Lindapter Girder Clamps delivered a practical solution to suspend a Mero rigging system.
Project Background
Location: Frankfurt, Germany
Product: Type AF Girder Clamp
Market: Arts & Entertainment
Client: Messe Frankfurt
Contractor: Ernsthaus Rigging Services
The Festhalle is an architecturally and historically important building which at the time of its completion in 1909 had the largest dome in Europe. The dome reaches a height of 40 metres and looks down on 5,646m2 of space which is used to hold events and concerts. Internally the original arched steel roof trusses and dome structure can be seen, and are used to suspend modern rigging equipment.
Client Requirement
The shackle suspending the rigging from the steel roof structure needed to be replaced because of additional high frictional loads caused by the weight of a new rigging system and equipment. Welding or damage to the steel already in place structure was not permitted because of the historical importance of the building, and so a new method of connecting to the steel was required. The solution would also need to be capable of carrying the necessary loads and prevent frictional slip.
Design Solution
Lindapter in conjunction with the rigging contractor designed a bespoke bracketry system. This included two large adjustable plates that attached to either end of a steel arm to spread the load. The plates would then be connected to the existing steel using Type AF high slip resistance girder clamps to provide the necessary combined loads of tensile and slip, particularly at the outer edges of the roof where loads were the greatest.
Installation
Each bracket arrangement was carefully lifted into position and then fixed at the point of contact between the adjustable plates and the steel roof trusses. A combination of size M16 Type AF girder clamps, washers, packing pieces and spreader bars were used for each connection. For the brackets on the outer edges of the roof as much as ten girder clamps per plate were fitted to provide the necessary high slip resistance. After each bracket was secure the contractor could suspend the Mero rigging system from the steel arm which was then used to install lighting and other equipment.
Result
Lindapter Type AF Girder Clamps provided a drilling and weld free connection that prevented any damage to the steel already in place trusses. They have independent technical accreditations, which include the CE Mark (ETA-13/0300), T?V and Lloyd's Register approvals which verify the high load and slip capacities, leading to a safe and effective installation.
Principal advantages
High slip resistance for tensile and frictional loads
No drilling or welding required
Hot Dipped Galvanised finish offers a economical and low maintenance solution
