Slew Bearing Replacement on a Ship Loader

Slew Bearing Replacement on a Ship Loader

Replacing the slew bearing on the 40 year old (grain) ship loader required lifting the upper structure 300 mm to provide adequate clearance during replacement. Keeping the boom connected made it challenging to maintain the balance of the ship loader during the lift. Maintaining the center of gravity of the ship loader throughout the lift was critical.

Replacing Rail Bridge Decks with a Hydraulic Gantry

Replacing Rail Bridge Decks with a Hydraulic Gantry

Timing is critical for rail construction projects to avoid unscheduled disruption to train and passenger services. However, the best project planning can be undermined by adverse weather conditions. High winds, greater than 12 mph, may prevent bridge deck lifting using a crane, leading to project delays.

Stud Removal on a Stacker Reclaimer with Hydraulic Tensioners

Stud Removal on a Stacker Reclaimer with Hydraulic Tensioners

Removing the 3 meter long studs on the bucket wheel drive output of a Sandvik stacker reclaimer is a difficult and lengthy operation. Operating conditions corroded the studs and the confined location of the stud does not allow access with traditional removal equipment. Previous operations required more than 10 hours to remove each stud and used up to 120 tons of force to push and pull a total of 16 studs.

Removal of Decommissioned London Tube Trains with a Hydraulic Gantry

Removal of Decommissioned London Tube Trains with a Hydraulic Gantry

Nine London Underground 1983 model stock trains were decommissioned and abandoned in the South Harrow sidings in 1998 when the 96 model stock trains were introduced. The poor condition of the 83 train cars made it unsafe to haul out onto the network to a depot. Sonic Rail Services were contracted by the Station Works and Improvement Program (SWIP) of London Underground to remove the carriages from the South Harrow station sidings, with minimal disruption to the network and to undertake the necessary remedial repairs to the track.

Lifting an Underground Mining Truck to Fix a Flat Tyre

Lifting an Underground Mining Truck to Fix a Flat Tyre

Changing a flat tyre on heavy machinery is one of underground mining’s most hazardous and time-consuming maintenance tasks, often taking up to 12 hours to complete in confined spaces with sloped surfaces.

Tunnel Boring Machine Launched with EVO Synchronous Lifting System

Tunnel Boring Machine Launched with EVO Synchronous Lifting System

The construction of the 4.5 km Waterview Connection motorway included the deployment of an Earth Pressure Balance Machine to bore a 2.5 km underground twin tunnel. Commencing the tunneling process required positioning the 3,600 ton tunnel boring machine into its starting position.

Hydraulic Boom Gantry Safely Transports 120 ton Machine Bed

Hydraulic Boom Gantry Safely Transports 120 ton Machine Bed

Gushee's Rigging and Heavy Hauling, the premier machinery mover in New England, was tasked to safely transport a 243,000 pound machine bed for one of its customers. The machine bed had to be unloaded from a truck, uncrated and placed in a 6-foot deep pit inside a building.

Enerpac Self-Erecting Tower Lifts Petrochemical Hydrocracker Vessels

Enerpac Self-Erecting Tower Lifts Petrochemical Hydrocracker Vessels

Spectyazh was tasked to lift and position two hydrocracker vessels, each weighing 1,306 tons and measuring 48 meters in height. Initially, Spectyazh considered existing means to lift and replace the hydrocracker vessels, including the use of heavy cranes. However, given the space-restricted area of the petrochemical construction site, there was very little space to maneuver and lift the vessels, and cranes would not fit.

Replacing the Elvira Railroad Bridge Span with a Jack-up System

Replacing the Elvira Railroad Bridge Span with a Jack-up System

The Elvira Railroad Bridge, built in 1906, spanned across the Cahaba River in Helena, Alabama. The old double-track open deck superstructure had reached the end of its useful life and was scheduled for replacement with a new single-track ballasted deck superstructure. Burkhalter, lifting, rigging and transport professionals, was selected to execute the replacement of Span 2 over the river.
