; workers can become proficient after simple training.

Where Are Tracked Spider Lifts Suitable for Use?
- One of the most common applications is tree lifting in landscaping. Urban greening and tree maintenance, orchard pruning, and park landscape maintenance often involve uneven ground and obstructions from other trees. Spider lifts can easily navigate forest paths and work under trees; their flexible booms can reach all parts of the canopy, making them far more convenient than traditional lifts.
- Building construction and maintenance are also important applications. Spider lifts can be used for exterior wall construction, glass curtain wall installation, exterior wall cleaning, and exterior wall repair of high-rise buildings. They are particularly useful for repairing older buildings where limited space prevents large equipment from entering. They are also frequently used in interior decoration work, such as ceiling installation, lighting installation, and wall construction.
- The demand for municipal infrastructure maintenance is also significant. Street light repair and installation, traffic light maintenance, billboard installation and replacement, bridge inspection and repair, and tunnel maintenance are all ideal applications for spider lifts. Many municipal operations take place in narrow urban areas, where the small size and high maneuverability of spider trucks are highly advantageous.
- The interior maintenance of shopping malls, hotels, and exhibition halls is a classic application for spider trucks. These places have high ceilings and numerous lighting fixtures, air conditioning vents, and fire-fighting facilities requiring maintenance. However, entrances are often narrow, making it difficult for large equipment to enter. Spider trucks, with their ultra-narrow passage width, can easily enter these spaces, and their low pressure on the floor during indoor operations prevents damage to floor tiles. Their 360-degree rotation provides a wide coverage area.
- Spider trucks are also indispensable for the maintenance and repair of industrial facilities. They can be used for equipment inspection, pipeline installation and maintenance, and anti-corrosion coating of steel structures within factory buildings. This is especially true in chemical plants and power plants, where complex interior spaces and numerous obstacles allow the spider truck’s flexible boom to navigate around obstacles and reach the work site.
- Applications in the power and telecommunications industries are also increasing. Substation equipment maintenance, transmission line tower maintenance, and communication base station installation and maintenance all require working at height. Many substations are built on mountains with poor road conditions, which the spider truck’s tracked chassis can easily handle.
- Film and television production and event setup are also emerging application areas. Large concerts, award ceremonies, and film and television shooting sets require the construction of lighting rigs, sound rigs, and the installation and debugging of equipment. Spider trucks are small in size and lightweight, will not damage the stage floor, and their flexible booms can quickly reach various work points, making them ideal for such temporary setups.
