Long Reach Excavators For Sale

Long reach excavators have been around for a while and are a further development of the original excavator which is believed to have been invented in 1835 in Massachusetts by William Otis.  The development of excavators has been ongoing since that time with the biggest design improvement being just after the second world war when hydraulics were first introduced by Poclain in 1951.

Unsurprising the long reach excavator got its name due the fact that the design has a much longer arm than a traditional excavator of the same class which gives a long reach excavator the ability to reach higher and farther than a traditional one.   Long reach excavators have been on sale now for almost forty years and the longest reaching excavator known to have been put into service was developed by a British company named the Priestman Brothers that has since been bought out by R-B International.  Their long reach excavator could reach up to 83 feet and could lift 7,238 pounds of material.

Long reach excavators for sale generally have two main uses, the first is in demolition as when attempting to demolish a building, particularly in a crowded urban setting, it may not be practical to use either explosives or a wrecking ball as the collateral damage to other buildings and even people could be significant.  Instead the better solution is to use a long reach excavator as it is able to start demolishing the building from the top rather than mid way down or from the base reducing the amount of uncontrolled flying debris.

The second key use for long reach excavators is in dealing with ponds, marshes or other dredging style operations as the additional reach of the arm allows the excavator to remain on firm ground and leverage the additional reach to extend over the water and effectively dredge from the shoreline.

One of the key inventions that made the long reach excavator even more effective was the introduction of the variable counterweight.  Most excavator designs have a fixed counterweight which is usually an integral part of the cab and sets the maximum load capacity for that particular excavator.  This design, which was conceived in the 1980s works on a sliding scale allowing the operator to set the amount of counterweight required for a particular operation to prevent the boon from tipping over which is a real possibility given the additional leverage of the extended reach arm.  This feature is also extremely helpful when using the long reach excavator for dredging style operations.

In addition to the variable counterweight the key to the successful operation of any long reach excavator is the weight of the base as this, more than any other factor, sets the performance level and limits of safety for its operation.  Most modern long reach excavators for sale have sophisticated safety monitoring systems that measure the optimum length that the boom can be extended to, given the total weight that it is expected to bear and will either issue a loud warning or completely shut down the operation and retract the arm if this limit is exceeded.

It is also essential for operators of long reach excavators to wear specially designed safety equipment and have a no entry clearance zone in place during operations, as the extended height can result in any debris that escapes from the bucket having a much greater velocity as it hits the ground and a greater potential impact area.  In order to further improve protection for the operator of a long reach excavator, the cab is usually also protected by bulletproof glass, not to prevent someone from shooting the operator, but due to the fact that bulletproof glass is more than five times stronger than regular safety glass.  Most long reach excavators also have additional stabilizers that must be deployed if the boom is going to be extended more than 20 feet as in that case the counterweight may not be able to provide sufficient support.

For standard excavators there is the option to extend their arms and transform them into long reach excavators through the addition of a range of attachments that were pioneered by the Paul Wever Construction Equipment Company and can be fitted to almost all existing heavy industrial excavators.

Long reach excavators for sale that are designed specifically for demolition work have special attachments that are included as part of the standard package such as shearing and cutting units to better control the demolition process.
