Cranes and UDT: Operator & Equipment Documents

The crane stands on the site, the operator in the cab, the first lift of a precast element. And in walks a UDT (Office of Technical Inspection) or PIP (Polish Labour Inspectorate) inspector and asks about two things: the decision clearing the equipment for operation and the operator's qualification certificate. If either is missing or expired - the crane stops, the works stop, and you lose a day and money. Cranes and hoists are equipment under technical supervision, where "it'll be fine" simply doesn't work. In this post I go through it in order: what's subject to UDT, what qualifications the operator must have and what documents to keep. If you don't want to track expiry dates in your head - at BudoReady you've got ready-made equipment registers and operator files, to enter the decision numbers and expiry dates.

Key points at a glance

• Cranes (tower, mobile, lorry-loader HDS) are subject to technical supervision - you won't move without a UDT decision.
• The basis is the Act of 21 December 2000 on technical supervision and its implementing regulations.
• The operator must have a valid UDT qualification certificate for the given type of equipment - with an expiry date.
• Renting a crane with an operator? You still check the equipment's decision and the operator's qualifications - you're responsible as the party running the works.
• The full document set: UDT decision, inspection logbook, DTR (technical and operating documentation), operator qualifications, risk assessment, equipment work plan.

What on a site is subject to UDT supervision

Let's start with what's "under the office" at all. Not every lifting device is subject to technical supervision, but most of what you lift loads with on a site - yes. The basis is the Act of 21 December 2000 on technical supervision and the regulations specifying which equipment supervision covers and in what form.

Materials-handling equipment (UTB) subject to UDT supervision includes, among others:

• Tower cranes - stationary and self-erecting on the site.
• Mobile cranes - on wheeled or tracked chassis.
• Lorry-loader cranes (HDS) - mounted on lorries.
• Hoists, winches and overhead cranes - in halls and on the site.
• Mobile platforms - scissor, articulated, boom.

Whether a specific unit is subject to supervision and in what form (full, limited, simplified) depends on its type and parameters. If in doubt - call UDT or ask the supplier. Better to ask than to get a halt. We wrote more broadly about equipment documentation in the post machine documentation - DTR, inspections, UDT.

The UDT decision - without it the equipment doesn't exist

A crane under supervision cannot operate without a valid decision permitting operation, issued by UDT after an examination. It's the first document they ask about - and the most important.

How it works step by step

1. Registration of the equipment with UDT before the first start-up.
2. Examination - an acceptance one at first start-up, then periodic and ad hoc.
3. Decision permitting operation, with an expiry date.
4. Inspection logbook - the equipment's document, in which UDT records examinations and decisions.

The types of periodic examination depend on the form of supervision. For cranes it's most often examinations on a cycle set by UDT. Exceed the examination deadline - the decision loses validity, and the equipment automatically has no right to operate. It's not "we can lift a few more times". It's a stop.

The crane operator - qualifications you must not miss

The second pillar is the person in the cab. The operator of equipment under supervision must have a UDT qualification certificate for the given type and category of equipment. Qualifications for a tower crane are not the same as for an HDS or a platform - they're categories.

The most important thing foremen miss: these qualifications have an expiry date. Qualification certificates are issued for a set period (depending on the equipment category), and before it lapses they must be renewed. An operator who did a course a few years ago may already have an expired certificate - and then formally has no right to operate the equipment.

Element	What must be there	What to watch for
UDT qualification certificate	For the specific type and category of equipment	Has an expiry date - watch the date
Operator's medical checks	Valid certificate clearing them for work	Work at height with some equipment
OSH and job-specific training	Initial, periodic, instruction for the given post	For the specific equipment
Familiarity with the DTR	Operator knows the equipment's instructions	Access to the DTR on the site

You keep copies of the certificates and medical checks on file. You enter the expiry date into the register and watch it just like the equipment's examination deadline. An operator past their deadline is, for the inspector, the same as a crane without a valid decision - equipment to be taken out of service.

Renting a crane with an operator? You're still responsible

A common scenario on small sites: you don't have your own crane, you rent an HDS or a mobile crane with an operator. And here's a mental trap - "it's not my equipment, not my problem". Well, it is yours.

As the party running the construction works you're responsible for safety on the site. If something happens, the first questions go to you. So when renting equipment with an operator:

• Check whether the equipment has a valid UDT decision - ask for a copy or the number.
• Check the operator's qualifications - a qualification certificate for the given type.
• Establish the crane's work zones - jib reach, collisions with power lines, neighbouring buildings.
• Account for it in the risk assessment and the work plan.

A few questions at the signing of the rental contract save you a halt to the works in the middle of the day.

The crane at work and its surroundings - what to remember

A crane isn't just a piece of equipment, it's a zone. When planning crane work on a site you have to sort out:

• Distance from power lines - work near overhead lines requires keeping safety zones and often arrangements with the power company.
• Stability of the footing - outriggers, mats, ground bearing capacity under a mobile crane.
• Wind - cranes have limit wind speeds at which work is halted.
• Jib collisions - with several cranes on one site.
• Signalling and the banksman - the person directing must be trained and visible to the operator.

All of this should follow from the occupational risk assessment and, for dangerous works, from the IBWR (safe work execution instruction). Works using a crane are often particularly dangerous works within the meaning of the regulations - and that means additional organisational requirements and supervision.

The documents you must have

The full set for a crane on a site:

• UDT decision permitting operation - with an expiry date.
• Inspection logbook of the equipment with examination entries.
• DTR of the equipment - in Polish, accessible on the site.
• Operators' qualification certificates - copies on file.
• Occupational risk assessment for the operator post and crane works.
• Equipment work plan / IBWR for dangerous works.
• Equipment register with examination dates and decision validity.

From 8 July 2026 the PIP reform gives inspectors stronger tools, and the fine rises to 5,000 zł. With equipment under UDT the stake is double - two inspectorates are in play at once, PIP and UDT. We've described the details of the reform in the post the PIP reform 2026 - what changes.

Frequently asked questions

Is every crane on a site subject to UDT?

The vast majority of construction cranes - tower, mobile, lorry-loader HDS - are subject to technical supervision and require a UDT decision before operation. The form of supervision depends on the type and parameters of the equipment. When in doubt, confirm it directly with UDT or the equipment supplier.

How long is an operator's qualification certificate valid?

UDT qualification certificates are issued for a set period, depending on the equipment category, and must be renewed before validity lapses. That's why the expiry date is entered on file and watched just like the equipment's own examination deadline. An operator past their deadline has no right to operate the equipment.

Am I responsible for a crane rented with an operator?

Yes - as the party running the construction works you're responsible for safety on the site. When renting you check the equipment's valid UDT decision and the operator's qualifications, and account for the crane work in the risk assessment. In the event of an accident the inspector's first questions go to you.

What are the consequences of operating a crane without a valid UDT decision?

A UDT inspector can halt operation of the equipment, and PIP can halt the works and issue a fine - from 8 July 2026 up to 5,000 zł. Operating equipment without the required technical-supervision decision is a separate breach subject to a penalty under the Act on technical supervision.
