There are two 'factors' that playa crucial role in appropriate excavator operation.One of them is a skilled operator and another is a correct use of operator controls. Today, we want to look closer at the latter and the operator control patterns and safety tips that will help you enjoy smooth excavator operation.

Excavator Control Patterns - ISO Controls vs SAE Controls

Explaining how the excavator controls work must start from the introduction of two types (patterns) of control systems you can find in excavators, ISO controls or SAE controls.These patterns were established by two governing bodies, the International Organization for Standardization (ISO), and the Society of Automotive Engineers (SAE). The patterns are used in machines that have digging applications, such as excavators or backhoes.

Where Are the ISO Controls Used?

ISO control pattern isthe most used control pattern.It was established by the International Organization for Standardization. This non-government body setsthe manufacturing standards in various fields, including management, tech, and construction.Therefore, control patterns, machine power, attachment capacity, and many other areas are outlined in a special document, ISO 10968: Earth-moving machinery Operator's controls. ISO patterns are also called CAT controls, as they are frequently used in CAT machines.

Who Uses the SAE Controls?

SAE controls are more commonly used in machines in the USAthan in the rest of the world. The reason for that is that the Society of Automotive Engineers is based in the United States. Construction standards set by the SAE are like the ISO standards. Both ISO and SAE are used by the manufacturers who make sure that the machines operate according to these codes of conduct. SAE controls are often used in John Deere machines which is why they are often calledJohn Deere Controls.You can also come across the name'backhoe controls'.

ISO Control Pattern Explained

ISO pattern joystick controls work in the following way:

1. The use of a left-hand joystick (lever)helps to controlthe turns the machine makes.At the same time, it allows to maintaina fixed posturein the traction system and arm movements. Thanks to the left joystick you cancontrol the proximityof the bucket to the equipment:
   -Moving the left joystickforwardmakes the dipper (stick) move forward(away from the excavator);
   -Moving the left joystickbackwardmakes the dipper (stick) move backward(towards the excavator);
   -Moving the left-hand joystickto the leftswings the excavator's cabin and coreto the left;
   -Moving the left-hand joystickto the rightswings the excavator's cabin and coreto the right;
2. The use of a right-hand joystick (lever)lets the operatorcontrol the bucket and boom movements:
   -Moving the right joystickforwardmakes the main boom movedownwards;
   -Moving the right joystickbackwardmoves the main boomupwards;
   -Moving the right joystickto the leftmakesthe bucket close;
   -Moving the right-hand joystickto the rightmakesthe bucket curl outwardsand drop its load.

How Does the SAEControl Pattern Work?

Let us now analyze how to operate the machine using the SAE pattern:

1. The left-hand joystick (lever)is used to operatethe boomand swing in the following way:
   -Moving the left joysticktowardsyou raises the main boom(upward move);
   -Moving the left joystickforwardlowersthe main boom;
   -Moving the left-hand joystickleftswings the turretleft;
   - Moving the left-hand joystickrightswings the turretright;
2. The right-hand joystickis used to operatethe dipper and the excavator bucket:
   -Moving the right-hand joysticktowardyou brings the dippertowardthe machine;
   -Moving the right-hand joystickforwardextends the dipperawayfrom the machine;
   -Moving the right-hand joystickto the leftcurls bucket in(inward move);
   -Moving the right-hand joystickto the rightcurls the bucket out anddumps material.

Can I Change the Control Pattern in My Machine?

Some operators may already be used to operating a certain control pattern. Therefore, it would be easier to stick to it no matter the type of equipment you operate. The good news is thatsome newer machine models may offer a switch between the control patterns.It may come as a lever under the floorboard or behind a panel in the cab. If you are unsure,get in touch with the machine's manufacturer.

Basic Safety Tips on Operating an Excavator

Before operating any machine, no matter if it uses the ISO controls or SAE controls, the operator must ensure a safe operation. Therefore, we present you with a few best practices that will help yousafely complete any job.

Step #1: Safety Check

Before starting the operation, ensure youconduct a safety check.It will indicate whether the machine is safe to use not only for the operator but also for all the others in its surroundings. This pre-operation safety check alsocontributes to the longer life of your equipmentand detects minor problems before they turn into serious issues.

The pre-operation safety check consists of:

1. Inspecting whether there are anyhazards in the surroundings;
2. Walking around the machine and checking whether allmachine parts are undamaged,especially:
   - Under the machine (leaks);
   - The tracks (tension or loose components);
   - The boom and the bucket.
3. Checkingfilters and fluid levels,including fuel;
4. Performing lights and controls checks.

Step #2: Enter the machine's cabin

Firstly, before entering your machine ensure yousecure and lock the door.That will enable you to safelyuse the handleto help you climb. You should have three contact points during your climb. When you sit down in the cab, perform three below actions:

1. Put your seat belt on
2. Close the door
3. Ensure you know all the controls before starting the operation.

After you have sat down comfortably and safely in the cab you can start looking outside of your cab.

Step #3: Examine the surroundings

It is imperative toalways be aware of what is around your machineon the site. You mustensure the safetyof other equipment and people. Look not only around but also up and examine what lies beneath the surface. There might beoverhead or underground linesyou might damage by moving the attachment up or by digging. If you move forward, make sure you keep your bucket a maximum of one or two feet off the ground to ensure the best visibility. Toavoid damaging overhead structureslower the dipper and curl the bucket into the maximum. At such times, be aware that your front visibility will be reduced.

Step #4: Maintenance

Proper maintenance is a crucial part of keeping your equipment safe.The instructions on how to properly maintain your machine are a part of the operator manual. It will list the parts of your machine, its controls, and other features and information.

Safety Comes with High Quality Equipment

Using older construction equipment requires a lot of caution. Older parts tend to break or wear. The key to avoiding damage and malfunctions isusing high-quality components and attachments.Regardless of whether you use the ISO control pattern or the SAE controls, good operation is only guaranteed byusing proper equipment from a trusted supplier.If you are looking for a foolproof excavator attachment for your farming, landscaping, or construction project, our equipment is the best choice.
