Maintaining operational safety

Mobile Elevating Work Platforms (MEWPs) are widely used across construction, industrial maintenance, marine operations, and infrastructure projects. While these machines are designed primarily for safe personnel access at height, there are circumstances where load supporting attachments may be used to assist with lifting or positioning materials.

However, fitting attachments to a MEWP introduces additional safety considerations that can affect the machine’s rated capacity, stability, and safe operating limits. To ensure safety and compliance, attachments must only be used in accordance with manufacturer approvals or guidance from a competent person and must comply with relevant Australian and New Zealand standards.

This article provides an overview of key requirements and operational considerations when using load supporting attachments on MEWPs, based on recognised industry guidance.

Understanding MEWP Load Supporting Attachments

As a trusted provider of inspection, engineering, and compliance services within the Elevated Work Platform (EWP) industry, EHL Solutions is committed to maintaining the highest standards of safety, reliability, and operational compliance. Our certified technicians and inspectors work closely with equipment owners and operators to ensure that EWPs and associated equipment meet all relevant mechanical, operational, and regulatory requirements, helping organisations operate safely while maintaining full compliance with industry standards.

A load supporting attachment is any device fitted to the extending structure or work platform of a MEWP that allows the equipment to support or handle materials in addition to personnel.

Examples may include:

• Material handling hooks
• Lifting brackets
• Pipe or equipment carriers
• Custom fabricated lifting attachments

Because these attachments alter the load distribution and centre of gravity of the platform, they must be carefully designed, approved, and used correctly to maintain safe operating conditions.

Compliance with AS/NZS Standards

Any attachment used with a MEWP must comply with the requirements outlined in:

• AS/NZS 1418.10 – Cranes, Hoists and Winches – Mobile Elevating Work Platforms
• AS 2550.10 – Safe Use of MEWPs
• WorkSafe MEWP Best Practice Guidelines

These standards specify that:

• A MEWP must not be fitted with attachments unless approved by the manufacturer or a competent person.
• The combined configuration of the MEWP and attachment must remain compliant with AS/NZS 1418.10.
• The MEWP must not be used to hoist or suspend loads unless specifically rated for that configuration.
• MEWPs must never travel with freely suspended loads.

These requirements ensure that modifications or attachments do not compromise the structural integrity or operational safety of the machine.

Required Identification and Documentation

All load supporting attachments must be clearly identified and supplied with appropriate documentation to ensure correct use.

Each attachment should include:

• A unique identifier or marking
• Rated capacity markings
• The modified rated capacity of the MEWP
• Instructions for safe operation and use
• Installation guidance
• Inspection and maintenance requirements
• A list of compatible MEWP models

Providing clear documentation ensures that operators and maintenance personnel understand the limitations and correct procedures associated with each attachment.

Key Safety Considerations Before Using Attachments

Before using a load supporting attachment, operators and supervisors should evaluate a range of operational factors to ensure safe use.

Load Capacity and Equipment Limits

The total load on the platform must account for:

• The mass of the attachment
• The weight of the load
• Personnel on the platform
• The rated capacity of extension decks

Failure to account for these combined loads can result in overloading and reduced stability.

Wind and Environmental Effects

Attachments and loads can increase the surface area exposed to wind, creating additional forces that affect stability. Wind conditions should always be assessed before lifting loads.

Load Handling and Securing

Operators must ensure that:

• Loads are securely restrained
• Safe methods are used during loading and unloading
• The load is evenly distributed

Uneven or shifting loads can create dangerous instability.

Operator Visibility and Control Access

The attachment and load must not:

• Obstruct the operator’s line of sight
• Interfere with platform controls
• Prevent safe operation of the MEWP

Clearance from Structures and Hazards

Operators must maintain safe clearance from:

• Electrical conductors
• Buildings or structures
• Other equipment

These hazards become more critical when handling suspended or extended loads.

---

Stability and Centre of Gravity Risks

One of the most significant safety concerns when using attachments is the effect on the centre of gravity of the MEWP.

Attachments that support loads above the platform guardrails increase the height of the centre of gravity, which can reduce stability and increase the risk of tipping. Additionally, wind forces acting on elevated loads can further destabilise the machine.

Careful planning and adherence to rated capacities are essential to maintaining safe operating conditions.

---

Inspection and Maintenance Requirements

Load supporting attachments are considered critical components of MEWP equipment and must undergo regular inspection to ensure continued safety and compliance.

Inspection processes should include:

• Visual inspection for structural damage
• Measurement and wear checks
• Verification of load rating markings
• Inspection of welds, fasteners, and connection points
• Confirmation that the attachment remains compatible with the MEWP

Routine inspections are essential for identifying potential faults before they compromise equipment safety.

---

Ensuring Safe and Compliant Operation

Safe use of load supporting attachments relies on a combination of:

• Proper design and manufacturer approval
• Clear identification and documentation
• Operator training and awareness
• Regular inspections and maintenance
• Compliance with industry standards

When these elements are properly managed, attachments can be used safely while maintaining the operational integrity of the MEWP.

Supporting Safe Access Equipment Operations

Ensuring safe operation of elevated work platforms is critical to protecting personnel, equipment, and worksites. Following recognised industry guidance and maintaining compliance with relevant standards helps ensure that equipment continues to operate safely and reliably.

For organisations using MEWPs with load supporting attachments, regular inspections and adherence to best practice guidelines provide assurance that equipment remains fit for purpose and compliant with regulatory requirements.
