There is no single crew size that fits every crushing operation. A site with an established foreman and equipment operators may need one specialized plant operator. A different project may need several connected roles to cover a defined shift or temporary production period.
Use this checklist to identify the people the client already provides, the responsibilities still open and the site conditions that shape the requirement. It is an employer planning aid, not an engineering staffing standard or a guarantee that ROC can supply a particular crew.

01 / Draw the Boundary Around the Operation
Start with the equipment and process actually included in the project. Is the scope a mobile jaw-and-screen spread, a fixed multi-stage plant, dedicated screening, load-out support or some combination? Which equipment is supplied and operated under the client's existing organization?
List the project location and operating period. A short road-building job, a long-running quarry and a remote mine-support assignment may share equipment names but have different logistics, supervision and access conditions.
02 / List the Functions That Must Be Covered
A practical functions map can include:
| Function | Responsibility to define | Filled by client? |
|---|---|---|
| Plant / crusher control | Equipment and process duties within authorized role | Yes / No / To confirm |
| Screening / conveying | Dedicated position or combined defined responsibility | Yes / No / To confirm |
| Feed equipment | Loader, excavator or other assigned feed duties | Yes / No / To confirm |
| Product / stockpile handling | Movement, loading or stockpile support | Yes / No / To confirm |
| Ground / plant support | Assigned observation, communication and site support | Yes / No / To confirm |
| Shift supervision | Who directs the team and communicates with client management | Yes / No / To confirm |
| Trades / maintenance | Specialist duties performed by qualified authorized parties | Yes / No / Separate contract |
This is a discussion map. It is not a declaration that each function needs a separate person, or that one person may safely perform several duties at once. Staffing, competence and segregation of responsibilities are site-specific decisions.
03 / Map Each Shift Separately
For each shift, record which equipment will operate, who is already present and which positions remain open. Note handover and supervisory coverage. Do not assume that an added night or weekend shift can use an identical staffing plan if other support functions are different.
Where the project involves rotational work, note shift length, on/off pattern, travel days and camp arrangements. If the work is in a remote location, those factors affect who could realistically consider the assignment. See Remote & Project Deployment.
04 / Example: One Missing Critical Position
Illustrative scenario—not a client project or a quoted ROC service package.
A quarry operates a fixed circuit with an established loader team, supervisor and ground support. A crusher-operator position will be unfilled for a defined period. The first request is for the operating responsibilities of that position, the specific control arrangements and the period to be covered—not an entire replacement crew.
The key questions are: what duties the previous operator performed, whether any work must be reassigned, who will supervise and how site-specific requirements will be met. See Crusher Operator Coverage.
05 / Example: Temporary Additional Shift
Illustrative scenario—not a confirmed ROC crew configuration.
A mobile aggregate spread is scheduled for more operating hours during a civil project. The client already has equipment and some staff, but needs to define additional plant operation, feed support and shift oversight requirements. The first step is a shift-by-shift functions map, not an assumed fixed headcount.
The exact staffing arrangement depends on the equipment, worksite, roles, authorized duties and applicable requirements. See Added Shifts & Project Surges.
06 / Site Readiness and Responsibility Checklist
Before a possible assignment proceeds, the project may need to resolve:
- Who supplies and controls the plant and supporting equipment.
- Who directs daily production and safety procedures.
- Equipment-specific training and orientation obligations.
- Required licences, tickets, inductions and client approvals.
- Responsibility for accommodation, travel, site access and personal protective equipment under the actual agreement.
- Commercial scope, working hours and any agreed change process.
- Which tasks are reserved to specialist trades or other qualified parties.
Do not assume all of these have been approved simply because a potential operator has relevant experience.

08 / Crew Planning FAQs
Does a complete crew come with a fixed number of people?
No. The published ROC workforce concept is configuration-based. Actual staffing requirements depend on the project and must satisfy applicable site, equipment, labour and safety requirements.
Can the client supply some of the people?
A project brief can identify positions already staffed by the client and positions for which outside support is being discussed. Any resulting arrangement requires agreement on roles and responsibilities.
Can ROC guarantee full crew availability?
No. Availability, qualifications, commercial conditions and project suitability require separate confirmation.
09 / Bring the Right Questions to the First Conversation
A good crew plan makes responsibility visible. Start by identifying what the plant needs, what the client already has and which roles remain unresolved.
