Can Two People Be On a Boom Lift?

Yes – two people can be on a boom lift, but only if the platform’s Safe Working Load (SWL) and manufacturer’s instructions allow it. Boom lifts are designed with specific weight limits that include people, tools, and materials, so as long as the combined load stays within those limits and operators are properly trained, a two‑person operation is both common and safe.

Ensuring compliance with UK regulations, such as LOLER and PUWER, is also essential for safe use.

Understanding Boom Lift Capacity

Not all boom lifts are built the same, and platform occupancy depends entirely on the machine’s SWL.

According to UK boom lift safety guidance, the SWL defines the maximum weight the platform can safely support, including personnel and their equipment. Exceeding this can compromise stability and lead to accidents.

Manufacturers typically rate boom lifts for one or two occupants, though larger models may support more. Always check:

• The SWL plate displayed on the machine
• The operator manual
• Site‑specific safety requirements

It’s also important to note that some powered access equipment has different operator limits depending on whether it’s used indoors or outdoors.

For example, the Dingli AMWP11.5‑8200AC allows two occupants indoors but only one outdoors, due to stability and wind‑rating considerations.

Always check whether the manufacturer specifies separate indoor and outdoor occupancy limits before operating the machine.

Regulations That Affect How Many People Can Use a Boom Lift

Work at Height Regulations 2005

The UK’s Work at Height Regulations require that any activity at height is properly planned, supervised and carried out safely, including ensuring equipment is appropriate for the number of people using it.

Lifting Operations and Lifting Equipment Regulations (LOLER) 1998

LOLER regulations require that all lifting equipment – including boom lifts – is sufficiently strong, stable, and thoroughly examined, which directly influences safe occupancy.

Training Requirements (IPAF PAL Card)

Although there is no legal requirement to hold a valid PAL card before using powered access equipment, it is mandatory by law for an employer to ensure their employees are adequately trained in the use of MEWP equipment before they use it.

As such, many companies consider an IPAF license as a minimum requirement for jobs using MEWPS, ensuring operators understand safe load limits, platform controls, and emergency procedures.

When Two People Should Not Be on a Boom Lift

Two‑person occupancy is not suitable when:

• The combined weight exceeds the SWL
• The machine is designed for single occupancy only
• Space in the basket is restricted
• A task requires precise manoeuvring where extra weight could reduce stability

Additionally, MEWPs are not designed for people to exit the platform at height, unless under exceptional, risk‑assessed circumstances such as rescue procedures.

Best Practice for Safe Two-Person Boom Lift Use

Operating a boom lift with two people requires careful planning and adherence to safety guidance and manufacturer‑specific instructions.

Below is an expanded breakdown of best practices to ensure safe and compliant operation.

1. Verify the Safe Working Load Before Use

Before any lift, operators must calculate the combined weight of both people, their tools, and any materials and compare the total with the boom lift’s published SWL.

UK boom lift guidance emphasises that machine capacity determines how many people can safely occupy the platform and that exceeding this limit risks instability, overturning, or structural failure.

A proper load check also prevents excessive stress on the boom structure, hydraulic system, and platform basket – each of which is designed with specific load ratings.

Thorough examination of the machine under LOLER ensures lifting equipment remains strong, stable and fit for the intended number of occupants.

2. Use Trained, Competent Operators

Only trained operators should use MEWPs, and in the UK, this means holding a valid IPAF PAL card, which proves the user has completed training in safe MEWP operation, emergency procedures, and platform controls.

When two people are sharing the platform, competence is even more important. Both occupants must understand:

• How movements affect stability
• How to communicate effectively during manoeuvres
• How to avoid entrapment hazards, which the HSE highlights as a major cause of serious injuries in MEWPs

Even if only one person controls the lift, the second occupant must be briefed on hazards, emergency stop functions, and how their movements inside the platform may influence the boom lift’s balance.

Both users should have relevant MEWP training and understand site‑specific safety protocols.

3. Conduct a Risk Assessment

A proper MEWP risk assessment is required under the Work at Height Regulations and must cover factors such as:

• Ground conditions (soft ground, trenches, manholes, backfill) which can lead to overturning if not controlled
• Overhead obstructions where entrapment risk is high – especially important with two occupants sharing space
• Weather (wind speed, rain, temperature)
• Site traffic and pedestrian segregation
• Rescue planning, which the HSE says must be established before using any MEWP at height

A two-person operation increases the need for a robust plan because additional weight and movement can change how the boom responds in tight areas.

4. Maintain Communication

A two-person operation requires clear communication because:

• Boom movements must be predictable and understood by both occupants.
• Miscommunication can lead to operators becoming trapped between the basket and fixed structures, which is one of the most common MEWP hazards identified by the HSE
• In noisy or busy environments, hand signals or pre‑agreed communication protocols should be used.

The operator controlling the machine must ensure the second person is aware before raising, slewing, or driving the boom lift.

5. Follow HSE and Manufacturer Guidance

HSE guidance emphasises selecting the correct MEWP for the job, keeping the platform tidy, ensuring ground stability, and using guardrails properly.

Manufacturer instructions also provide specific occupancy limits, tool weight restrictions, and safe operating angles. Compliance with LOLER and PUWER ensures the lift remains legally compliant, safe, and structurally sound for two‑person use.

MEWPs are also not designed for exiting at height, except in strictly risk‑assessed, exceptional scenarios.

Recommended Safety Checks Before Two-Person Operation

The table below summarises critical points to review before using a boom lift with two occupants.

Safety Factor	What to Check	Why It Matters
Safe Working Load (SWL)	Confirm the combined weight of people + tools < listed capacity	Prevents instability and machine overturning
Operator Training	Verify a valid IPAF PAL card	Legal requirement for safe MEWP operation
Ground Conditions	Ensure the ground is firm, level and uncompromised	Avoids tipping, sinking or instability
Overhead Clearance	Check for beams, structures, cables	Reduces entrapment and collision risk
Rescue Plan	Ensure a ground-based rescuer knows controls	Required under HSE guidance for safe use
Weather Conditions	Monitor wind and rain	Wind loading affects MEWP stability
Platform Housekeeping	Keep tools organised, minimise trip hazards	Prevents falls and loss of balance in shared spaces
Manufacturer Guidelines	Confirm occupancy allowance and use restrictions	Ensures the machine is being used as intended

Conclusion

To answer the question simply:

Yes – two people can be on a boom lift, as long as the machine’s SWL permits it and all safety regulations are met.

Boom lifts are designed to safely lift workers to height, but staying within load limits, following UK regulations, and using properly trained operators ensures the job is carried out safely and efficiently.
