How could tandem lifting benefit you?


Boost Productivity 

Lifting more containers per cycle will improve your operational consistency and drive up your revenue.

Save Energy 

Lifting more containers per cycle will mean your equipment is working less and also using less energy.

Save on Costs

As your energy demand is less, your container operations will cost less money leading to an increase in revenue.

Be Flexible

By controlling the gap, skew, longitudinal offset and height difference between containers, your operations will run smooth.
