What Are Underslung Loads in Construction?
In the context of construction plant machinery, an underslung load refers to any item lifted and transported while suspended from a dedicated lifting point, typically a hook or shackle attached beneath the machine’s boom. This method is fundamentally different from scooping materials inside a bucket or carrying a pallet on forks. It involves using chains, slings, or other certified lifting accessories to secure the load, allowing for precise placement and the movement of awkwardly shaped items.
While the term might bring to mind aviation and the use of a specialised helicopter cargo hook, the principles of managing a free-swinging load are just as critical on a building site. Our focus here is strictly on ground-based plant, where accredited operators use machines like excavators and telehandlers for these specialised lifting operations, demanding a high degree of skill and safety awareness.
Key Terminology: Underslung vs. Suspended Loads
It’s important to understand the distinction between these terms. A ‘suspended load’ is a broad category for any load hanging from lifting equipment. An ‘underslung load’ is a specific type of suspended load, characterised by being attached underneath an excavator boom or similar attachment. This distinction is vital, as handling underslung loads introduces unique dynamic forces and requires specific, accredited suspended load training like an NPORS certification to ensure operational safety and compliance.
Common Applications on a Construction Site
The ability to safely manage underslung lifting tasks transforms standard plant machinery into highly versatile tools. Certified operators are frequently required to:
-
Lift and lower materials like pipes, manhole rings, and concrete blocks into trenches or excavations.
-
Precisely place structural components, such as steel beams or timber trusses, over obstacles or onto foundations.
-
Load and unload heavy or cumbersome materials from transport vehicles where a crane is not available or practical.
-
Manoeuvre equipment like generators or pumps into hard-to-reach areas of the site.
Mastering this skill enhances the utility of excavators and telehandlers, making them indispensable assets for a wide range of site activities.
The Lifting Team: Key Personnel & Responsibilities
A common misconception is that the safe movement of underslung loads rests solely on the shoulders of the machine operator. In reality, a successful and compliant lift is a meticulously coordinated team effort. Under UK regulations like LOLER 1998, every individual involved has a legal responsibility to ensure safety. Flawless communication and a clear understanding of each person’s duties are not just best practice-they are essential for preventing accidents and ensuring the operation runs smoothly.
Three core roles form the backbone of any professional lifting team: the Plant Operator, the Slinger Signaller, and the Lift Supervisor. Each role is distinct, requiring specialised training and a commitment to safety-first principles.
The Role of the Plant Operator
The Plant Operator is in direct control of the lifting equipment, but their responsibilities begin long before the engine starts. They must be competent, certified, and fully focused on the task at hand. Key duties include:
-
Pre-Use Checks: Meticulously inspecting the lifting appliance (e.g., crane, telehandler) and any lifting gear provided to ensure it is safe for use.
-
Precise Operation: Operating the machinery smoothly and without sudden movements, responding only to the signals from the designated Slinger Signaller.
-
Understanding Load Limits: Having a thorough knowledge of the machine’s lifting capacity chart to ensure the load never exceeds its safe working limit (SWL).
-
Correct Certification: Holding a valid and appropriate NPORS certification for the specific category of plant being used for the lift.
The Critical Role of the Slinger Signaller
The Slinger Signaller is the crucial link between the operator in the cab and the load on the ground. They are the operator’s eyes and ears, a role that is especially vital when handling complex or awkwardly shaped underslung loads where the operator’s view is obstructed. Their responsibilities demand high levels of skill and attention to detail.
-
Load Management: Correctly attaching and detaching the load, ensuring it is secure, balanced, and free of potential snags before lifting commences.
-
Accessory Selection: Choosing the correct, certified lifting accessories (slings, chains, shackles) for the load’s weight, shape, and centre of gravity.
-
Clear Communication: Directing the Plant Operator using a clear, pre-agreed system of standardised hand signals as specified by BS 7121.
The Authority of the Lift Supervisor
The Lift Supervisor is the person with overall control of the lifting operation. They are responsible for planning, briefing the team, and ensuring the work is carried out in accordance with a comprehensive lift plan. This plan is a legal requirement under LOLER and must account for all variables, drawing on established best practices, such as the comprehensive guidance found within British Standard BS 7121 (Code of practice for the safe use of cranes). The Lift Supervisor has the ultimate authority on-site and must stop the operation immediately if they believe it has become unsafe for any reason. Their role is to lead from a position of expertise, ensuring every safety protocol is followed without compromise. Join our lift supervisor training in Gloucestershire

Machines & Equipment for Underslung Load Operations
Selecting the correct plant machinery is the first critical step in any operation involving underslung loads. While many sites have excavators and telehandlers readily available, it is a dangerous misconception that any machine is suitable for lifting. Only specific models, correctly configured and certified for lifting duties, should ever be used. Using manufacturer-approved lifting points is not just best practice; it is a fundamental safety requirement.
Using a 360 Excavator as a Crane
A 360 Excavator is a versatile machine, but using it as a crane requires specific safety features and operator competency. To be used for lifting, the excavator must be fitted with check valves on its hydraulic rams. These essential devices prevent the boom and arm from dropping suddenly in the event of a hydraulic hose failure. The lift must be conducted using either a manufacturer-fitted, certified lifting point or a correctly rated quick hitch attachment designed for the task. This specialised skill is covered in accredited courses like the NPORS N100 Excavator as a Crane Training category.
Telehandler with Underslung Load Attachments
Telehandlers are frequently used for lifting operations, typically with a dedicated lifting hook attachment fitted to the jib. Unlike a static crane, a telehandler’s capacity is highly dynamic. The Safe Working Load (SWL) changes dramatically based on the boom’s extension and angle. It is absolutely vital that the operator understands and strictly adheres to the machine’s specific load chart before every lift. Attempting a lift without consulting this chart can easily lead to instability and catastrophic failure. The NPORS Telehandler (Suspended Loads) Training ensures operators have the certified skills for these tasks.
Essential Lifting Accessories
The machine is only one part of the system. The accessories that connect the machine to the load-such as slings, shackles, chains, and hooks-are equally critical to safety and compliance. All lifting accessories must be fit for purpose, certified, and subject to regular, documented inspections. As defined by the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), this equipment requires a ‘thorough examination’ by a competent person. Pay close attention to visual aids like the colour codes on synthetic slings, which indicate their SWL, ensuring the correct sling is chosen for the weight of the load.
Safety First: Complying with LOLER and Creating a Lift Plan
In the United Kingdom, all lifting operations are governed by a critical piece of legislation: the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER). This is not just guidance; it is a legal requirement designed to ensure every lift is conducted safely. LOLER’s scope is comprehensive, covering the lifting machine itself, all lifting accessories like slings and shackles, and, most importantly, the people involved in the operation.
The core principles are clear and non-negotiable: every lift must be properly planned by a competent person, appropriately supervised, and carried out in a safe manner. At Vally Plant Training, our NPORS-accredited courses are built around these principles, ensuring your team has the expert knowledge to achieve full compliance and maintain the highest safety standards.
What LOLER Means for Underslung Loads
For operations involving underslung loads, LOLER compliance is paramount. It mandates a systematic approach to safety, moving beyond simple operational skill to a fully documented and verifiable process. Key requirements include:
-
Thorough Examination: All lifting equipment and accessories must undergo regular, documented examinations by a competent person to ensure they are fit for purpose.
-
Competent Personnel: Every individual involved, from the crane operator to the slinger signaller, must be trained, certified, and deemed competent to perform their role safely.
-
Proper Supervision: A designated lift supervisor must oversee the operation to ensure the lift plan is followed precisely.
-
Record Keeping: Detailed records of all examinations, inspections, and lifting operations must be maintained and made available for inspection.
The Four Key Elements of a Lift Plan
A lift plan is the essential blueprint for a safe operation. It is a formal document that details exactly how the lift will be carried out, mitigating risks before they arise. A robust lift plan contains four key stages:
-
Assessment: Evaluating the load (weight, dimensions, centre of gravity), the lift path (from start to finish), and identifying all potential site hazards, such as overhead power lines or unstable ground.
-
Planning: Selecting the correct machine for the load, choosing the appropriate lifting accessories, and assigning certified personnel to each role.
-
Briefing: Communicating the plan to the entire lifting team through a toolbox talk. This ensures everyone understands their specific responsibilities, the communication methods, and the emergency procedures.
-
Supervision: Actively monitoring the lift from start to finish to ensure strict adherence to the briefed plan.
Pre-Lift Checks: A Practical Checklist
Immediately before the lift begins, the operator and slinger signaller should conduct a final series of practical checks. This is the last opportunity to spot a potential issue on the ground.
-
✔ Machine: Visually inspect the lifting machine for any hydraulic leaks, structural damage, or warning lights.
-
✔ Accessories: Check all slings, shackles, and chains for signs of wear, stretching, corrosion, or other defects. Never use damaged equipment.
-
✔ Work Area: Confirm the ground is firm and level. Ensure the planned exclusion zone is clear of all personnel and obstacles.
-
✔ Communication: Perform a radio check or confirm that hand signals are clearly understood between the operator and signaller.

Frequently Asked Questions About Underslung Loads
Can any 360 excavator be used for lifting underslung loads?
No, not every 360 excavator is suitable for lifting operations. A machine must be specifically designed for lifting and comply with UK LOLER 1998 regulations. This includes having essential safety features like check valves on the hydraulic rams to prevent the boom from dropping, and a rated capacity indicator. The machine must also have a manufacturer-approved, certified lifting point. Using a standard digging bucket for lifting is unsafe, non-compliant, and strictly prohibited on any professional worksite.
What is the difference between an underslung load and a standard suspended load?
The primary difference relates to the type of machinery used. A standard suspended load is typically lifted by a purpose-built crane. In contrast, an underslung load is suspended from an attachment on a piece of plant, like an excavator or telehandler, which is not primarily designed for lifting. This distinction is vital for safety and planning, as it requires specific operator training, a different risk assessment, and strict adherence to the plant manufacturer’s guidelines for that specific lifting task.
How often do I need to refresh my NPORS underslung load certification?
For a traditional NPORS Operator Card, it is best practice to undertake refresher training and assessment every three to five years to maintain safety standards and ensure your knowledge is current. If you hold an NPORS/CSCS Trained Operator ‘red’ card, you are required to complete the relevant NVQ within two years. Upon successful completion, you can upgrade to a Competent Operator ‘blue’ card, which is then renewable every five years through a renewal test and an up-to-date HS&E test.
Is a Slinger Signaller legally required for every underslung load lift?
Under LOLER 1998, every lifting operation must be safely planned and supervised. A qualified Slinger Signaller becomes legally essential if the machine operator’s view of the load or the landing zone is obscured at any point. For the vast majority of complex lifts involving underslung loads, a Slinger Signaller is a critical component of a safe system of work, ensuring clear communication and precise guidance between the operator and the lifting team on the ground.
What is a lifting capacity chart and why is it so important?
A lifting capacity chart, or load chart, is a manufacturer-provided diagram located inside the machine’s cab. It details the machine’s Safe Working Load (SWL) at various heights, angles, and radii. This chart is not a suggestion-it is a mandatory limit. Exceeding these capacities can cause the machine to tip over or suffer a catastrophic structural failure. Every operator must be expertly trained to read and understand this chart before attempting any lifting operation.
Does my standard NPORS Telehandler ticket cover underslung loads?
No, a standard NPORS N010 Telehandler certification does not cover the lifting of underslung loads. This task requires a specific, separate endorsement, which is the NPORS N138 Telescopic Handler – Underslung Loads qualification. This dedicated training and assessment covers the unique risks, machine stability calculations, and safe operating procedures required for this specialised type of lift. Always check that your NPORS card lists the precise category for the work you are undertaking.
