Crane Outrigger Pads Requirements: Stay Safe, Stable and Compliant with APS

Every lift starts from the ground up. Whether you’re operating a crane, spider lift, or truck-mounted platform, the stability of your machine depends on the strength of the surface beneath it, and that’s where outrigger pads make all the difference.

Outrigger pads are essential for crane and MEWP stability. LOLER and BS 7121 require pads that evenly distribute load and prevent ground failure. APS supplies durable polyethene outrigger pads across the UK, helping businesses meet safety standards and maintain reliable lifting performance on every project.

Outrigger pads distribute a machine’s weight evenly across the ground, reducing pressure and preventing the equipment from tipping or sinking. Using the right pads isn’t just best practice; it’s a legal requirement under the UK’s LOLER and PUWER regulations.

At APS, we supply a comprehensive range of high-performance outrigger pads for cranes, access platforms, and material lifts. Backed by our nationwide servicing and aftercare support, we help businesses stay safe, compliant, and operational on every site.

Why Outrigger Pads Matter

Every lifting operation creates immense downward pressure through a machine’s stabilisers. Even seemingly solid ground can compress or shift when heavy loads are applied, causing instability.

Outrigger pads spread the load over a larger area, reducing ground bearing pressure (GBP) and creating a safer, more stable working platform. They’re especially important when working on:

• Soft or uneven ground
  
• Paved or asphalt surfaces
  
• Grass or soil
  
• Unknown sub-base conditions
  

Incorrect pad use is one of the most common causes of crane or MEWP instability. A simple oversight in ground assessment can lead to serious incidents, costly downtime, or equipment damage.

APS outrigger pads are designed to deliver consistent strength, durability, and grip, giving operators confidence that their equipment is stable and compliant in all conditions.

Legal and Industry Requirements

Using suitable outrigger pads isn’t optional. It’s part of your legal duty under LOLER (Lifting Operations and Lifting Equipment Regulations 1998) and PUWER (Provision and Use of Work Equipment Regulations 1998).

Both regulations require lifting equipment to be:

• Strong and stable, suitable for its intended task.
  
• Used in a way that minimises risk to people and property.
  
• Properly maintained, inspected, and operated by trained personnel.
  

The British Standard BS 7121 – Safe Use of Cranes also specifies that the ground must be assessed for stability before any lift begins. This includes:

• Calculating ground bearing pressure (GBP).
  
• Selecting outrigger pads that are large and strong enough to spread the load safely.
  
• Recording outrigger arrangements in the lift plan.
  

Failure to meet these requirements can lead to enforcement from the Health and Safety Executive (HSE) and invalidate insurance cover.

APS supports compliance across the board. Our engineers assess stabiliser and load-bearing systems during LOLER inspections and can advise on safe ground support as part of our aftercare service plans.

Choosing the Right Outrigger Pads

Selecting the right pad size and material is critical to safe lifting. The correct pad depends on the machine type, total weight, load, and ground conditions.

Key factors to consider include:

• Machine weight and load: Total weight distributed across all outriggers.
  
• Number and position of outriggers: Load distribution changes depending on configuration.
  
• Ground type: Soft soil, tarmac, and compacted gravel each require different pad sizes.
  

To check suitability, calculate ground bearing pressure using:

Load per outrigger ÷ Pad area = Ground pressure (kN/m²)

This figure must be lower than the site’s safe ground bearing capacity.

Material choice matters too. APS outrigger pads are made from ultra-high-molecular-weight polyethene (UHMWPE), a lightweight, non-corrosive, and impact-resistant material that won’t splinter or absorb moisture.

Compared with steel or timber alternatives, UHMWPE pads are easier to handle, safer to transport, and more durable over time.

APS supplies pads in a variety of sizes and thicknesses, suitable for cranes, spider lifts, and truck-mounted access platforms. Our team can recommend the correct pads for your equipment and environment, ensuring full compliance with LOLER and BS 7121.

Best Practice for Using Outrigger Pads

Using the right pads is only part of the safety equation; how they’re used and maintained is equally important.

Before use:

• Inspect pads for cracks, deformation, or surface contamination.
  
• Ensure the ground is compacted, level, and capable of supporting the load.
  
• Position pads directly under the outrigger foot, centred and level.
  

During operation:

• Check that the pad remains stable and fully in contact with the ground.
  
• Avoid lifting if pads are rocking or sitting unevenly.
  
• Monitor ground conditions, rain, temperature, or vibration, which can change support characteristics.
  

After use:

• Clean pads to remove oil, soil, or debris.
  
• Store flat, out of direct sunlight, to prevent warping.
  
• Replace damaged or distorted pads immediately.
  

APS aftercare service engineers include outrigger inspections as part of regular equipment servicing, helping to spot wear or damage before it compromises safety.

How Long Do Outrigger Pads Last?

A well-made outrigger pad should last for many years if properly used and maintained. The lifespan depends on several factors, including frequency of use, load weight, ground conditions, and storage practices.

APS outrigger pads are manufactured from high-quality UHMW polyethene, which offers exceptional durability and resistance to cracking or splitting, even in extreme temperatures. Under normal conditions, these pads can easily last five to ten years or longer.

To maximise lifespan:

• Inspect pads before every use.
  
• Clean regularly and store flat.
  
• Avoid sharp edges or debris that can cut the pad surface.
  
• Keep them away from oil or chemical spills that could degrade the material.
  

Signs that your pads may need replacing include:

• Visible cracks or gouges
  
• Warping or distortion
  
• Reduced grip or uneven surface contact
  
• Contamination that can’t be cleaned off
  

APS Aftercare engineers can inspect outrigger pads during LOLER or service visits, advising when replacements are due. We also offer fast delivery of replacement pads across the UK, keeping your fleet safe and compliant without delay.

FAQs

Are outrigger pads required by law?
Yes. LOLER and BS 7121 require lifting equipment to be used safely and on stable ground, meaning suitable outrigger pads must be used for every lift.

How do I know what size outrigger pads I need?
Calculate the load on each outrigger and divide by the pad’s surface area. The result must be less than the ground’s bearing capacity. APS can help determine the right pad size for your equipment.

What are outrigger pads made of?
APS pads are made from ultra-high-molecular-weight polyethene (UHMWPE), a material known for strength, impact resistance, and long service life.

Do access platforms need outrigger pads, too?
Yes. MEWPs, spider lifts, and material lifts often require stabilising pads, especially when used on uneven or soft surfaces.

How long do outrigger pads last?
With proper use and maintenance, APS pads can last between five and ten years or more. Regular inspection is essential to maintain safety and compliance.
