Excavators are primarily built for digging. The machines dig holes, trenches, and foundations for construction pillars. The hydraulic system of the excavators that power its digging capacity can also be used for a variety of other tasks, making the excavator a handy multi-tasking machine. With a little bit of tweaking, operators can extract much more from the machines. We will tell you how.
Maximize Its Lifting Capacity
Apart from its primary purpose, excavators are a handy tool when it comes to lifting and clearing material off a construction site. The bucket attached to the boom can move dirt, waste, and debris, clearing the site for construction-related activity. But before the excavator is used for lifting, follow these checks:
The machine’s capacity
Two factors play an important role here: the hydraulic capacity and the tipping capacity. The former refers to the limit when the machine runs out of power and stalls, the latter refers to the point when the machine imbalances because of an overload and may fall over. Operators need to keep in mind these two factors when using the excavator to lift loads and clear material.
Follow the lift chart
Each excavator comes with a lift chart that is made based on the machine’s design and power. Different models have different lift charts which are attached to the machine’s body, within the operator’s sight. When the machine lifts a load, operators need to keep an eye on the chart and ensure the weight does not overload the boom. One way of ensuring that the machine does not tile over is to keep the boom directly over the load before lifting it.
Factor the conditions
Since excavators are not built for lifting, the machines must be used in an ideal environment to prevent any kind of work hazard. Before lifting the load, operators should survey the ground conditions. Ensure there is a stable, firm ground for the machine to stand while lifting. Wind conditions must also be checked. A strong draft can create a side load condition, destabilising the boom. Another factor to watch out for is the kind of material that is being lifted. If the material is not easy to grip, the excavator should not be used to lift it.
Transporting the material
After the lift, the most crucial aspect for the machine is transporting the material. The operator needs to err on the side of caution and ensure the material is safely moved away from the site. The speed at which the machine moves should suit the soil conditions. If a turn has to be made, the excavator needs to have a wide turning radius. The swing radius should not be adjusted or increased after the load has been lifted.
Lift More, Lift Safe
The excavator can double as a handy lifting tool when used with the necessary safety precautions.
