How to Hire a Spider Lift in the UK: Site Planning Checklist

Hiring a spider lift (tracked access platform) can solve access problems that standard cherry pickers or scissor lifts simply cannot touch. From working inside shopping malls and historic churches to navigating narrow garden gates or muddy slopes, spider lifts are specialist tools for awkward access.

However, because they are specialized, high-performance machines, hiring one requires more planning than a standard boom lift. Getting it wrong can lead to costly delays, damaged surfaces, or the machine being turned away. This checklist will help your hire run smoothly from booking to drop-off.

1. Access Widths and Heights (The Stowed Dimensions)

The primary reason people hire a spider lift is to squeeze through tight gaps. Most 15m to 20m spider lifts can narrow down to under 800mm wide and under 2m tall. This allows them to pass through standard single doorways or garden gates. However, you must measure the entire route:

• Narrowest gateways or doors: Take off another 50mm for clearance to avoid scraping the tracks or paintwork.
• Right-angle turns: A machine that is 4.5m long might fit down a 1m wide corridor, but it won't turn a tight corner without significant room.
• Overhead obstructions: Look out for low arches, pipes, or light fixtures along the travel path.

2. Ground Conditions and Point Loads

Spider lifts are relatively light compared to standard self-propelled booms. They crawl on rubber tracks, which spreads weight out and reduces ground pressure during travel.

However, when the machine is set up, it lifts itself entirely off its tracks and rests on four outriggers. This is where point loads become a critical factor. You must consider:

• Underground services: Basements, cellars, drainage pipes, and cable ducts.
• Floor loading capacity: If working inside on tiles, raised floors, or marble, verify the floor can handle outrigger pressure.
• Spreader pads: Standard plastic outrigger pads are usually provided, but for soft ground or sensitive tiles, you may need large timber or heavy-duty composite mats.

3. Operated vs. Self-Drive Hires

Should you hire a machine and operate it yourself, or pay for an experienced, IPAF-qualified operator?

If you have an IPAF Category 1b licence, you are legally qualified to operate tracked platforms. However, spider lifts have specialized control systems and setup procedures. If your job is in a high-traffic area or requires complex positioning, operated hire is often the practical choice.

4. Power Source Selection

Most modern spider lifts are bi-energy. They usually feature a diesel or petrol engine for outdoor travel and positioning, coupled with a 110V/240V mains electric motor or a lithium-ion battery system for indoor, zero-emission use.

• Indoor use: Check that the site has a reliable 110V or 240V power source near the setup location, or specify a pure Lithium battery machine.
• Outdoor use: Check fuel access. Diesel is standard, but some smaller spider lifts use petrol.

5. The Site Survey: De-risking the Setup

The best way to prepare for a hire is to have a professional site survey completed before booking. This is what I do day in, day out at Wilson Access.

I visit your site, measure access routes, calculate outrigger loads, check ground slope limits, and specify the exact machine needed. This removes guesswork and protects your project timeline.
