The barge carries a shear legs crane which is the largest barge crane ever used on the U. West Coast. The barge's name is taken from " Left Coast ", a slang term for the West Coast of the United States which appears on the left side of a typical map and also refers to the region's liberal, or "left leaning", political tradition.

The barge was built in Portland, Oregon by U. Ltd ZPMC. Before Left Coast Lifter was fitted out with the crane for bridge construction, it was deemed to violate the Jones Actspecifically in that since the integral crane would be built and installed in China, it could not be used to transport goods by water between U.

Therefore its first job, prior to installation of the crane, was to haul dredged materials to Long Beach. After Left Coast Lifter arrived at the Bay Area in March[6] it was used to place pre-fabricated falsework truss sections and the 28 box girder deck sections.

The massive crane was being used for heavy lifts of large bridge sections, [21] and placed the final steel girder for the new Rockland-bound westbound span in October The eastern span of the old Tappan Zee Bridge was dropped into the Hudson via controlled detonation in January ; although the intent was to dismantle the bridge in place, during opening celebrations for the replacement Mario M.

Cuomo Bridge in Septembera loud pop was heard and the original Tappan Zee bridge was closed to workers, as engineers determined it had become unstable. The Federal Highway Administration approved a revised plan to detonate the original bridge's supports in December Left Coast Lifter was also used for a heavy lift during the summer maintenance of the Spuyten Duyvil Bridge ; the crane moved the swing section of the bridge onto a barge in June to facilitate work on electrical and mechanical equipment that had been damaged during Hurricane Sandy.

While transporting the sheerleg, the heel pin support may be moved towards the bow of the barge in order to lower the boom and the overall profile of the barge, facilitating transport. From Wikipedia, the free encyclopedia.

Typically, lifting clamps are used in pairs, attached to chains or rod hangers, and grip the end or corner flanges of an object.

There are two main types of clamping action. The screw bolt type of lifting clamp is attached to the load and tightened manually. The lever type utilizes the lever action of a cam, and its clamping force is determined by the mass of the load itself.

Lifting Devices

Lifting clamps are usually made of steel and coated to resist corrosion. They feature a body, a lifting eye that secures the hoist or rigging, a bolt or cam segment, and often a safety latch or locking mechanism. They will often have a toothed profile on one or both clamping edges for a more secure grip.

Lifting clamps are designed to suit a specific application, and these include plate clamps, beam clamps, piling clamps, rail clamps, girder clamps, and scissor grabs. In addition to hoisting, lifting clamps can be used for pulling equipment, tensioning loads, or holding items in place.

Any usage restrictions will also be listed. Lifting clamps vary in their capability for vertical, horizontal, and universal or multi-directional lifting, so it is important to select clamps that are suitable for the application and load material. Lifting clamps are used in factories and warehouses, fabrication plants, ports and docks, and construction sites, among others.

They may feature several crane girder layouts such as single girder, double girder, or bridge girder designs. The configuration depends largely on the headroom in the building and the loads the crane is designed to lift.

A crane girder is subjected to a variety of often severe stresses during lifting operations and special attention should be paid to rating, reinforcement, and periodic inspection and maintenance.

Crane girders are generally heavy I-beam steel members which provide a stable track for on which overhead cranes travel. Depending on the type of installation, overhead cranes typically have between one and three crane girders. The crab or traveling head of the crane is fitted with a set of rollers which either run on the top or on the bottom cross member of the I beam.

In single girder installations, only a crab girder is used. In double girder or bridge cranes, the crab girder is fitted with carriages at either end and moves up and down the loading space on two additional crane girders.

Single crane girder installations are useful in applications where no transverse movement is needed. Also known as monorail cranes, these machines can travel the length of the girder and lift or lower loads only. This type of crane is useful in narrow spaces where load movement is restricted to the length of the space.

These cranes generally run on the bottom of the girder which is typically supported at several points along its top cross member.

One disadvantage is reduced hook height because the crab and hook is usually located under the crane girder. Bridge and double girder cranes are far more flexible and allow 3-dimensional hook movement. In these installations, the crab can move across the crane girder to cover the breadth of the space.

In addition, the crane girder assembly can move along the length of the space covering a far wider area than a monorail. This type of crane has the additional benefit of having the crab girder run on top of the side support beams or be raised to run between them.

This allows for extended hook heights and improved flexibility. Crane girders, particularly the crab girder, are constantly subjected to a number of stress loads during operation. These include vertical stress exerted by the load, lateral stress caused by acceleration and braking of the crab, and transverse stresses caused by swinging of the load. Crane girders are often reinforced with flat plates or channels along their mounting cross sections to resist these stresses.

To ensure the safety of operating personal and the loads the crane transports, crane girders need to be correctly rated and regularly inspected for signs of damage.

What Is a Plate Girder Bridge? What Is a Box Girder? What Is a Monorail Hoist?When it comes to bridge designadvancements in technology often take a long time to be widely accepted. After all, if a technique has been proven to work, why reinvent the wheel? For some time, this has been the thinking when it comes to spliced girder bridges. Traditionally, spliced girder bridges have been used for continuous structures to facilitate longer spans.

Until recently, this technique was limited to use for straight concrete I-girder sections. With the introduction of new concrete casting technology and construction techniques, spliced U-girder technologies now allow the option of curved bridges.

One example of this technology and technique in use is the complete redesign of the interchange between I and S.

The project owner, the Florida Department of Transportation FDOTfound it was best to implement this new spliced U-girder technology due to the time and cost savings seen in other projects that implemented it.

FDOT found it best to use new spliced U-girder technology for the sake of time and cost savings on the project. I carries the flow of north and south traffic through the heart of Jacksonville, while JT Butler Blvd. This project consisted of four total bridge structures, new ramp configurations, new highway alignments and roadway widening of both I and S.

Summit, which is headquartered in Colorado, has implemented spliced precast girder technology on numerous constructed bridges. The main goal of the project was to ease traffic congestion at this major interchange. Flyover 1, the main bridge of the project, is a new ramp designed to alleviate the traffic jams and traffic safety issues caused by the previous configuration.

Unfortunately, during peak travel times, traffic would back up onto I for up to a mile, creating long commute times and safety issues for the traveling public. The new Flyover 1 bridge is a seven-span, 1,ft-long structure.

The bridge will help to provide a continuous flow of traffic, allowing for a direct merge without stopping. Only overnight lane closures were allowed, providing six- to eight-hour windows for all the construction and erection procedures that needed to occur in traffic areas.

In order to facilitate construction, the maintenance of traffic MOT plan was integral to the success of the project. Therefore, several traffic shifts were executed to open different areas of the project site for construction while maintaining all of the travel lanes as required by FDOT.

To accommodate the constant flow of traffic through the jobsite, several innovative features were incorporated into the bridge design. For this project, precast pier caps were deployed at the interior piers. These locations were adjacent to traffic during construction, which meant using temporary shoring to support the formwork was not an option. These pier caps were cast by the contractor on-site with a central blockout to form a cast-in-place CIP connection with the column.

The precast pier caps also were used to support the pier girders during construction, helping to eliminate the need for falsework towers within the traffic zone. The pier girders were erected onto temporary falsework towers at one end and supported on the precast pier caps with large cantilevers. Due to the geometry of the site and the active traffic lanes, minimizing the amount of falsework towers was a key component in the design of the Flyover 1 bridge.

The cantilevered pier girders supported drop-in girders on strongbacks, thus eliminating the need for falsework towers at these locations. The strongbacks connected to the girders through a partial-depth diaphragm, supporting them from the top. This strongback configuration allowed the team to supply the minimum vertical clearance over traffic since there was no hardware from the strongbacks projecting below the bottom surface of the girders.

Span 6 of the Flyover 1 bridge is the second-longest span in the structure, measuring Girder shipping weights limit the maximum piece length to ft for pier girders and ft for drop-in girders. Due to the pier locations and site geometry, a single drop-in girder could not span between pier girders. To overcome this geometric constraint, a temporary straddle bent was designed to support two drop-in girders at the central splice location in this span. The straddle bent spanned approximately 70 ft to provide clearance for three traffic lanes.

Some of the temporary works for the project, while out of traffic lanes, were still within the envelope requiring crash protection.LiftingSafety offer online a massive selection of lifting clamps to cover all user applications.
