It is an essential requirement, that the supporting surface for a fixed crane (Crane Base) must be engineered and certified by an authorized and fully qualified structural engineer. Active Crane Hire provides the Engineering Service at very competitive rates as we believe that experience of structural engineers in crane base designs is once again the main driving force to deliver the right product and to keep the costing under control. Although we do offer our clients the choice of using their own engineer we prefer to do the service in house.
