Question 1

What is a spider MEWP?

Accepted Answer

A spider MEWP (Mobile Elevating Work Platform), also known as a spider lift, is a compact tracked access platform. It's named after its four independent outriggers that deploy like a spider's legs to stabilise the machine. They are built for the high-reach tasks that standard cherry pickers cannot reach.

Question 2

Is a spider lift considered a MEWP?

Accepted Answer

Yes. MEWP stands for Mobile Elevating Work Platform. In the industry, we classify a spider lift as a 'Static Boom' (IPAF Category 1b). Once the tracks are off the ground and the outriggers are set, the chassis stays stationary while you operate the boom.

Question 3

What is the difference between a cherry picker and a spider lift?

Accepted Answer

The main difference is the chassis and the footprint. A standard cherry picker is usually on wheels or a truck. A spider lift uses rubber tracks to 'walk' into position. They are much lighter and more compact — they can fit through a standard doorway or track over delicate garden lawns where a heavy truck mount would cause serious damage.

Question 4

Can spider lifts operate on slopes?

Accepted Answer

Yes, it's one of their biggest strengths. Unlike wheeled booms that need level ground, a spider lift's independent outriggers can be adjusted to different heights. This lets you level the machine on inclines or uneven terrain before the boom is ever raised.

Question 5

Can a spider lift tip over?

Accepted Answer

A spider lift is very stable, but it can tip if safety protocols are ignored. Modern machines have electronic interlocks that prevent the boom from moving unless the outriggers are correctly deployed. In my 16 years, safety always comes down to the operator's understanding of ground conditions and stabilisation.

Question 6

What qualifications are needed to operate a spider MEWP?

Accepted Answer

In the UK, you need an IPAF Category 1b (Static Boom) licence. Most professional construction sites and insurance providers require this. It ensures the operator knows how to stabilise the unit and handle emergency lowering procedures.

Question 7

What are the main benefits for tree work?

Accepted Answer

Arborists choose spider lifts because of the low ground pressure. The tracks spread the weight, preventing damage to roots and manicured lawns. Their narrow width means a 20m machine can go through a standard garden gate to reach trees in a confined backyard that would otherwise be inaccessible.

Question 8

How do you transport a spider lift?

Accepted Answer

Small models can be towed on a heavy-duty plant trailer behind a 4x4. For the larger 30m+ units, we use a dedicated flatbed or plant lorry. They drive on and off the transport under their own power, making mobilisation very efficient.

Question 9

Can spider lifts work indoors?

Accepted Answer

Yes, they are the go-to for indoor maintenance. Most are 'bi-energy,' meaning they use a diesel engine for outdoors and an electric motor for indoors. Their non-marking rubber tracks protect sensitive interior flooring in shopping centres, atriums, and sports halls.

Question 10

What is the typical height and width of a spider MEWP?

Accepted Answer

Working heights range from 13 metres to over 50 metres. The key advantage is the width—many models are less than 0.8 metres wide when stowed, so a machine with significant reach can go through a standard single doorway.

Question 11

What are the maintenance requirements?

Accepted Answer

Standard maintenance involves hydraulic fluid checks, track tensioning, and greasing pivot points. In the UK, they must have a LOLER (Lifting Operations and Lifting Equipment Regulations) safety inspection every six months to remain compliant and safe for work.

Question 12

Who are the top manufacturers of spider lifts?

Accepted Answer

The market is dominated by specialist brands like Hinowa (the industry standard for tree work), Leguan (all-terrain experts), Platform Basket (highly versatile units), and Falcon Lifts (the leaders in ultra-high reach atrium machines). These are the brands I trust and supply every day.

Question 13

What are the best models for construction vs. tree work?

Accepted Answer

For tree surgery, the Hinowa Lightlift 20.10 is the professional favourite. For construction and cladding, I often recommend the Leguan 225 because it's built for rougher site terrain and heavy-duty use. It all depends on your specific site constraints.

Question 14

When should I choose a spider lift over a standard cherry picker?

Accepted Answer

Choose a spider lift if you have weight-sensitive surfaces (like gym floors or suspended slabs), narrow access constraints, or soft ground where a wheeled cherry picker would sink. If the job is awkward or tight, a spider is almost always the better choice.
