General

The RAPIER W700E is an electric walking dragline bUilt to a modular design w.hich facilitates dismantling, highway transport and re-erection when changing sites.

The machine consists basically of a base and a rotate frame with hoist, drag and swing gear, walk mechanism, boom :md bucket.

BASE

The base is a circular which provides the machine with a large loadbear ing surface. The base centre post is the ax is of the rotate frame and transmits the drag force to the base wher digging.

ROTATE FRAME

The rotate frame, wh i ch carri es the boom, mach inery and operator IS cab lis supported on a ro II er ring assembl y on the base.

DRIVES

The machine is powered by a motor-generator set.

The motor drives the hoist and drag drums (when operating in the DIG mode) via a torque conve'rter, transmission gearbox, and the drum gears and clutches.

A dog-clutch on the hoist drum shaft transmits the drive to the walk shaft (when opef-ating in the WALK mode). via a :rain of gears; eccentrics at each end of the walk shaft impart the walk motion to the two walk legs and shoes.

The torque converter incorporates a modulated clutch,providing the operator with a precise and continuously var 'able control of speed.

The d. c. generator powers the two reversible swing motors which dr.ive the sw ing p in ions via reduct ion gearbo>-:es. The sw ing p in ions engage a ci rcul ar rack on the machine base and so impart swing motion to the rotate frame. Control circuitry provides the operator with precise and continuously variable control of swing speed in either direction, while dynamic braking brings the rotate frame rapidly to rest when the operator1scontrol is returned to neutral.

A transformer provi des a 3-phase supp Iy for the coo I ing fan motors I pumps I etc; a single phase supply, derived from this 3-phase supply, energizes the a. c. control circuits.

BOOMS, BUCKETS

A cho ice of three boom I engths is ava iI abl e an d the mach ine can be rigged for any one of three angles. A choice of bucket sizes is also available, depending ""') > on boom length and angle.

THE OPERATORS MANUAL

i-his Manual c;omprises four Parts, preceded by a Machine Data section and followed by an Alphabetical index.

The Machine Data section relates to an iindividual machine specified by the Machine Number and the Customer1s Name. It provides data and an specification, recommended lubricants, etc. At the end is aI ist of Publications, produced by the Suppliers of certain pieces of incorporated equipment, which are referred to in the main text. Copies of these Publ ications are suppl ied with the machine.

Parts 1- 5 of this Manual are general, covering all the standard variations of boom length, boom angle, bucket capacity, etc.

Part 1 gives a general decription of the machine, power flow diagrams and brief details of the compressed air, electrical and automatic lubrication systems.

Part 2 describes the various controls and instruments, start-up, shut-down and emergency procedures, and how to operate the machine.

,.)art 3 covers rope handl ing and install Etion.

Part 4 covers preventive ma intenance and includes a routine ma intenance schedul e and deta iIs of the var ious I ubr' cation and adjustment procedures. Techn i cal information on the compressed air, el ectr icaL and automa t ic I ubr ication systems is also included in this section to facil itate faul t-finding.

Part 5 covers the boom angle variations and the boom hoist systems.

The comprehensive Alphabetical Index provides a useful reference to the whole of the Manual.

At the end of this Manual, prOViSion is nade for the insertion of Appendices to cover changes in design, special customer requirements, etc, which may occur subsequent to the publ ication of this issue.

Safety

WARNING TO OPERATORS AND MAINTENANCE PERSONNEL

This Operators Manual is intended for the guidance of operators and individuals responsible for the maintenance of this machine. It is essential that operators famil,iarize themselves with the controls and operating techniques before making any attempt to opera te the mach ine. Precautions deta iI ed throughout the Manual must be strictly observed.

OPERATING WITHIN MANUFACTURER'S LIMITS

It is the responsibility of the operator t:J ensure that the machine is operated within the Manufacturer's limits; on no account should the specified maximum digging"depth, dump height or suspended load be exceeded.

CHANGING BOOM ANGLE

lJIJhen changing boom angle, it is essential for the boom to be properly -supported on suitable blocks or when lower'ed to the horizontal.

DANGER FROM OVERHEAD ELECTRIC LINES

The following safety precautions must be strictly observed. Regard every overlhead I ine as be ing eI ectrically charged unless you have it in writing from the Electricity Authority that it is not.

Extreme care must be taken when the machine has to operate near overhead lines which cannot be made dead, since inadvertent rotation of the boom may introduce danger. It should also be remembered that a dangerous condinon can arise even when the boom is severa I feet away from the overhead line.

Where digging or dump ing must be carried out in close proximity to overhead electric I ines, take special care to ascertain the height and distance of the overhead lines. Remember that it is difficult to estimate the he i gh t of lines by norma I me thods of observat ion.

DANGER FROM ASBESTOS DUST

Clutches and brakes shou Id be cl eaned either by vacuum cleaning or by wip ing with a damp cloth. Cleaning by compressed air or with a dry brush must be avoided. Any dust or particles which may have accumulated on the workbench or fioor should be removed by vacuum cleaning or, alternatively, damped thorough Iy before be ing swept up and pI aced in dustproof bags for di sposal.

WELDING PRECAUTIONS

The earth electrode must be connected directly to the item being welded to local ize the welding current and so prevent damage to other parts of the machine.
