Your complete resource on tracked boom lifts, tracked cherry pickers, and tracked access platforms
A spiderlift, also known as a tracked boom lift, tracked cherry picker, or tracked access platform, is a specialised type of mobile elevated work platform (MEWP) designed for working at height in challenging environments. They are characterised by their tracked chassis, similar to a tank, and their ability to become very compact for transport and access.
This is the defining feature of a spiderlift. The tracks distribute the machine's weight over a larger area, resulting in low ground pressure. This design provides exceptional stability and traction on various terrains, including soft ground, rough terrain, and slopes. Tracks also allow for easy movement over gravel and mud. Some models have hydraulically adjustable track width for narrowing to fit through tight spaces or widening for better stability.
When stowed, many spiderlifts are notably compact, often less than one metre wide and two metres high, allowing them to fit through standard doorways, narrow gates, and tight internal corridors. Even larger machines with working heights over 30 metres can often pass through double doors. This makes them highly versatile for both indoor and outdoor work, especially in areas with restricted access.
Spiderlifts are equipped with four extendable stabiliser legs, or outriggers, which can be individually adjusted to level the platform on uneven surfaces. These outriggers provide a wide and secure base, enhancing stability, particularly when the boom is extended or operating on inclines. They are supplied with outrigger pads to evenly distribute weight and reduce the risk of sinking on softer ground. Some designs, like the cranked or bent stabiliser leg, offer increased ground clearance during setup.
The working platform or basket is attached to either an articulated or telescopic boom lift, providing both vertical and horizontal reach.
Working heights typically range from approximately 11 metres to over 52 metres. They also offer significant horizontal outreach and some models also feature negative reach capabilities, allowing them to extend below ground level.
Generally, the safe working load (SWL) for spiderlifts ranges from 200kg to 300kg, typically accommodating one or two operators with tools. However, some advanced models can achieve a 400kg lifting capacity. It is important to note that maximum lifting capacity can sometimes depend on the horizontal outreach.
Spiderlifts offer diverse power sources:
Modern spiderlifts include essential safety features such as load sensors, tilt alarms, emergency lowering systems, and automatic self-stabilising systems. They also have proportional controls for smooth operation and harness points for operator safety.
Spiderlifts were introduced around 1998 as "game-changers" in the access equipment industry, addressing the need for versatile solutions in difficult environments.
Spiderlifts are hired across a wide range of industries in the UK due to their versatility:

When hiring a spiderlift, consider factors like working height, outreach, access constraints, weight limits, basket capacity, and power options. Many hire companies offer advice, site surveys, and flexible hire terms. New technologies like AI assistants and carbon offset schemes are also being introduced to improve the hiring experience.
