Hoists and Jib Cranes in Steel Buildings: Define the Supports
Coordinate local hoists and jib cranes through equipment data, support geometry, movement, electrical services, and structural review.
Understand the project condition
A wall-mounted jib, freestanding jib, or suspended hoist can introduce concentrated equipment actions at a small part of a steel building. The apparent size of the device does not establish the adequacy of a column, rafter, purlin, or floor as its support.
For a US project, begin with the intended use and documents applicable to that site. The building manufacturer, project engineer of record, and contractors may have different scopes. Identify who provides each input and who reviews the interfaces; purchasing a metal building system does not by itself resolve foundations, building services, or occupancy requirements.

Compare decisions before fabrication release
Obtain equipment-supplier data for the intended reach, operation, support arrangement, and reactions. Identify whether loads enter the building or an independently designed support. Confirm operating sweeps and hook coverage against vehicles, workstations, and other equipment. A marked lifting rating does not authorize a field-selected attachment.
Compare alternatives on the same project basis. Record dimensions, revisions, and assumptions explicitly, and distinguish a confirmed requirement from a future possibility. When a decision changes reactions, connections, or geometry, request revised documents before authorizing affected work. A sales note or preliminary drawing should not silently become a field instruction.

Coordinate the trade interface
For building attachments, send the complete support information to the responsible structural designer. For freestanding equipment, coordinate foundations and slab assumptions with the equipment designer. Address power, access, and maintenance without adding unintended braces or ties to building steel.

Prepare a reviewable record
This matrix organizes decisions and evidence; it does not provide design capacities or tolerances. Use the project's units and elevation references, and attach complete documents when a screenshot omits applicable notes. Each review should state its scope, unresolved items, and the person responsible for closing them.
| Condition | Required record | Decision supported |
|---|---|---|
| Mounted jib | Supplier reactions and mounting detail | Review the specific building attachment |
| Freestanding jib | Equipment foundation and base requirements | Coordinate floor and below-slab conditions |
| Suspended hoist | Support locations and operating envelope | Resolve concentrated support interfaces |

Close open items and transfer the information
Keep support approvals with equipment records and identify the permitted location, actual mounting, and operating assumptions. Moving the device to another bay requires a new review of that support condition. Retain the required installation and acceptance evidence, and keep any replacement components linked to the equipment manufacturer's information. Changes in reach, attachment arrangement, or operating use should be assessed before installation rather than assumed covered by the original nominal lifting rating.
Keep the approved response available to the people performing and inspecting the work. At scope closeout, retain the final revision with its attachments, identified photographs, and resolved items. The following links develop related subjects; manufacturer details and responsible-professional direction remain necessary for the actual project.
- Identify the exact lifting device and operating use.
- Submit supplier data before selecting its support location.
- Confirm reviewed support, electrical, and maintenance interfaces.

Common questions
Can a hoist be hung from a nearby purlin?
Only with project-specific approval of the actual attachment and support; proximity is not evidence of capacity.
Does a freestanding jib rely only on slab thickness?
No. Its designer must establish the required foundation and base condition using the actual project information.

Prepare a supply inquiry
- Record the project drawing or detail and the specified product, profile, or system.
- List the complete configuration, physical units, quantities, and cuts per piece.
- Request current manufacturer documents; confirm compatibility, price, and availability before ordering.
- Obtain the responsible professional's review for loads, code requirements, or installation.
