The tower and mobile cranes setup procedure requires meticulous setup to avoid any catastrophic accidents during lifting operations.
This includes instability and damage caused by:
· Soft and undermined ground conditions
· Hidden utilities and conduits
· Overbalanced cranes
Ground protection mats help you to control for these common crane hazards by spreading the pressure of the crane over a larger area, as well as expanding the base area over which the centre of gravity can be safely located.
Using crane mats to build a lifting platform
First of all, crane safety requires to have a competent person with the relevant safety training to survey the ground in order to identify any hidden hollows and other potential hazards below the surface.
These can create pockets that the crane can fall into – and even a small cavity can leave the crane leaning in a dangerous position.
Crane mats can be used to span smaller spaces below the surface, by ensuring that the pressure is applied over a level lifting platform instead of on a single point of contact.
Widening the base area
Outrigger pads are a way to increase the effective base area of the crane so that the centre of gravity cannot move to an unstable position.
Again, using outrigger mats spreads the pressure of the crane’s outriggers over an area, reducing the risk of crane accidents due to an outrigger sinking into soft ground or breaking through into an undetected cavity.
They also help to create a flat and level surface for the outrigger to make contact with, which can be helpful if the ground itself is not completely level or even.
Things to consider
It’s important to assess the type of outrigger pads and crane mats you need, according to the soil type, the size of your crane or other lifting equipment and the total load you need to lift, among other things.
You might want to consider:
· The size of outrigger mats you need.
· The type and maximum load of crane mats.
At all times, make sure you observe your lifting platform, crane mats and outrigger pads carefully, and halt your lifting operations if you notice any significant deformation.
