Marr’s Engineering Department provides design and engineering support in the area of suspended scaffolds and swing stages. Marr routinely provides custom designed rigging solutions for our clients. We are able to do this, in part, due to the exceptional level of manufacturer support we receive on a daily basis. This support includes custom rigging designs […]
Marr frequently designs and implements Systems Scaffold to support rigging beams (roof rigging) in order to overcome challenging roof conditions that preclude the use of traditional pre-engineered roof rigging. These designs often require design and PE stamping prior to installation. Marr’s extensive experience with Systems Scaffold is an increasingly important and well utilized tool in […]
Parapet Clamp Parapet clamps and roof hooks are the simplest method of rigging on structural parapets. The lightweight Adjustable Parapet Clamp has an outreach from 16 to 24 in. Quick pins allow for fast and easy adjustments. Weighs less than 50 lbs., making it easy to transport, install and produce to quickly. 1,500 lb maximum […]
Davit Arm Davits are permanent installations that are a great rigging solution for repetitive jobs.
OBSF-4 Rigging Entire system disassembles to fit in standard elevator. Cast iron counterweights fit into slots on frames for positive attachment. System is easy to transport and assemble. Applications: Use two assemblies for 2-point suspended platforms (i.e. stages and modular work platforms). Use one assemble for 1-point suspended platforms (i.e. cages, Bosun’s chairs, etc.) OBSF-4 […]
Extended Reach Beam, 5×5 Delivers an increased overhang of up to 11’, with the standard having only a 2’-3’ overhang.
Tilt-Up Beam Simplest method for lifting an outrigger over a parapet wall. Multiple adjustments for use with a 16 or 24 ft. beam assembly. Max outreach: 4’ – 9” Parapet clearance at lowest point: 4 – 4”
Standard Outrigger Beam, 5×5 The rolling roof rig allows for the rapid movement of the outriggers to the next drop 16’ and 24’. This highly modular system can be configured many ways to meet 95% of your outrigger beam applications.
