This is what a buyer checks before they shortlist machinery and equipment suppliers.

What does a buyer check before ordering a crane or hoist?

They check safe working load and span against the building, the duty classification against how hard the crane will work, and the test and inspection certification. Duty class is what separates a crane that lasts from one that fails early, and it is routinely left out.

A works engineer is specifying lifting equipment that will be inspected regularly and must not be the reason for a stoppage.

Buyer asks

What does a buyer check before ordering a crane or hoist?

Illustrative. The question is real; it is the one this guide answers.

What buyers check in machinery and equipment

Three things, in order: what the product is, what the paperwork proves, and when each document gets asked for.

Proof load test performed before handover

Load test certificate

Asked at: before first use — legally required in most markets

That the crane is designed for the intended…

Design calculation and duty classification

Asked at: design approval

Conformity with machinery and lifting requi…

Declaration of Conformity

Asked at: before commissioning

Every claim on a supplier site has a document behind it or it does not. Buyers in cranes and hoists know which is which.

First, what the product is

The fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.

  1. 1

    Safe working load

    The headline specification, and a legal one.

  2. 2

    Span and lift height

    Must match the building structure.

  3. 3

    Duty classification

    How intensively the crane can be worked over its life.

  4. 4

    Crane type

    Overhead, gantry, jib and monorail suit different layouts.

  5. 5

    Travel speeds and control type

    Determine cycle time and operator experience.

  6. 6

    Power supply and control voltage

    Installation constraint.

  7. 7

    Wheel loads and end carriage details

    The structural engineer needs these before anything else.

Then the paperwork

Naming the documents you can issue is what separates a supplier who can be audited from one who cannot.

The shortlist moment

A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.

The buyer asks: What does a buyer check before ordering a crane or hoist?

A few suppliers get compared side by side:

A supplier with Declaration of Conformity on the page

Conformity with machinery and lifting requirements

A supplier with Wheel load and structural data on the page

Loads imposed on the building structure

A supplier with Inspection and maintenance schedule on the page

Statutory inspection intervals and what they cover

Is one of them you?

Illustrative. The documents are the ones buyers in this industry ask for.

What a useful enquiry looks like

A form that collects these fields can be answered properly the first time. A form that collects a name and a message cannot.

Enquiry form · cranes and hoists

Enough to reply usefully, short enough that a buyer finishes it.

Load to be lifted and lift height
The core specification.
Span and building details
Determines feasibility and structural impact.
Duty and cycles per hour
Sets the classification required.
Application and environment
Hot, corrosive or hazardous areas change the design.
Existing structure or new build
Decides whether the building can take the loads.
Installation window
Crane installation usually requires a shutdown.

Questions suppliers ask

Why does duty classification matter so much?

Because two cranes with the same safe working load can be designed for very different working lives. A crane classified for light intermittent use will fail early in a foundry. Publishing the classification protects you from the failures and lets serious buyers see the difference from a cheaper offer.

Should wheel loads be published before an order?

Yes, for standard configurations. The structural engineer needs them early and the project cannot progress without them. Being the supplier whose data is already available is often enough to be designed in before a competitor is even contacted.

How should service and inspection be presented?

As an ongoing obligation you support, with intervals and scope stated. Buyers of lifting equipment carry legal duties around inspection, and a manufacturer who explains those duties and offers to meet them is providing something the price comparison does not capture.

Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list.
