640HD Specification Sheet

Diesel engine
Caterpillar diesel engine C-7 Acert - Tier III, water-cooled, 168 kW (225 HP) / 2000 rpm
   
Optional:
Caterpillar diesel engine C-9 Acert - Tier III, water-cooled, 205 kW ( 278 HP) / 2000 rpm
 
Dry air filter with main and safety element. Electric system 24 Volt, high efficiency cold starting batteries.
Idling speed function.
 
Fuel tank capacity approx. 450 l
Hydraulic system
All hydraulic pumps are variable displacement piston pumps with individual regulation for each pump. The pumps are equipped with an energy-saving flow-on-demand control system and pressure cut-off for high efficiency and reduced loss of energy.
Max. flow rates:
320 l/min for travel and winch 1
320 l/min for travel and winch 2
220 l/min for swing and boom hoist Working pressure up to 330 bar. Hydraulic tank capacity approx. 650 l
 
Optional:
Additional hydraulic packages for external user
(e.g. casing machines, vibrators, etc.)
Hydraulic oil filter with long intervals between change. Large dimensioned
hydraulic cooling system. Servo-assisted joy-stick controls according to ISO-System. Central service tableau. Decomposable hydraulic oil (synthetic) can be used.
Hydro Clean hydraulic superfine filter with water absorption (optional).
Swing drive
The swing function is independent operated through 1 swing drive with hydraulic piston motor and oil bath planetary gear.  Spring-loaded hydraulically releasable multiple-disc brake, self-closing. Swing speed from 0 to 3.7 rpm, 0 to 1 rpm for crane operation.
Precision swing operation with preselector switch. Large dimensioned swing bearing, external gears thus less tooth pressure and moments.

 

Upper structure
Torsion-free precision machined upper frame.  All components are located clearly and service friendly. Engine installation very service-friendly in longitudinal direction with low noise level.
 
Counterweight 12.5 t
Boom Hoist Operation
Independent operation via axial piston motor, spring-loaded hydraulically releasable multiple-disc brake, planetary gear and winch drum with special scores. Max. line pull 52 kN (5.3 t).
Drum pawl lock provides an integral drum lock
Winch 1 - Winch 2
Each winch is driven independently by a directly flanged hydraulic piston motor. Hydraulic brake valves for wear resistant braking of loads. Strong low maintenance oil bath planetary gears. The clutch and brake functions are effected through
large dimensioned, maintenance-free, low-wearing, oil-lubricated multiple disc brakes.
Grab closing automatics for 2 rope grab operation - dividing the load equally between both winches.  Combilink - for dragline operation, allows power loadlowering for the dredging winch.
 
Winches                                      12 t       16 t
Single line pull kN 1.Layer       120        160
Rope dia. mm                            22         26
Line speed m/min                     70/126   60/116
 
Optional: Additional crane winch

Complete crane safety device with electronic  SLI- safe load indicator.
Undercarriage
Strong hydraulically extendable crawler undercar- riage. Each track is independently driven by an axial piston motor through planetary final drive.
Spring loaded hydraulically releasable multiple-disc brake.
Maintenance-free tractor type crawler with hydraulic track-tensioning device. Tractor type crawler with triple bar shoes. Excellent rough terrain travel.
