GWO Slinger Signaller vs Crane and Hoist Training

Choose GWO Slinger Signaller for the load-handling and signalling role; consider Crane and Hoist Basic User for operating the small fixed lifting equipment covered by that standard. Inspection and Maintenance is a separate module. Start with the employer’s task description, then confirm the training, equipment familiarisation and authorisation required for that assignment.

Which standard is current?

Checked on 25 October 2026, GWO lists Slinger Signaller V4, dated 2 May 2023, and Crane and Hoist V2, dated 2 May 2025. Slinger Signaller is aimed at people who sling loads and signal during simple lifting operations, meaning lifts carried out to a lifting plan that covers known hazards. Crane and Hoist covers small fixed cranes and hoists, of a size such as 8 metric tons/metre, that do not require a legal or formal licence to operate at the wind farm location.

Figures come from Slinger Signaller V4 (sections 5.3 and 9.2) and Crane and Hoist V2 (sections 5.4 and 5.5). Both standards cap contact time at 8 hours per training day, so each module needs at least two days. For CHBU, an extended absence from applying the skills may lead to retraining under national legislation or company policy.

This guide helps a candidate or training coordinator choose the right module before booking; slinging, signalling and equipment operation are learned in supervised practical training. Our training partner Novikontas lists Slinger Signaller in its GWO course catalogue. A job advert that says only “GWO required” is too broad to decide which lifting course to purchase.

The distinction between user and maintenance training comes from the GWO Crane and Hoist standard. It also expects further familiarisation or equipment-specific training at the actual site. Do not read “crane” as a universal crane-operator qualification: the published scope concerns small fixed cranes and hoists used in wind-industry work.

A technician may need more than one role, but that should be an explicit decision. Ask for a written allocation of duties rather than assuming that one course title covers the entire lifting team. For example, a request to support a maintenance crew is incomplete until the employer explains whether the person will handle loads, operate equipment, inspect it, or combine selected duties.

What does a GWO lifting course not replace?

Section 7.1 of the GWO Crane and Hoist V2 standard excludes dynamic lifting, such as lifting from a crew transfer vessel moving in waves, from CHBU. Notes in sections 4 and 7.1 add that the duty holder may require further local familiarisation and always decides whether lifting operations, inspection or maintenance must be supervised. Under section 5.7, a valid CHBU record, or similar brand-specific crane and hoist user training, is a prerequisite for CHIM. Ask the provider to assess the evidence you hold before assuming you can enter the maintenance module.

GWO training also sits beneath national law. The Crane and Hoist standard states that any crane operator and slinger signaller must follow local legislation, national and regional, and its scope is limited to equipment that needs no legal or formal licence at the wind farm location. Slinger Signaller V4 section 4 adds that additional training may be required for company or country-specific reasons. Where national rules require slinger or crane-operator training, attestation or a licence, a GWO record does not replace it.

Use the equipment description, work location and actual task to test whether a proposed course is relevant. A turbine service hoist, a large mobile construction crane and equipment used for personnel movement should not be grouped into a single training requirement because their names contain similar words. If the assignment falls outside the stated learning outcomes, request a different training and competence assessment plan from the employer.

A checklist for the employer before booking

  • Write the assignment: list the person’s expected duties, equipment family, work setting and reporting line. Separate tasks they will perform from tasks they will only observe.
  • Name the module: record the full title and module code requested by the client. If several documents use different terminology, resolve the difference before purchasing training.
  • Identify the remaining requirements: ask who arranges equipment familiarisation, supervision, workplace assessment and task authorisation. Allocate those activities to a named organisation.
  • Check existing evidence: provide relevant training records and experience to the responsible reviewer. Ask what can be accepted and what gap remains; avoid booking every available course by default.
  • Set a decision date: obtain acceptance before travel or mobilisation costs become committed. Keep the confirmation with the training request so that a later coordinator can understand the choice.

For a candidate, the most useful email is a short description of the intended job plus the employer’s module request. For a coordinator buying several places, use a separate row for each person and role. Different members of one crew may have different gaps even when they travel to the same project. This makes a course quotation easier to compare and reduces avoidable rebooking.

Questions for the training provider

Ask the provider to confirm its certified scope for the exact module and delivery location, the applicable standard version, entry evidence, teaching and assessment language, and practical attendance requirements. Request a clear explanation of assessment, the training record issued, administration, and what happens if additional assessment is needed. A course being advertised is not confirmation that a particular intake has a place available.

For the commercial comparison, request the complete fee and inclusions, dates, cancellation terms, required personal equipment and any separate travel or accommodation arrangements. Keep the training booking and the employer’s acceptance as two distinct confirmations. The provider can describe its course; the employer must decide whether that course meets the assignment’s needs.

Create a useful handover after training

Retain the exact module record, completion date and the employer’s review outcome in the mobilisation file. Record any outstanding equipment familiarisation or workplace assessment with an owner and due date. If the job changes after booking, reopen the role comparison. A well-organised training file makes an unresolved requirement visible; it should never turn an unanswered question into an assumed approval.

GWO Slinger Signaller and Crane and Hoist Questions

Does Slinger Signaller also qualify me to operate a crane?
No. Slinger Signaller covers slinging and signalling during simple lifts. Operating small fixed cranes and hoists is the scope of Crane and Hoist Basic User, and the employer decides which duties each person is assigned.
How long is GWO Slinger Signaller training valid?
Slinger Signaller is an enduring qualification with no validity period, provided you actively work with slinger signalling tasks. Crane and Hoist Basic User also has no expiry, while Inspection and Maintenance is valid for 36 months.
How long does the GWO Slinger Signaller course take?
The standard sets 13 hours 40 minutes of contact time and allows no more than 8 hours of contact time per day, so the course needs at least two training days.
Is CHIM the same as a user course?
No. CHIM concerns inspection, maintenance and testing of small fixed cranes and hoists. The GWO standard makes a valid CHBU record, or similar brand-specific user training, an entry prerequisite, which the provider should check.
Does a GWO course replace national slinger or crane operator rules?
No. The Crane and Hoist standard says crane operators and slinger signallers must follow national and regional legislation, and it covers only equipment that needs no legal or formal licence at the wind farm location.
Should every wind technician buy all three modules?
No universal package follows from these course names. Match training to assigned duties and have the employer review existing competence and remaining requirements.
