• Enhanced site safety

Understanding load capacity is essential when using both excavator and telehandler attachments. Incorrect loading is one of the leading causes of site accidents and equipment failure.

What Is Load Capacity?

Load capacity is the maximum weight a machine can safely lift, carry, or support under specific conditions.

It depends on:

• Machine size and model

• Boom extension (telehandler)

• Lift height and reach

• Attachment weight

• Ground conditions

• Load centre distance

Telehandler Load Capacity Explained

Telehandlers have variable load capacities. The further the boom extends, the lower the lifting capacity.

Key Factors:

• Boom angle

• Boom extension length

• Attachment weight (jib, bucket, platform)

• Load centre (distance from carriage)

Always consult the manufacturer’s load chart inside the cab before lifting.

Important:
Adding a heavy attachment reduces available lifting capacity.

Example:

• Machine rated at 3,000kg

• Attachment weight = 500kg

• Maximum safe load = 2,500kg (subject to reach/height)

Excavator Lifting Capacity Explained

Excavators are primarily designed for digging — not lifting — but can be used for lifting operations when properly configured.

Key factors affecting lifting capacity:

• Radius from machine centre

• Over-front vs over-side lift

• Counterweight size

• Attachment weight

• Ground stability

Always:

• Use certified lifting points

• Follow lifting operation regulations

• Check lifting charts

• Ensure competent operator training

Failure to understand load capacities can result in:

• Machine overturning

• Structural damage

• Dropped loads

• Serious injury or fatality

• Legal prosecution

Proper training and supervision are essential for safe operation.

When selecting an attachment, consider:

1. The job requirements

2. Machine compatibility

3. Hydraulic flow requirements

4. Attachment weight

5. Required lifting capacity

6. Compliance with safety regulations

Working with a trusted supplier ensures:

• Correct specification

• Proper certification

• Full compatibility

• Ongoing support

Correct rigging and lifting techniques are essential for safe excavator and telehandler operations. Poor rigging can lead to load shift, instability, dropped loads, or serious injury.

Key Principles

• Use certified lifting points only – Never lift from bucket teeth or non-rated components.

• Select the correct lifting accessories – Chains, slings, and shackles must be rated for the load.

• Check the SWL (Safe Working Load) – Include attachment weight in your calculations.

• Keep loads balanced – Ensure even sling angles and correct load centre positioning.

• Use a trained signaller or banksman – Clear communication reduces risk.

• Avoid sudden movements – Lift smoothly and avoid rapid slewing.

Before Every Lift

• Inspect lifting gear for damage

• Confirm load weight

• Check the machine’s load chart

• Ensure firm, level ground

• Establish an exclusion zone

Safe rigging protects operators, ground workers, and equipment while ensuring compliance with site safety standards.

Summary

Effective rigging and lifting require certified lifting points, correctly rated slings or chains, accurate load calculations, and controlled machine movement. Always inspect equipment, confirm load weight, follow the machine load chart, and use competent personnel to maintain safety and stability during lifting operations.

Clear communication is critical during any lifting operation involving excavators or telehandlers. Poor communication is a leading cause of dropped loads, collisions, and serious site injuries.

Key Communication Principles

• Appoint one designated signaller (banksman) – Only one person should give signals to the operator.

• Use standard hand signals – Ensure all personnel understand recognised site signals.

• Maintain constant visual contact – If visibility is lost, stop the lift immediately.

• Use two-way radios when necessary – Particularly on large or restricted sites.

• Confirm instructions clearly – Repeat back key commands if needed.

Before the Lift

• Hold a brief lift discussion (toolbox talk if required)

• Agree on signals and communication methods

• Identify blind spots and exclusion zones

• Confirm emergency stop signal

If Communication Is Lost

Stop the operation immediately and lower the load to a safe position before continuing.

Summary

Maintaining clear communication during lifting operations prevents accidents and instability. Always use a single trained signaller, standard hand signals, and clear visual or radio contact. If communication is lost, stop the lift immediately to maintain safety and control.

Do Not Exceed the Excavator’s Reach Limits

Exceeding an excavator’s rated reach is one of the most common causes of instability and overturning incidents on site. Excavators are designed primarily for digging, not lifting — and their lifting capacity reduces significantly as the load moves further away from the machine’s centre of rotation.

Understanding reach limits is critical for safe lifting operations, regulatory compliance, and preventing costly damage or injury.

Why Reach Limits Matter

An excavator’s stability is based on three core factors:

1. Load weight

2. Lift radius (reach)

3. Machine configuration

As the boom extends outward:

• The lifting capacity decreases

• The tipping risk increases

• Ground pressure changes

• Hydraulic strain increases

The further the load is from the undercarriage, the greater the overturning force applied to the machine.

Understanding Lift Radius vs Boom Length

Many operators confuse boom length with safe working radius.

• Boom length = Physical extension of the arm.

• Lift radius = Horizontal distance from the centre of rotation to the load.

It is the lift radius, not just the boom extension, that determines safe lifting capacity.

Even small increases in radius can dramatically reduce safe lifting capacity.

Over-Front vs Over-Side Lifting

Excavators are generally more stable when lifting over the front (in line with the tracks) compared to over the side.

Over-Front Lifting

• Greater stability

• Higher lifting capacity

• Lower overturn risk

Over-Side Lifting

• Reduced stability

• Lower safe working load

• Higher risk of tipping

Always refer to the machine’s load chart for specific rated capacities in each position.

What Happens When Reach Limits Are Exceeded?

Exceeding recommended reach limits can result in:

• Forward tipping

• Side rollover

• Sudden load drop

• Structural boom damage

• Track lift-off

• Ground failure

Even if the machine does not fully overturn, repeated overload stress can weaken pins, bushings, and hydraulic components — leading to long-term damage.

The Role of the Load Chart

Every lifting-configured excavator has a manufacturer’s load chart inside the cab.

The load chart accounts for:

• Boom configuration

• Dipper length

• Counterweight

• Undercarriage width

• Lift radius

• Lift height

Never estimate capacity based on “feel” or previous experience. Always verify using the load chart.

Ground Conditions and Reach

Extended reach increases ground pressure at the front or side of the tracks.

On soft, uneven, or uncompacted ground:

• Stability reduces significantly

• The risk of sudden collapse increases

• Track sinking can shift the load centre

Before lifting:

• Ensure firm, level ground

• Use suitable mats if required

• Avoid lifting across slopes

Additional Factors That Reduce Safe Reach

Even if within the stated radius, capacity may be reduced by:

• Heavy attachments (grabs, breakers, buckets)

• Quick hitch weight

• Lifting chains or slings

• Wind load on large objects

• Dynamic movement or swinging

All attachment weight must be deducted from the rated lifting capacity.

Safe Working Practices

To avoid instability when lifting with an excavator:

• Never exceed the rated lift radius

• Keep loads as close to the machine as possible

• Lift over the front where practical

• Avoid sudden slewing movements

• Do not travel with suspended loads unless approved

• Use lifting points, not bucket teeth

• Ensure operator competence and lift planning

For complex lifts, follow proper lifting procedures under applicable regulations and ensure supervision by a competent person.

Signs You Are Approaching Instability

Operators should stop immediately if they notice:

• Tracks beginning to lift

• Machine rocking

• Excessive hydraulic strain

• Loss of smooth control

• Load swinging uncontrollably

If instability occurs:
Lower the load immediately and reassess.

Excavator lifting capacity decreases as reach (lift radius) increases. Extending beyond the manufacturer’s recommended limits shifts the load centre away from the machine, increasing tipping risk. Over-front lifting offers greater stability than over-side lifting. Always consult the load chart, account for attachment weight, assess ground conditions, and keep loads as close to the machine as possible to prevent instability and overturning incidents.

Ensure that operators are properly trained and certified for lifting operations. Holding the NPORS Excavator As A Crane bolt on is essential for lifting operations Operating an excavator as a crane requires specific skills and knowledge.

Consider weather conditions, especially wind speeds, as they can affect the stability of the excavator during lifting operations.

Always prioritise safety when using equipment for tasks it wasn’t originally designed for. If the lifting requirements are frequent or extensive, it may be more appropriate to use a dedicated crane with the necessary capacity and features. Remember, safety is paramount in any construction or lifting operation.
