The Most Common Mistakes When Choosing Crane Mats 

Selecting the right crane mats is critical to safe lifting operations, yet preventable mistakes remain common across construction and infrastructure projects. Understanding these pitfalls, and how to avoid them, protects both personnel safety and project timelines, whether you’re using mats for the first time or refining your approach based on years of experience. 

These mistakes don’t usually stem from carelessness. They’re more often the result of time pressure, incomplete ground information, or assumptions carried over from previous jobs.  

Too often, crane mats are treated as an accessory rather than a core part of the lifting plan, despite the enormous forces passing through them. As a specialist timber mat supplier, we regularly see the same issues repeated – and the good news is that they’re entirely preventable with the right knowledge. 

Overloading a Crane Mat: Possible Setbacks 

Underestimating load requirements is one of the most serious, and most preventable, mistakes in crane mat selection. 

Understanding the Real Forces at Play 

Crane mats must support far more than the crane’s static weight. Outrigger loads, lift radius, slewing movements and dynamic forces all increase pressure on the ground. If crane mats are under-specified, failure can occur quickly and without warning. 

Consequences of Inadequate Load Capacity 

Common consequences of overloading include: 

  • Excessive mat deflection that compromises crane stability 
  • Outrigger punch-through causing sudden level changes 
  • Ground collapse beneath lifting points during critical operations 
  • Crane instability leading to serious safety incidents 

How Timber Crane Mats Distribute Load Safely 

Timber crane mats are engineered to spread heavy loads evenly across a wider surface area. Dense hardwood options maintain stiffness and structural integrity under intense pressure, reducing the risk of settlement during critical lifts. When specified correctly, they provide predictable, consistent performance even under maximum rated loads.

Choosing the Wrong Bog Mat Size for Soft Ground 

Ground bearing capacity varies dramatically between sites, yet mat sizing is often based on assumptions rather than actual conditions. 

Why Undersized Mats Fail on Soft Ground 

On soft, saturated or recently disturbed ground, undersized bog mats concentrate pressure rather than distributing it. This increases the risk of sinking, rotation and loss of level during lifts, particularly as loads shift or environmental conditions change throughout the working day. 

Critical Sizing Factors for Challenging Ground 

Soft ground conditions require: 

  • Larger surface area to reduce ground bearing pressure 
  • Increased thickness for stiffness and load distribution 
  • Materials that cope with uneven settlement without cracking or failing 

Timber’s Natural Advantage 

Timber bog mats perform especially well in these situations due to their strength-to-weight ratio and slight natural flex, which helps them adapt to imperfect ground while maintaining structural integrity. Unlike rigid composite alternatives, timber distributes point loads more effectively across the entire mat surface. 

When Ekki Mats Should Be Mandatory but Aren’t 

Not all lifting environments demand the same level of performance, yet material upgrades are often overlooked when they matter most. 

What Makes Ekki Different 

Ekki timber is one of the strongest hardwoods used in ground protection, offering exceptional density, durability and resistance to moisture degradation. Despite this proven performance, some projects continue to rely on lower-grade mats in situations where failure risk is genuinely high. 

When Ekki Should Be Non-Negotiable 

Ekki crane mats should be the default choice when: 

  • Outrigger loads are extremely high (heavy-lift or crawler crane operations) 
  • Ground conditions are persistently wet (tidal work, waterlogged sites, winter projects) 
  • Long-term settlement cannot be tolerated (precision lifting, extended site duration) 
  • Environmental sensitivity demands minimal ground disturbance

Choosing Timber Is Choosing Safety 

Material choice and proper specification are the determining factors between safe operations and preventable incidents. 

Timber crane mats remain the industry standard because they deliver predictable, proven performance in real-world conditions where safety margins matter. Whether you’re new to crane mat procurement or optimising your existing operations, understanding load requirements, ground conditions and material performance ensures every lift starts on solid ground.
