Specifications

UPPER REVOLVING FRAME:All-welded, precision machined, robustconstruction. A machined surface providedfor mounting load hoist and boom hoistassemblies, and mounting itself on turntablebearing. And pins bail frame with a 12-sheave machinery and single center sheaveof a 21.0 D/d ratio for 2×12-part boom hoistreeving.

TURNTABLE BEARING WITH INTERNAL SWING GEAR:Heavy duty, single shear ball type; inner raceof turntable bearing with integral, internalswing (ring) gear bolted to carbody frame,and outer race of turntable bearing bolted toupper revolving frame.

CONTROL SYSTEM:System contains two sets of triplicate tandemvalves which direct oil to various machinefunction and are actuated by control levers viaremote controlled hydraulic servo for allmotions. Working speeds can be preciselycontrolled by motorcycle type throttle andpilot-operated arm chair single axis controllevers in cooperation with “EPC” controllerthat varies engine rpm and hyd. pumpdischarge simultaneously, or varies just hyd.pump discharge while keeping engine rpm viamotorcycle type grip throttle. System alsotakes a specially-tailored unique hydrauliccircuit to maximizes drum horsepower, andreduces horsepower loss with eliminating thepossibility of engine stall.

Pump control system — By “EPC” controller thatprovides two modes of engine-pump control.MODE I:The “EPC” Controller is normally programmedto vary the engine speed and pump dischargesimultaneously. Simply twisting the gripadvances the engine to maximum speed andthe hydraulic pumps to maximum flow at thesame time. This mode is suitable to precisioncrane work.MODE II:By activating a switch, it is able to vary justthe pump discharge by means of the gripthrottle, while keeping engine speed fixed.Mode II is convenient for operations such aslifting magnet and bucket work, where theengine is normally run at full throttle.

Notes — Liftcrane capacities1. Capacities included in these charts are the maximum

allowable, and are based on machine standing level on firmsupporting surface under ideal job conditions.

2. Capacities are in metric tons, and are rated in accordancewith European EN13000 Standards in terms of machinestability and structural strength limitations; the figuressurrounded by bold lines are based on factors other thanthose which would cause a tipping condition.

3.Capacities are based on freely suspended loads and make noallowance for such factors as the effect of wind, suddenstopping of loads, supporting surface conditions, and operatingspeeds. Operator must reduce load ratings to take suchconditions into account. Deduction from rated capacities mustbe made for weight of hook block, weighted ball/hook, sling,spreader bar, or other suspended gear.Hook block weight is as follows:275t...........4.3ton 250t ..........3.7ton145t...........3.3ton (275t use)145t...........2.7ton (250t use)80t.............1.4ton 35t ............0.9ton 13.5t ........0.6ton

4. All capacities are rated for 360° swing.5. Least stable rated condition is over the side.6. An 102.8ton counterweight and 18.0ton carbody weight are

required for all capacities on this chart.7. Attachment must be erected and lowered over the ends of

the crawler mounting.8. Main boom length must not exceed 91.45m.

Maximum fly jib length permitted — 36.55m.Maximum boom plus fly jib combination length permitted —70.1m+36.55m.Maximum boom length when mounting auxiliary short jib is88.40m.

9. Capacities when handling load off main boom head sheavesin case of mounting fly jib or auxiliary short jib on top ofboom are detailed; if required, please consult us or nearestdistributor.

10. Boom combination shall be in accordance withmanufacturer’s standard described here in “BoomCombination Diagram” of page 16.

SCX2800-2 AUXILIARY SHORT JIB CAPACITIES:Max. 13.5ton

Note: Jib capacities is almost equal to the figures made by thededuction of apporx. 600kg from the liftcrane capacities forboom length up to 88.40m unless restricted by themaximum jib capacity shown above. As to the details,please consult us or nearest distributor.

Notes — Fly jib capacities1. Capacities included in these charts are the maximum

allowable, and are based on machine standing level on firmsupporting surface under ideal job conditions.

2. Capacities are in metric tons, and are rated in accordancewith European EN13000 Standards in terme of machinestability and structural strength limitations; the figuressurrounded by bold lines are based on factors other thanthose which would cause a tipping condition.

3.Capacities are based on freely suspended loads and make noallowance for such factors as the effect of wind, suddenstopping of loads, supporting surface conditions, and operatingspeeds. Operator must reduce load ratings to take suchconditions into account. Deduction from rated capacities mustbe made for weight of hook block, weighted ball/hook, sling,spreader bar, or other suspended gear.Hook block weight is as follows:35t.............0.9ton 13.5t .........0.6ton

4. All capacities are rated for 360° swing.5. Least stable rated condition is over the side.6. An 102.8ton counterweight and 18.0ton carbody weight are

required for all capacities on these charts.7. Attachment must be erected and lowered over the ends of

the crawler mounting.8. Maximum fly jib length permitted — 36.55m.

Maximum boom plus fly jib combination length permitted —70.1m+36.55m.

9. Capacities when handling load off main boom head sheavesin case of mounting fly jibon top of boom are detailed; ifrequired, please consult us or nearest distributor.
