Mobile Conveying Services caters for all aspects of the Construction industry.
Unloading trucks bringing bulk material to site
Truck unloaders allow tippers to discharge close to the entry of a site or even outside the site, speeding turnaround. The unloader can feed transfer conveyors or a stacker conveyor, minimising the need for haul roads within the site.
Stockpiling material on site
Bulk material brought to site or crushed and screened from on site materials can be stockpiled using a stacker. These can be readily moved about the site as required, and can also be used for placing materials in areas than cannot be safely reached by dumpers.
Transferring spoil from a deep excavation
The belt on a Telebelt is bi-directional, so that the telescopic belt can be used to draw excavated material from a basement and load tippers on the street, avoiding the need for a ramp and wheel wash.
Transferring bulk material in areas with restricted or no vehicle access
Where there is insufficient room on site for using dump trucks or where the congestion would be unacceptable, mobile and portable transfer conveyors can be used for moving bulk material on site. Conveyors can also be used for transferring material in environmentally sensitive areas, or placing material in areas where it is unsafe to have mobile equipment working e.g. close to the edge of an excavation.
Conveyors can also be considered for transferring spoil off site to a suitable transfer or disposal location where having tippers access the site through unsuitable local streets would cause significant disturbance to residents.
Backfilling behind retaining walls
Often the ground conditions mean that a wheel loader cannot get close enough to safely backfill behind a retaining wall. A Telebelt can set up away from the wall and close to a stockpile of backfill material. It can cover a long section of wall before relocating, minimising the number of stockpiles required.
Feeding kerbers and pavers
A Telebelt can place concrete across the full width of a tracked or rail-mounted paver and maintain a high feed rate. There is no disturbance to reinforcing mesh.
Telebelts can also be used to feed the hopper of a slipform machine, and have been used to feed the hopper from a different ground level where it was impractical to block a lane of traffic for an agitator.
Handling unpumpable concrete
Conveyors can handle unpumpable concrete such as RCC. Conveyors have routinely been used around the world for decades on RCC dam projects where high transfer rates and reliability are required.
Mass concrete pours
The practical transfer rates of conveyors are significantly greater than can be achieved with a concrete pump, meaning that generally fewer machines are required or placement time is reduced. Mobile conveyors are reliable in prolonged operation, and have proven themselves in ship loading applications. This means that there is less chance of a breakdown disrupting a large pour. The transfer rates mean that multiple agitators can back up to a conveyor feed hopper. There is also less segregation in belt transfer than in a pump, and stiff concrete mixes can be handled with a belt.
Backfilling over culverts
Where multiple large diameter culverts are installed, backfilling is beyond the reach of conventional earthmoving equipment. A telescopic conveyor can accurately place backfill material and avoid the risk of damaging any geotextiles or barriers used behind the culvert.
Backfilling where machine access is not possible
Telebelts come into their own where there are wide trenches with multiple pipes to be backfilled, underground water or other storage to be covered or geotextile that can be damaged by machine movement.
Placing sandbags for formwork
Sandbags are sometimes used as formwork in applications where conventional formwork is impractical e.g. around pipes. Sandbags can be transferred by conveyor, providing a practical, safe and productive solution to a problem that might otherwise require craneage or manual handling.
