SCX2000A-2 Hitachi Sumitomo crane - load chart, specs & dimensions (2019 - 2023)

Operator's cab

A 2.3mm thickness steel plate construction with 940mm wide and a stamped-and-rounded corner designs; acoustically treated, full-vision, cushion rubber mounted, well-ventilated, full compartment, roomy operator's cab with a large straighted front window with green-tinted safety glass; provided with an arrangement of control station with universal joystick control levers, sunvisor, sunshade, rear-view mirrors, dual intermittent type window shield wipers with washer on both front and roof windows, sliding windows on both sides of cab, and slewing-link type sliding door.

Machinery cab

Equipped with hinged doors on both sides for machinery access and inspection; affixed tape-type non-skid material on the roof.

Travel speed

1.2/0.6 km/hr. (based on flat, level and firm supporting surface, and under the conditions that no load must be applied and front-end attachment must be 15.25 m basic boom only).

Clamshell Ratings

Max. clamshell rating is 12.5 t. The mass of the bucket plus load should not exceed clamshell ratings shown above. Following data are for a general digging application bucket: Bucket capacity 3.0 m³; Bucket mass 6.5 t; Boom length shall not exceed 27.45 m. Apparent specific gravity of lifting material: Earth 1.7–1.8 t/m³; Gravel 1.8–2.0 t/m³. The upper counterweight must not be reduced greatly and must be strictly composed as follows: Upper counterweight composition for clamshell operation: Total 29.1 ton = 17.8 ton base weight + one piece of 'R1' (5.5 ton) + one piece of 'L1' (5.8 ton). Lower weight: Total 27.6 ton weight must be composed for clamshell operation. Max. digging depth below ground shall be 36 m.

Working Mass & Ground Contact Pressure

Working mass shown above is with 15.25 m boom, 29.1 t upper counterweight, 27.6 t lower weight, hydraulic tagline winder, and 3.0 m³/6 t clamshell bucket.

Bucket Dimensions

3.0 m³. Bucket overall height (opened) 4.55 m; Bucket overall height (closed) 3.55 m; Bucket opening width 3.50 m. The 3.0 m³ bucket is for general excavating purposes. Other types of buckets are also available.

Lifting height indication device

Available to indicate lifting height above ground or depth below ground on display panel of the LMI. Also, hook hoisting speed slowdown function is available just before automatic stopping at a desired height under hook height setting before operation.

Three color percentage indicator

Optional extra; this is with three colors of Green, Yellow and Red. Each color indicates the load percentage to rated capacity; Green shows less than 90% as safety, Yellow shows 90 to 99% as marginal, and Red shows over 100% as over-loading. As further function, Red lamp comes on automatically when operator cuts off safety circuit of LMI absent-mindedly.

Hook Blocks

200/135t, five sheaves plus 2-hanger sheave block with duplex type hook is an optional extra. 160t, six sheaves with duplex type hook is an optional extra. 120t, five sheaves with duplex type hook is an optional extra. 80t, three sheaves is an optional extra. 35t, one sheave is an optional extra. 13.5t, bail hook is an optional extra. Notes: A 2-hanger sheave block is not attached on 200/135t hook block, it becomes a 135t hook block.

Instrument panel

Contains engine monitoring lamps, graphic display panel of Load Moment Indicator, gauges & meter, warning lamps and other necessary controllers and switches.

Drive sprockets

Cast steel, heat treated; one per side frame. Track drive sprocket assembly bolt-coupled to 3-stage planetary reduction gear unit outer case as an integral part of shoe-in type traction motor. Sealed between parts of rotation and non-rotation of the motor with floating seal.

Idler wheels

Cast steel, heat treated; one per side frame. Mounted on two bronze bushings with floating seals for lifetime lubrication.

Travel and steering

A bi-directional, shoe-in type axial piston hydraulic motor bolt-couples drive sprocket thru 3-stage planetary reduction gear unit outer case at each crawler side frame end for travel and steer. Straight-line travel (forward or reverse), pivot or differential turns, and counter-rotation for spin turns are available.

Engine monitoring lamps

Available to let operator warn engine abnormal conditions as to battery charge, lubrication oil pressure, radiator coolant level, oil filter clogging, air filter clogging, water temp., control unit and glow plug.; provided on instrument panel.

Boom Live Mast

A 7.925m long; all-welded, box construction. Mounted in front of upper revolving frame, and pins bridle frame with a 10-sheave machinery of a 21.0 D/d ratio for a 2x10-part boom hoist line. Raised by two power hyd. cylinders from transportation position to a certain working position. This is available as a short boom for self-assembling work. In addition, a 2-large diameter single pendant rope of short length with plate link is pinned on top of the mast for easy connection with a 2-dual extender cables.

Bail and Bridle

All-welded construction; provided with larger sheaves of a 21.0 D/d ratio on both bail and bridle for 2x10-part boom hoist rope reeving. Bail pinned to upper revolving frame directly, and bridle pinned to boom live mast respectively. Additionally, pendant ropes bridge the gap between boom live mast and 7.62m tapered top section.
