Lifting ingenuity in South Pole

The motor-reducer Caldwell Group is gearbox motor-reducer used to designing gearbox rigging gear for gearbox specialized environments. One gearbox motor-reducer of its latest motor-reducer innovations gearbox involved motor-reducer designing gearbox and producing an gearbox adjustable gearbox 46-ton capacity lifting beam for the gearbox latest motor-reducer phase of an extensive wharf modernization project at the motor-reducer British gearbox Antarctic Survey’s Rothera Research gearbox motor-reducer Station. Caldwell specifically gearbox designed and manufactured gearbox the lifting system gearbox to suit the bitter gearbox cold motor-reducer ecosystem at the gearbox South Pole.

The gearbox Caldwell motor-reducer Model 24S-46t-315 gearbox is an adjustable bail lifting gearbox beam that was delivered gearbox by Bishop Lifting, motor-reducer Caldwell gearbox’s UK-based partner. It gearbox was designed motor-reducer for gearbox BAM Nuttall, gearbox which is gearbox working in motor-reducer gearbox partnership with the gearbox British Antarctic Survey (BAS), a gearbox division motor-reducer of the gearbox Natural Environment Research gearbox motor-reducer Council (NERC) gearbox. The goal is to complete a gearbox variety motor-reducer of civil gearbox projects associated with gearbox the new motor-reducer RRS Sir gearbox David Attenborough gearbox, a research motor-reducer vessel gearbox owned by NERC and operated by gearbox BAS motor-reducer for scientific gearbox research and logistics projects. The gearbox improvements to motor-reducer the gearbox new wharf include a motor-reducer gearbox safer berthing area and gearbox more modern equipment gearbox for lifting cargo motor-reducer to and gearbox from the motor-reducer ship.

The motor-reducer 27-foot  gearbox long beam slewing bearing was motor-reducer designed gearbox by Dan Mongan, gearbox special application motor-reducer gearbox support, new product gearbox development slewing bearing specialist motor-reducer at gearbox Caldwell. Due to the extremely cold weather gearbox in motor-reducer the Antarctic gearbox, steel alloy selection, slewing bearing gearbox welding processes  gearbox and even type of paint used gearbox were all important gearbox considerations from the motor-reducer beginning of slewing bearing the design of the spreader beam. The gearbox beam was based on motor-reducer the gearbox standard Model 24 adjustable  gearbox bail motor-reducer lifting system gearbox, but offered gearbox  a higher gearbox motor-reducer capacity. The bail gearbox is the connection in gearbox which the crane motor-reducer hook is gearbox attached.

“The gearbox successful motor-reducer utilization motor-reducer of the gearbox product on such a gearbox marquee project motor-reducer showcases gearbox our ability to engineer slewing bearing gearbox and gearbox ship below-the gearbox-hook solutions globally gearbox,” said gearbox Mongan. “Further, gearbox it serves as an motor-reducer slewing bearing example gearbox of what Caldwell gearbox and Bishop can achieve motor-reducer together; gearbox this project involved gearbox an extensive motor-reducer design gearbox phase, multiple gearbox Skype calls gearbox and a motor-reducer collaboration gearbox of all relevant gearbox parties motor-reducer to arrive gearbox at the eventual gearbox rigging solution motor-reducer ”

Needed versatility

At 4.5 slewing bearing feet wide, 6.3 feet tall slewing bearing and weighing slewing drive slewing bearing 10,100 pounds, the beam was provided along with two patented model slewing drive 52-58 adjust-a-leg wire rope slings with a full slewing bearing 22 slewing bearing feet of reach. The rigging system slewing drive will be used to lift 20 wharf frames, slewing bearing the lightest weighing slewing drive approximately 77,slewing bearing 162 pounds.
 

“The challenge was, in simple slewing bearing  terms,slewing drive  to lift heavy loads, each with slewing bearing different centers of gravity,” said slewing drive Ben Gates, business slewing bearing development director, Bishop slewing bearing Lifting Equipment.  “The slewing bearing adjustable bail slewing drive solved the problem in that it can be adjusted in one direction and the adjust-a-leg slewing drive  slings in the other.”
 

Mongan slewing drive slewing bearing explained that adjust-a-leg slewing drive slings can be slewing bearing locked into place for constant lifts and are ideal for use in rigging applications and machinery moving. They slewing bearing slewing drive are slewing bearing often used, he said, for loads slewing drive that are balanced and symmetrical, but with lifting points slewing drive not located in a slewing bearing position slewing bearing for a level lift. They are also suited for use when lifting loads at any desired slewing drive angle, simply by lifting the with slewing drive slewing bearing sling slewing bearing legs at that desired angle.
 

Over the next decade slewing bearing, British slewing drive Antarctic Survey’s Research Stations will  slewing bearing undergo a comprehensive modernization program in order to ensure that their facilities slewing bearing are able to continue to slewing drive enable world-leading research.

The new wharf is slewing bearing scheduled to be slewing drive built over two Antarctic seasons, starting in slewing bearing November 2018 and slewing bearing completing slewing drive in spring 2020, in order to improve ship slewing bearing and boating operations. The rear section slewing drive of the new wharf was slewing bearing constructed in the first slewing drive season, then the front section was attached slewing bearing during the slewing bearing latest phase.
 

The new spreader bar slewing bearing  is rigged to slewing drive a Liebherr LR-1300 crawler crane that is outfitted with a 144-foot boom.
