Mobile Plant Safety

We have developed a detailed Mobile Plant Guidance for the construction plant and equipment sector. The use of Mobile Plant in construction is common and carries with it significant hazards that can affect both operators of Mobile Plant and those working around them.

Mobile Plant Safety guidance 

Within the Mobile Plant Safety guidance - you will find insightful detailed information on how to implement a machine safety management system for companies including jobs to undertake for each critical category:

1

Before procuring mobile plant

2

When managing mobile plant

3

Record keeping for each item of mobile plant

4

Record keeping for work activities

Types of Mobile Plant in Construction

Plant encompasses vehicles, machinery, equipment, tools, vessels, and even aircraft used across various industries. In construction, this includes cranes, hoists, cutting and grinding tools, compressors, and earthmoving or excavation machinery. A subset of this is Mobile Plant, which refers specifically to movable equipment commonly used on construction sites, such as:

Asphalt Pavers
Asphalt Pavers

Used to lay asphalt on roads, bridges, parking lots, and other surfaces. These machines ensure even spreading and compaction of the asphalt layer.

Mobile Cranes
Mobile Cranes

Heavy-duty vehicle with an adjustable boom used to lift, move and place heavy materials and equipment on construction sites. Features various lifting capacities and reach configurations for different project requirements.

Concrete Pump Trucks
Concrete Pump Trucks

Specialized trucks equipped with a boom-mounted pump system that precisely delivers concrete to various heights and distances. Essential for pouring concrete in hard-to-reach areas and multi-story construction projects.

Mobile Elevated Work Platforms
Mobile Elevated Work Platforms

Self-propelled machines providing safe elevated access for workers and tools. Includes scissor lifts, boom lifts, and cherry pickers, allowing work at various heights while maintaining stability and safety.

Excavators
Excavators

Tracked or wheeled machines with a boom, stick, and bucket for digging, trenching, and material handling. Versatile equipment used for earthmoving, demolition, and general construction tasks.

Rollers
Rollers

Compaction equipment used to densify soil, gravel, concrete, or asphalt surfaces. Available in various sizes and configurations including smooth drum, padfoot, and pneumatic tire designs.

Loaders
Loaders

Versatile machines equipped with a front-mounted bucket for loading, carrying, and transferring materials. Essential for moving earth, aggregate, and construction materials around job sites.

Telehandlers
Telehandlers

Multi-purpose machines combining the lifting capabilities of a forklift with the reach of a crane. Features an extending boom with various attachment options for lifting, placing, and moving materials at height.

Form a group of competent workers 

Construction work sites present a range of hazards outside of plant operation and so it is important for work area controllers to consider minimum safety standards for competency to access a construction work site.

yes
Info icon

Agree on a standard to measure 

The group should collectively decide the hazards and appropriate control measures that every worker must know, and demonstrate, to be safe in this job.

yes
Info icon

Develop and deliver materials to train workers 

Work area controllers should have the ability to access both industry and company standards when considering minimum competency standards.

yes
Info icon

Measure worker knowledge as a minimum standard 

As a minimum, it is recommended that each trained operator should be assessed to measure their understanding gained through training.

yes
Info icon

Measure worker application of skill to exceed a standard 

Once an operator has demonstrated the minimum required knowledge of the standard by succeeding in a knowledge assessment, they should then demonstrate evidence that they are applying that knowledge at work.

Mobile Plant Safety in Construction

Mobile Plant Safety in Construction

CHASNZ and industry; working together to achieve consistent site access standards and safer worksites for everyone.

When considering the question of what is reasonably practicable in the context of the HSWA the regulator and courts will apply relevant legislation, approved codes of practice

CHASNZ is seen by WorkSafe NZ as a provider of industry guidance for the construction industry.

Introduction

Introduction

The use of Mobile Plant in construction is common and carries with it significant hazards that can affect both operators of Mobile Plant and those working around them.

Under the Health and Safety at Work Act 2015, duties are placed on those who control work sites, those who own mobile plant, and those who operate it.

This guide has been created to assist these parties in planning, selecting, operating, maintaining and responsibly retiring mobile plant in a construction setting.

Types of Mobile Plant

Types of Mobile Plant

Plant includes any vehicle, machinery, equipment, tool, vessel and/or aircraft etc. Examples in construction include cranes and hoists, cutting and grinding equipment, compressors, and earthmoving and excavation machinery.

Mobile Plant is a sub sector of this group and includes a variety of machines, including common construction equipment like:

  • Asphalt pavers
  • Mobile cranes
  • Concrete pump trucks
  • Mobile elevated work platforms
  • Excavators
  • Rollers
  • Loaders
  • Telehandlers
Machine design safety considerations

Machine design safety considerations

To best understand this, your company should undertake a risk assessment to determine the best type of machine, or machines to suit the needs of the expected work activity.

When importing machinery, the buyer should verify that the manufacturing standard of the machine meets the current New Zealand, or International standard for manufacture. These can be found by visiting www.standards.govt.nz.

As part of a risk assessment process, particularly when considering a specific machine that is not newly manufactured, consideration must be given to the safety features of the machine in comparison to newly manufactured equipment.

Plant safety considerations for those controlling work areas

Plant safety considerations for those controlling work areas

The Act places duties on those who control work areas. Often in construction these are not the companies who operate mobile plant within the work site.

Those who control work areas are not always competent in assessing the requirement of mobile plant to undertake a specific task, and so there are cross over duties between the work area controller and the machine operator (or mobile plant owner).

Prior to selecting types of mobile plant for use in a work area, steps should be taken to ensure that any mobile plant in a work area is firstly safe to be operated.
