General Questions
What is a spider lift?
Spider lifts, also known as tracked aerial platforms or crawler booms, are compact and versatile mobile elevating work platforms designed to access difficult-to-reach areas. They typically feature a boom mounted on a tracked chassis with outriggers for stability. Their design allows them to operate in confined spaces and on uneven terrain.
What are the key advantages of using a spider lift?
- Compact size for access through narrow spaces and doorways
- Low overall weight and ground pressure for operation on sensitive surfaces
- Flexible outrigger systems for setting up on uneven terrain or in confined areas
- Bi-energy options for both indoor and outdoor use
- Extendable width tracks for increased stability or narrow access
What are the common applications for spider lifts?
Spider lifts are widely used across various sectors including:
- Facility management and building maintenance
- Atrium access work
- Construction and renovation projects
- Tree care and arboriculture
- Historical building restoration
- Locations with sensitive flooring or limited access
- Some models, like the Platform Basket Spider 54T, can even function as mobile cranes
How do I choose the right Spider Lift for my project?
Consider factors like working height required, horizontal reach needed, ground conditions, indoor/outdoor use, and load capacity. Our platform helps you filter and compare Spider Lifts based on these specifications to find the perfect match for your needs. Also consider access constraints, power source requirements, and whether you need specialized features like non-marking tracks.
What safety standards do spider lifts typically adhere to?
Most quality spider lifts are produced according to EN280 norm and comply with international safety regulations. They typically include features like automatic stability and outreach control, moment limiting devices, and automatic cut-out when operating out of level.
What are the different types of power sources available?
Spider lifts can be powered by:
- Petrol engines
- Diesel engines
- AC electric motors (requiring mains power)
- DC electric motors with batteries (including lead acid and lithium ion options)
- Hybrid systems combining engine and electric power
Technical Specifications
What is working height and how is it measured?
Working height is the maximum height a person in the basket can reach. It is typically calculated as the platform height plus the height of an average person (usually 2m).
What is horizontal outreach and how does basket load affect it?
Horizontal outreach is the maximum distance the platform can extend horizontally from the base. The maximum outreach is often dependent on the load in the basket; greater outreach is usually achievable with lighter loads. Most manufacturers provide outreach diagrams showing capacity at different extension points.
What is platform/basket capacity and how many people can it hold?
Platform capacity is the maximum weight the basket is designed to hold. Common capacities include:
- 200 kg (typically one operator plus tools)
- 230 kg (typically two operators plus tools)
- 250 kg (typically two operators plus tools)
- 400 kg (typically multiple operators plus equipment)
What are the typical dimensions of a spider lift basket?
Standard basket dimensions are often around 1.3m x 0.7m x 1.1m or 1.4m x 0.7m x 1.1m. Many baskets are quickly removable and offer rotation capabilities:
- Some with +/-90° basket rotation
- Others with up to 180° platform rotation
What is turret rotation?
Turret rotation is the degree to which the upper structure of the lift can rotate on its base. Many spider lifts offer 340° or 360° non-continuous rotation, while some offer continuous or wider ranges like 450° or even 710° continuous rotation.
What is the overall weight of a spider lift and how does it affect transport?
Overall weight varies significantly by model, ranging from around 1,375 kg to 6,200 kg or more. Lower weight facilitates easier transport, sometimes allowing use of standard trailers. Even larger models like the Platform Basket Spider 54T are designed with simplified transport systems.
What is the travel speed and gradeability of a spider lift?
Typical travel speeds are around 1.5 km/h, but some models can go faster (up to 4.0 km/h) or offer double travel speed settings. Gradeability (the maximum slope the lift can drive on) is often around 28-30%, with some models capable of slightly steeper angles.
What are the stowed dimensions and will a spider lift fit through doorways?
Compact dimensions are a key feature, with some models having a minimum width as low as 0.78m and a transport height under 2m. Several models are specifically designed to fit through standard doorways (approximately 80-90cm width) and even into lifts/elevators.
What are the outrigger dimensions and jacking range?
Outrigger dimensions vary depending on the model and whether they are in narrow or wide setup. Some models feature variable, asymmetrical jacking systems for setup in tight spaces, with multiple stabiliser setting options (typically 3 different setup positions).
What is the ground pressure of a spider lift?
Low ground pressure is an advantage for working on sensitive surfaces. Ground pressure is measured in kN/m² or kg/cm² and varies depending on the model and whether it's stowed or supported by outriggers. This specification is particularly important when working on delicate flooring.
What's the difference between articulated and telescopic Spider Lifts?
Articulated Spider Lifts have jointed booms that can bend and reach around obstacles, making them ideal for complex access challenges. Telescopic Spider Lifts have straight booms that extend outward, typically offering greater working heights and horizontal reach. Many modern Spider Lifts combine both designs with articulated lower booms and telescopic upper sections for maximum versatility.

Yes, many models offer 230V or 110V AC power outlets in the basket. Some may also have 12V sockets for tool charging.
Do spider lifts have a track width adjusting system?
Yes, many models feature a track width adjusting system, sometimes with independent axle control, allowing for narrower transport width and wider operational stability.
Can the basket be removed or rotated?
Many spider lifts feature a quickly removable basket and offer basket rotation (typically +/-90° or 180°) for better positioning in tight spaces.
What safety certifications are required to operate a Spider Lift?
Operators typically need specific MEWP training and certification. In the UK, the most common certification is the IPAF PAL (Powered Access License) with specific categories for Spider Lifts. Always check your local regulations for specific requirements. Employers are responsible for ensuring operators have appropriate training.
IPAF Training
What IPAF categories cover Spider Lifts?
Spider Lifts typically fall under the IPAF categories:
- 1b: Static Boom - Static Vertical (1b)
- 3b: Mobile Boom - All Booms (3b)
The specific category depends on the Spider Lift's design and functionality. Operators should ensure they have the appropriate category for the specific machine they'll be using.
How long does IPAF certification last?
IPAF certification is valid for 5 years, after which operators need to renew their license through a renewal course. It's good practice to maintain regular refresher training, especially if operators don't use Spider Lifts frequently.
Is IPAF training specific to Spider Lifts?
IPAF training covers various types of Mobile Elevating Work Platforms (MEWPs), with specific categories for different machine types. While the general principles apply across platforms, Spider Lifts have unique operational characteristics that require specific training. When booking IPAF training, ensure it includes the specific categories relevant to Spider Lifts.
Operation and Safety
Is remote control standard?
Remote control is a standard feature on many spider lift models, often allowing for both drive and boom operation. Some have cable remote controls, while others offer radio remote control with interactive and multi-lingual displays. Some even offer proportional travel mode via radio remote control.
Do spider lifts have automatic levelling?
Yes, automatic hydraulic outrigger levelling is a common feature, simplifying setup on uneven ground. Many models offer automatic stabilisation/destabilisation systems.

- Daily/pre-use checks by the operator
- Weekly inspections by a competent person
- Six-monthly thorough examinations by a qualified person
- Annual comprehensive inspections and servicing
Always follow manufacturer guidelines and local regulations regarding inspection schedules.
