What is a towed spider lift?

You won't feel unfamiliar when hearing the term spider lift, but you may need to think twice about a towed spider lift. Simply put, a towed spider lift is an aerial work platform that moves by external traction without a built-in travel drive, and is also equipped with a crawler chassis and adjustable hydraulic outriggers. When the outriggers are deployed, they look like a spider's legs. It can perform aerial operations in narrow spaces, complex terrains and fragile ground areas, with precise, safe and stable operation, and is also a major main equipment for aerial work.

一、Core Structure

Towed design: Without a built-in drive motor, it needs to be towed by a forklift or a small trailer during transfer. After retracting the boom and outriggers, it has a very compact shape, can easily enter narrow spaces such as elevators and corridors for operation, and the transportation cost is relatively low.

Spider-type outriggers: Standard equipped with 4 independent hydraulic outriggers with multi-angle adjustment, which can automatically level on steps, slopes and soft ground, ensuring the whole machine is as stable as a rock during operation.

Rubber crawler chassis design: With a large ground contact area and low ground pressure, it will not scratch vulnerable surfaces such as marble, is suitable for both indoor and outdoor use, and can also turn slightly on the spot.

Folding telescopic boom: Adopting a folding plus telescopic structure, the working height is generally about 10-22 meters, and it can flexibly cross obstacles. The boom features stepless speed regulation, and is matched with a wired or wireless remote control for precise operation.

Platform load capacity: Generally about 200kg, it can carry 1-2 workers plus tools, and can realize 360° rotation and fine angle adjustment.

Powered by electricity and lithium battery: Achieving zero emission and low noise, it is equipped with an overload protection system, an emergency descent system and an anti-rollover system to ensure the safety of aerial work.

二、Advantages to Solve Operation Pain Points Directly

The towed spider lift has a small size after retraction and can enter narrow spaces that ordinary aerial work platforms cannot access, such as basements and shopping mall atriums.

With the combined design of crawlers and outriggers, its ground pressure is far lower than that of traditional aerial work platforms, so it will not cause indentations or damage in places with strict ground requirements such as museums, hotel lobbies and libraries.

The boom moves stably and the platform can be fine-tuned in angle, making the towed spider lift suitable for high-precision work such as lamp replacement and cultural relic building renovation.

Its structure is simpler than that of a self-propelled spider lift, with very low purchase and daily maintenance costs. No large trailer is needed for transfer, resulting in less investment in human and material resources.

Conclusion

When purchasing a towed spider lift, it is necessary to clarify the core parameters, such as working height, horizontal outreach distance and platform load capacity. For daily maintenance, regularly check the hydraulic oil, crawler wear, seals on the outriggers, etc. Regular inspection can extend the service life of the equipment.
