The Marr Transit System (MTS) extends the reach and capacity of heavy cranes across a project site while decongesting the site and freeing space for the laydown of more building components close to where they will need to be fitted. The MTS does this by having the crane travel along modular rail beams. Placing the crane on rails requires less groundwork compaction because it distributes the weight evenly on the ground underneath. Each wheel is engineered to take a load of 100 tonnes with a maximum corner load of 800 tonnes.
The rails can be lifted and relocated by the crane itself or by other means such as forklift. Having a modular rail system enables a short section to be relocated to extend the operating length, allowing the crane to travel progressively and easily across the length of the site.
The site become decongested because when the MTS is deployed because the rails allow for 8 metres free space between tracks with the standard 10-metre rail centres. The clearance under the base allows for vertical access under controlled conditions. The clearance height can also be increased to suit the needs of a particular project. As a result, ore laydown areas are freed-up across the construction site.
The MTS is designed for use with any crane in Marr’s fleet and there’re no restrictions applied to the operation of the cranes when used in conjunction with the MTS.
The MTS is suited to large construction sites including industrial, mechanical and civil construction works where extensive areas of work need to be covered, and construction works where heavy lifting and travel is required within a limited space. Suitable sectoral applications include new build, retrofits and turnarounds in power generation and oil & gas; rail stations, bridges and airports; ports, harbours, dams, and jetties; data centres; and stadia.
