Controls Overview
The control pattern of the excavators is crucial to be understood as it helps in operating the excavator. These essential controls are discussed below.
- Joysticks
The joysticks in an excavator are used to control movements. The rotation of the excavator and boom is controlled by the left joystick. To lower the boom, you can push the joystick, and to raise it back, you can pull it. Also, you can move left or right to rotate the cab.
The right joystick controls the arm and bucket. It is also used for dumping the bucket by moving it, and to extend the arm, you need to push it forward. When you pull it backward, the arm comes back to its actual position.
- Pedals
The travel pedals in the excavators control the movements in the reverse and forward directions of the tracks. The swimming pedal is used for operating the swing of the upper part to ensure precise position.
- Switches
Switches in the excavators are used to control them. The excavators comprise a throttle switch, which helps in adjusting the engine speed. It also has an auxiliary switch that controls attachments like hammers. The safety lock switch that helps disable the controls when the excavator is not in use.
Safety Precautions Before Operating
When operating heavy equipment like excavators, some of the essential precautions are undertaken for the safety of the operator as well as the ground staff. Some of these safety precautions consist of the following:
Pre-Operation Inspection
The pre-operation inspection is very crucial as it helps identify any issues before using the machine. This consists of assessing the fluid level, which includes hydraulic fluid, engine oil, and fuel, so that you can assess their availability. Also, conduct a check on the undercarriage and tracks to ensure there is no wear and tear to avoid obstacles.
The functions of all the controls, like switches, pedals, and joysticks, and its right and left hand controls are also important to assess. The bucket must be checked to ensure it works properly and has no cracks.
Operator Training and Certification
The old as well as new operators must be equipped with proper training and certification so that they can operate the excavator ensuring a safe working environment. The driver’s license must be obtained, and certifications must comply with the local regulations. It helps to reduce the risk of potential hazards and accidents as a trained operator has more experience and capability.
The operators of excavators must be hired based on their training and certifications to avoid any hazardous situation. The safety of the site, as well as the staff working there, is important and is determined by how well-trained an operator is. The experience and the skills of the operator are vital and responsible for ensuring the efficiency of the overall process.
Wearing the Right Protective Gear
The operators need to wear hard hats that protect them against the debris that ends up falling and gloves to ensure a stable grip. The boots must be made of steel toes so that they protect the feet and safety glasses to protect the eyes from fluid or dust. The protective gear worn ensures protection against different types of injuries and helps minimize their impacts on the staff and operators.
When the staff is working at the site, all sorts of safety protocols are crucial, and among that, wearing the right PPE is highly stressed to ensure that in case of any accident, the injuries are minimal.
Steps for Operating an Excavator
Operating an excavator is also a technical matter; operators must be experienced enough to operate them. Most excavators are equipped with an owner’s manual, which is important to refer to before operating them.
Starting the Excavator
Starting excavators requires careful preparation to avoid accidents. A site inspection should be conducted to identify potential hazards, such as obstructions that need to be removed. The excavator should have stable soil conditions, and safety locks must be powered properly. The seatbelt should be fastened, and every control must be neutral. Once everything is sorted, the operator presses the button to start the excavator.
Operating the Controls
Operating controls are essential for efficient excavator use. The left controls of the joystick are meant to control the cab rotation and boom, whereas the right handles the bucket and arm. Precise movements help to extend and lift the bucket as required. Make sure to avoid jerky motion, as it can make the machine unstable.
Digging Techniques
The digging technique plays a vital role in the efficiency of excavation. The bucket teeth are used for soil penetration as they are angled downwards. A steady pressure is applied on the boom and digging arm to ensure efficient digging. Make sure not to overload the bucket and maintain balance.
Moving the Excavator
You can use travel pedals while moving the excavator so that the tracks are under control, ensuring slow movements. Make sure to maintain stability and avoid sudden moves when turning. The visibility must be clear when moving forward, and if you feel any jarring movement, make sure to stop the excavator.
