Maintenance and cleaning for excavator attachments

How to keep excavator equipment working as long as possible? Here are some tips on their maintenance and cleaning.

Excavators and attachments get dirty every day

We must start with the clear idea that all earthmoving equipment and attachments, as well as the guest machines on which they are installed, tend to get dirty.
Machines in the construction sector (excavators, skid steers, crawler loaders, tractors and more), but also in the agricultural sector, venture into the mud and earth every day when they dig, move in the bush and among the aggregates, also contaminating themselves with pollutants. Dirt does not stop at the external structure of the construction vehicle, but also reaches the cab, where the operator works all day: dust and debris dirty the windows, reducing the driver’s visibility.

Cleaning to keep excavator attachments working much longer

While on the one hand the Covid-19 pandemic has taught us how to behave in terms of sanitizing environments and equipment in the workplace (we also talk about it in this article), on the other hand the correct cleaning and maintenance of goods materials also benefits the latter in terms of wear. The best practice is that at the end of the day the excavator operators clear the cab of their personal belongings, clean the windows of dust, throw away the rubbish produced and clean the undercarriage with a pressure washer, freeing it from dirt, rocks and debris.
Large and compact machines need to be cleaned regularly to keep them in good working order. For example, at the end of each working day, operators of excavators and crawler loaders should take the opportunity to clean dirt, rock and debris that may have accumulated in the undercarriage.
Even attachments need to be maintained as well as the machines they’re attached to: attachments are invaluable to your work projects, because they enormously expand the capabilities of construction equipment, allowing even a small fleet to perform a large range of applications.

Tips for maintaining and cleaning excavator attachments

Usually, the maintenance of a machine or attachments involves a daily inspection, developed thanks to a specific checklist like this one. Maintenance has the objective of verifying several points:

– the presence of damage due to wear and tear on the most commonly used equipment (buckets, grapples)
– the correct installation of the equipment on the host machine
– correct lubrication of moving parts, bearings, cylinders, pins and fittings
– the presence of damage to the hydraulic connections or any interruptions thereof
– the correct hydraulic pressure
– the presence of leaks from pipes and valves
– replacement of damaged parts
– the correct tightening of bolts and other fasteners

Tecnoter attachments to reduce maintenance to a minimum

We cannot avoid suggesting also to choose robust, reliable and first quality accessories/attachments to minimize the risk of accidents and wear. This choice is fundamental: once mounted on the appropriate machine, the construction accessories can be used to increase the potential of the fleet of vehicles and of the entire company.
Tecnoter attachments are now renowned for the high degree of safety they are able to guarantee even in harsh working conditions. In the Tecnoter equipment catalog you can find auxiliary stick extensions, permanent hydraulic magnets, retrofit kits and even dust reduction systems for demolition.

Hydraulic compressors in underwater demolition: how they save your equipment

tecnoter — Fri, 02 Jul 2021 15:12:25 +0000

Air compressors are popular equipment for anyone with construction experience. The particular hydraulic air compressors, less known but far safer and more useful, are designed for work in severe conditions, such as those under water.

Operations under "normal" conditions

To carry out excavation and demolition of buildings or other structures, demolition hammers are used.
The demolition hammer for excavators is essentially a hydraulic motor in which a large and heavy metal cylinder (called striking mass) is set in alternating rectilinear motion in order to repeatedly hit the tool (called tip) of the hammer itself.
During the contact between the impacting mass and the tool, the large amount of energy produced by the demolition hammer is transferred from the impacting mass to the tip (tool) and, from it, to the material to be demolished.
In order for this to happen, a compensation chamber, saturated with air, must always be present between the striking mass and the tip.
This does not involve any problems in use in “normal” conditions, or in the presence of air for the equipment.

Operations in submerged conditions

The situation is different for the construction and maintenance operations of ports and cliffs, where the excavator operator often needs to use hydraulic breakers in submerged conditions, i.e. underwater. In this condition, in fact, the compensation chamber tends to fill with water which, being incompressible, blocks the motion of the striking mass, preventing the correct transfer of energy to the tip.
This condition, in addition to preventing the hammer from functioning, causes serious damage to it.

Compressors and their contraindications

To avoid the inevitable damage to the demolition hammer, it is necessary to connect an air compressor to the hammer in order to create a sort of air bell in the compensation chamber.
Generally, classic compressors are used which, however, have several contraindications:
– they are separated from the excavator, so every movement of the excavator itself becomes difficult and leads to the waste of many hours of work
– they are bulky and noisy
– they are expensive both in terms of purchase and maintenance
Last but not least, they are also dangerous for the hammer itself because, if the motor compressor in operation were to shut down due to a fault or if a hose were to break (for example due to a sudden movement of the excavator), the hammer would strike without air with the only consequence of being damaged, even irreparably.

Hydraulic air compressors save your equipment

Hydraulic air compressors compensate for all the contraindications of classic compressors.
Installing a hydraulic air compressor on board the machine, in fact, not only allows you to solve problems of size and costs, but also allows you to immediately and automatically stop the operation of the hammer should any anomaly in the air flow occur. Thus combining greater safety and greater productivity (reducing costs).
