 HIGH OUTPUT ENGINE

 If you want to carry out more work and you

have the choice between two machines of more or less the same performance,

remember that power makes the difference The engine on the PC1250 is the highest in its class: it is 29 kW (39 HP) larger than on the current machine and 7

kW (9 HP) larger than Hitachi EX1200

 Air-cooled after cooler

 An air-cooled after cooler with excellent cooling efficiency is used

By reducing the temperature of the air supply, it has become possible to realize high output while reducing NOx

 2-WORKING MODES (A·E)

 Active mode (A mode) supplies maximum engine power

resulting in high levels of production

 Economy mode (E mode) improves fuel consumption

POWER TRAIN

 LARGE BUCKET CAPACITY

(LARGEST IN ITS CLASS)

 Increasing the weight of

the machine and moving

the center of gravity to the

rear has made it possible

to increase the bucket

capacity by 4%, which

gives this machine the

largest bucket capacity in

its class

 Machine weight increased

 The weight of the

machine has been

increased approx 4

tons (4.8 U.S tons)

 Improvement in machine stability

 The weight of the counterweight has

been increased from 17.4 tons (19.2 U.S

tons) to 18.0 tons (19.8 U.S tons)

 Approx 3 tons added to frames –

revolving and track frame

 Heavier castings designed for work

equipment

STRUCTURES

 The engine meets Tier 2 emission regulations in USA,

Europe and Japan.

Tier 2 emission regulations

 The quantity of NOx and PM (Particulate) must be the following

values or below

PC1250-7’s discharge amount of NOx and PM are reduced by 35% and 63%compared with that of PC1100-6 respectively

POWER TRAIN

 The noise level around the machine

becomes highest at 15 m on the right side

of the machine The noise level of PC1250

at this point is 3 dB(A) lower than that of PC1100 (The sound energy is reduced by 50%.)

 Low-noise design to lower working noise for environment

 If the low-noise sound absorbing duct for

Europe is installed, the noise level is lowered below 80 dB(A)

STRUCTURES

 Strengthening of boom

 The basic strength of the boom was increased when PC1000 was

model-changed into PC1100 Keeping this strength, the boom of PC1250 is farther improved

STRUCTURES

 Strengthening of arm

 The basic strength of the arm was increased when PC1000 was

model-changed into PC1100 Keeping this strength, the arm of PC1250 is farther improved

STRUCTURES

 Strengthened bucket with wear-resistant plates and shrouds

1 Quarries, sand and gravel, mining

 This bucket is used to load blasted rocks in heavy rock

applications of all types

 The side plates and bottom plates are thickened to increase the

rigidity of the whole bucket

STRUCTURES

2 Highly abrasive rock applications

 This bucket is used in quarries where the bucket wears quickly

The wear resistance of its bottom corners is increased

STRUCTURES

 Strengthening of revolving frame

STRUCTURES

 Strengthening of swing circle

STRUCTURES

 Change of shape of travel piping cover

 The shape of the travel piping cover is changed to protect the

piping from flying rocks and increase the reliability and durability of the travel unit
