Consider factors like working height required, horizontal reach needed, ground conditions, indoor/outdoor use, and load capacity. Our Spider MEWP Matrix 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.

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.

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

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).

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 like Hinowa, CMC, and Teupen provide outreach diagrams showing capacity at different extension points.

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)

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

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.

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.

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.

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 from manufacturers like Hinowa and CMC are specifically designed to fit through standard doorways (approximately 80-90cm width) and even into lifts/elevators.

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). Compare outrigger specifications for different models in our Spider MEWP Matrix.

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. See our Point Loadings Guide for more information on ground pressure considerations.

Articulated Spider Lifts have jointed booms that can bend and reach around obstacles, making them ideal for complex access challenges.

Point loadings refer to the concentrated surface pressure (CSP) that a spiderlift's outriggers exert on the ground. Hinowa, for instance, considers CSP as the most accurate metric for measuring these loads. It's calculated based on the reaction force from each outrigger and the area of its footpad, determining the pressure applied to the surface (e.g., in daN/cm² or KN/M²).

Understanding point loadings is critical for safe and effective spiderlift operation because if the underlying ground or structure cannot support this concentrated pressure, it can lead to instability of the machine, damage to delicate surfaces, or even structural failure. For projects with strict limitations on ground pressure, such as maintenance work on wind farm crane pads, specialized solutions like multi-mat systems are used to distribute the load more widely and achieve the required point loads. Matthew Dean has been directly involved in projects requiring precise point load management, ensuring that the right equipment and support systems are in place. It is always recommended to check the specific point loading values for your machine and consult with an architect if there are any doubts about ground bearing capacity.
