SPI/Mobile Pulley Works is a supplier of dredges, complete dredging installations for both CSD and TSHD, large fabrications, castings, and machined parts for the dredging industry. Mike Hooks LLC, family owned and operated since 1945, is providing dredging services for government and private marine construction contractors. This dredger will be delivered by SPI/Mobile Pulley Work in the second quarter of 2022. The idler barge can be connected as well to the under-construction state of the art 27-inch cutter suction dredger.
#DREDGE BARGE UPGRADE#
The idler barge is the first upgrade and innovating of Mike Hooks current fleet. All the movements are hydraulicly driven, the spud can be fully controlled from the lever room and is a one-man operation. The idler barge is set to increase the production with approximately 25% compare to the fixed spud system. The idler barge, fabricated at SWSLP Shipyard in Galveston and equipped with SPI Mobile Pulley Works spud installation, will be connected to the cutter suction dredger (CSD) Missouri H., and will be starting operation in Gulfport, Mississippi, in the following weeks. They are often used for bulk dredging of a variety of sediments.SPI/Mobile Pulley Works has delivered a brand-new Idler Barge to Mike Hooks LLC. The new, much larger backhoes that have been delivered in the last few years are able to dredge at greater depths, some in excess of 30 meters.

They can be used for dredging relatively small quantities of material at varying depths. Dredging barges illegally operated by miners converge on the Madeira river on November 25, 2021.

Smaller backhoes can be track mounted and work from the banks of ditches especially when being used in harbours or other shallow waters, as well as in access channels and harbours along quay walls that are difficult to reach. Project applicationsīackhoe dredgers are often used in foreshore protection operations. The capacity of the barges also determines how quickly the backhoe works. The material is excavated, brought to the surface at or near its in situ density, and placed in barges for transport to the placement area. Production rates are clearly dependent upon the bucket size and the average percentage of the bucket’s filling, which is in turn influenced by the type of material being dredged. Normally speaking, these barge-mounted backhoe dredgers have a moderate production rate. Although some backhoes are self-propelled, the majority of smaller backhoes must be towed or transported to the work site. They are usually stationary, requiring strong spuds, or occasionally anchors, to keep them stable and to fix them at the desired dredging location. Limitationsīackhoes do have limitations both in their radius of movement and the depths they can reach. These include sand, clays, gravel, cobbles and fractured and unfractured moderately strong rock. Types of materialīackhoe dredgers are flexible and versatile and can be employed for dredging a variety of materials in access channels and close to shore. The largest backhoe dredgers are transported by water with spuds that are designed to be tilted out of the water.
Some newer backhoe pontoons may be self-propelled which offers more mobility between work sites. Custom-designed backhoe dredgers can dig at greater depths and have greater total installed power and therefore can be utilised more extensively and cost-effectively for larger projects. Advantagesīackhoe dredgers have become more and more popular for dredging and the modern backhoe dredger is now treated as one of the main classes of dredging vessel. In dredging operations both land-based and water-based backhoes may be used. It refers to the action of the shovel, which digs by drawing earth backwards, rather than scooping material with a forward motion like a steam shovel or a bulldozer or a dipper. The word “backhoe” does not refer to its location on the back of a vehicle or pontoon. The water-based backhoe dredger is a stationary, hydraulic crane mounted on a dedicated dredging pontoon that often has a rotating table.
“Backhoe dredgers” are water-based excavators that evolved from the land-based backhoe. Land-based backhoes are typically mounted on the back of a tractor or front loader that has an undercarriage with wheels or with tracks. “Backhoes” are hydraulic excavators with a single digging bucket positioned on the end of a two-part articulated arm.
