Long boom Long Reach is the hinged equipment of a special purpose that is used for the production of works in hard to reach places situated at a considerable distance from the excavator.

Applications:

  • The construction of the subway, ports
  • The layout is tight earthen: slopes of roads, slopes, ponds and rivers
  • Cleaning of rivers and water bodies from clay, silt, etc.
  • Dredging

The main advantage of the shovels with long shafts Long Reach – increased range of work.

The size of the boom and stick of an elongated equipment significantly exceeds the standard samples. Reach and digging depth , long Reach boom Long can exceed the standard indicators arrows more than 50%, thus allowing you to maximise results and thus to save time and money.

There are different sizes of shafts Long Reach for almost all brands of excavators. The most popular extra-Long Reach boom for excavators KOМATSU, VOLVO, CATERPILLAR, HITACHI is represented on the website TORION.

It is important to be aware of the features of long arrows Long Reach – low pressure force handle, the lowest the digging force of the excavator and a small volume of the bucket.

In the selection of a long boom Long Reach we need to consider the recommendations of the manufacturer. Each excavator has certain specifications and allowable standards used equipment, which allows to ensure stable operation of the equipment.

Without additional calculations and modifications are not desirable, the excess volume of the bucket, set by the manufacturer, as this entails the risk of losing the security and stability of the car.

Recommended bucket volume of 15-16 m. arrows:

VOLVO EC210 – 0.52 m3

HITACHI ZX200 – 0.45 m3

KOMATSU PC210 – $ 0.49 m3 up to 0.66 m3

Recommended bucket capacity 18 m boom:

CATERPILLAR 320D – from 0.44 m3 to 1.13 m(excavating bucket, without quick coupler)

VOLVO EC300 – 0,57 m3

HITACHI ZX330 – 0.52 m3

KOMATSU PC240 – 0,27 m3 to 0.38 m3

Recommended bucket capacity 22 m. jib:

HITACHI ZX330 – 0.40 m3

KOMATSU PC360 – from 0.47 m3 to 0.63 m3

After you have selected a suitable Long Reach boom, there comes the final stage of installation and use. Here is a very important organization and approach to the work itself.

Before installing the boom Long Reach, one of the first, the question arises: “to use the quick coupler or not?”. The quick couplers manufactured by quick couplers useful in the work, but because usually they weigh 400-500 kg, however, significantly affect the capacity of the machine. Due to the fact that when you work with extended boom Long Reach weight is very critical, sometimes you have to abandon the quick couplers manufactured by.

To install the long boom Long Reach will require using a 6 ton crane.

Step 1. To place the excavator on a flat surface, prepare a crane and other tools.

Step 2. Standard equipment: bucket, boom, arm, cylinder arm, etc.

Step 3. To raise the long boom Long Reach with a crane, use the arrow pins for fixation.

Step 4. Connect the hydraulic cylinder of the boom Long Reach to the hydraulic system of the excavator.

Step 5. Connect the other end of the hydraulic cylinder to the boom Long Reach.

Step 6Install the cylinder arm

Step 7. Put the boom Long Reach as shown in the figure below. Install the handle on 2 of the wooden box, connect the bucket cylinder.

Step 8. First attach the handle to the boom Long Reach, then the other end of the cylinder arm to the hilt.

Step 9. To raise stick boom Long Reach, set the bucket.

Excavator is ready to work.

In achieving success, undoubtedly, an important role is the operator of the excavator. To work with extended working equipment Long Reach, the operator should have a wealth of experience and a lot of patience. The longer the arrow, the more experienced and patient should be the operator since he need to take into account the dynamics of the machine with the long boom Long Reach; more attention is required by the end of the boom, its the speed of rotation of the swing.

Good preparation, taking into account all subtleties of work with extended working equipment Long Reach, will undoubtedly bring excellent results.
