Airport, Seaport Profits Take Off with MB Crusher
Working to demolish, redevelop, and build on seaports and airports has many constraints due to the constant flow of arrivals and departures throughout the day and night. To be competitive, contractors must follow a schedule and avoid going over our budget. That’s why many turn to MB Crusher to find a solution that helps them improve operations and increase profit.
When managing remediation work at seaports or airports, operators must deal with large quantities of waste material that needs to be crushed or hauled to a landfill. The costs of transporting and processing the material also weigh on the final budget. To eliminate these expenses for a port remediation project in Dublin, the contractor installed a BF120.4 crusher bucket on their excavator to crush demolition waste. Along with eliminating transportation and disposal costs, the contractor recovered the material for reuse in constructing a new eight-story building. Since the unit was installed on the excavator, MB’s crusher bucket arrived on site quickly and without incurring additional costs.
Handling debris requires many trucks going to and from the construction site. At an old Tripoli airport, a company used a BF120.4 crusher bucket to recycle the rubble from the buildings destroyed by a bombing, then reused the material as a substrate for future road construction projects. A similar problem also arose at an airport in Hong Kong where managing time and resources was essential to keep the traffic flowing. Using the BF135.8 crusher during some of the buildings’ renovations made it possible to recycle all the material without the need for other machines.
When it comes to renovations at a seaport, factoring in time is essential to avoid slowing down daily operations such as loading/unloading goods and passengers. In Conarky, Guinea, the seaport has invested more than US$300 million dollars in renovating the container terminal and storage area’s deformed flooring. Every year, this seaport records about 2 million tons of goods that arrive and leave their docks.
The project team was tasked to remove the self-locking concrete blocks, reinforce the subsoil, and lay down new concrete--all on time or even ahead of schedule, if possible, to avoid hindering commercial activities. Using MB Crusher’s BF80.3 crusher bucket, the contractor crushed the blocks down to an output size between less than 1 in (3cm) and then distributed the materal over the substrate, creating an excellent mixture capable of withstanding heavy loads. All of the work was done by reusing waste material and without trucks transport
When working close to the ocean and having limited space, it is essential to work with precision.
This was the case at an important port in Japan, where a long anti-storm barrier needed to be raised by 3 ft (1m). The contractor needed to mill the concrete exterior to ensure that the new casting would adhere to the old surface, guaranteeing impermeability, stability, and external drainage of water. MB Crusher’s drum cutter ground the reinforced concrete layer without damaging the original structure.
