Washington Gantry - Mounted Revolving Crane (250 Ton)

Seller Description

 This Washington Gantry-Mounted 250 Ton Revolving Crane ­­­­­is no longer needed for company's own operation and is being sold as an asset liquidation for its owner.

PURPOSE OF MACHINE

This "WASHINGTON" gantry-mounted, full-revolving crane was engineered, designed and manufactured by Washington Iron Works, Division of Formac International, Inc., to provide the most efficient means of handling general shipyard work. This heavy-duty constructed crane is capable of hoisting, revolving, and traveling with loads up to 250 tons. Ultra-responsive controls allow safe and accurate spotting of these loads.   The whip hook is capable of hoisting loads up to 25 tons at speeds nearly ten times as fast as the main hook.   The hoist controls feature fast light-hook-capabilities which allow hoisting light loads at higher than rated full load speeds. These major characteristics, in addition to having been designed in accordance with all possible American standards and specifications applicable, result in a crane designed to its maximum capabilities.

This "WASHINGTON" crane, like one of the over 430 others designed and built by Washington Iron Works since 1940, will prove capable of providing safe, dependable and profitable service.

DESCRIPTION

GENERAL.

This  "WASHINGTON" gantry-mounted revolving crane consists of a four-sided gantry tower which is mounted on eight wheels per corner. Four wheels' at each corner are powered for crane movement on the revolving superstructure, which consists of a machinery deck and houses counterweight, operator's cab, A-frame, boom and all load tackle.   The crane stands approximately 325 feet high with the boom at minimum radius.   Total weight of the crane, including counterweight, is approximately 1,300 tons.   Vertical movement of the load is through the hoist systems; horizontal movement is by slewing: and gantry travel.   The machinery house provides an enclosed area for a two-drum hoist unit, Tufting hoist unit, two swinger units, electrical control panels and pneumatic control components.   The crane is furnished with a 250-ton capacity sister-hook block for the eighteen-part main line, and the two-part whip line is equipped with a 25-ton capacity hook block.

POWER.

All crane motions are accomplished electrically through P&H Harnischfeger D.  C. drives. 460 volt, 300 H.P. motors, coupled to-.Jeffrey gear reducers, provide power for both hoist units.  Gantry travel is accomplished by two 240, VoTt, 25 H.P. motors last each leg. Each motor transmits power through- a Cone Drive reducer which, in turn, drives two wheels.- Twin slew. units, each powered by a 500 volt, 100HP motor,  provide adequate power for crane rotational movement. Power for all operations is generated by a Detroit Diesel 12V149 engine driving a Marathon 600 K.W., alternator located on the gantry platform.

CONTROLS.

The controls for all crane movements are located in the operator's cab. Controls for normal operation are an integral part of the operator's chair. This arrangement has proven more efficient and convenient for operator operation. 

The master switches were furnished by P&H Harnischfeger and feature "stepless" operation and nonspring returning,  "dead man" control levers,   The latter feature allows a skilled operator to hoist, slew and travel simultaneously.
The hoist controls include controlled acceleration and deceleration, dynamic braking, a slow-speed point when lowering loads lighter than the maximum rated load for more convenient and accurate spotting and a high-speed, light hook feature when hoisting loads lighter than the maximum rated load.   Drum brakes are the fail-safe type and are spring-set with air or electrical failure as well as being normally operator controlled.   The swing and gantry controls feature adjustable acceleration and deceleration rate control with reversing-plugging operation and dynamic braking.
