Introduction
General
The RAPIER W700E is an electric walking dragline built to a modular design which facilitates dismantling, highway transport and rC3-erection when changing si tes.
The machine consists basically of a base and a rotate frame with hoist, drag and swing gear, walk mechanism, boom and bucket.
BASE
The base is a circular structure which provides the machine with a large loadbear ing surface. The base centre post is the axis of the rotate frame and transmits the drag force to the base when digging.
ROTATE FRAME
The rotate frame, which carries the boom, machinery and operator1s cab, is supported on a roller ring assembly 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 converter, transmission gearbox, and the drum gears and clutches.
A dog-clutch on thehoist drum shaft transmits the drive to the walk shaft (when operating in the WALK mode) via a train 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 modul ated cl utch, providing the operatQr with a precise and continuously variable control of speed.
The d. c. generator powers the two reversible swing motors which drive the swing pinions via reduction gearboxes. The swing pinions engage a circular rack on the machine base and so impart swing motion to the rotate frame. Con.trol circuitry provides the operator with precise and continuously variable control of swing speed in either direction, while dynamic braking brings the rotate frame rap idl y to rest when the operator's control is returned to neutral.
A transformer provides a 3-phase supply for the cooling fan motors, pumps, etc; a single phase supply, derived from this 3-phase supply, energizes the a. c. control circuits.
BOOMS, BUCKETS
ro I A choice of three boom lengths is available and the machine can be rigged for any one of three boom angles. A choice of bucket sizes is also available, depending > on boom length and angle.
THE OPERATORS MANUAL
This Manual c;omprises four Parts, preceded by a Machine Data section and followed by an Alphabetical Index.
The Machine Data section relates to an individual machine, specified by the Machine Number and the Customer's Name. It provides working data and an abridged specification, recommended lubricants, etc. At the end is a list of Publ ications, produced by the Suppl iers 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 th is Manual are general, cover ing 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.
Part 3 covers rope handl ing and install ation.
Part 4 covers preventive ma intenance and includes a routine ma intenance ' schedule and details of the various lubrication and adjustment procedures. Technical information on the compressed air, electrical and automatic lubrication 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 contents of the Manual.
At the end of this Manual, prOVISion is made 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 operate the machine. Precautions detailed throughout the Manual must be strictly observed.
OPERATING WITHIN MANUFACTURER'S LIMITS
It is the responsibility of the operator to ensure that the machine is operated within the Manufacturerls limits; on no account should the specified maximum digging depth, dump height or suspended load be exceeded.
CHANGING BOOM ANGLE
When changing the boom angle, it is essential for the boom to be properly supported on suitable blocks or trestles when lowered to the horizontal.
DANGER FROM OVERHEAD ELECTRIC LINES
The following safety precautions must be strictly observed. Regard every overhead I ine as being elec trically 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 shoul d al so be remembered that a dangerous condition can arise even when the boom is several feet away from the overhead line.
Where digging or dumping must be carried out in close proximity to overhead electric I ines, take spec.ial care to ascertain the height and distance of the overhead lines. Remember that it is difficult to estimate the he ight of I ines by normal methods of observation.
DANGER FROM ASBESTOS DUST
Clutches and brakes should be cleaned either by vacuum cleaning or by wiping 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 floor should be removed by vacuum cleaning or, alternatively, damped thoroughly before being swept up and placed in dustproof bags for disposal.
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.
