Up to 250 jobs could go at US multinational Caterpillar's plants in Northern Ireland, a spokesman has said.
The proposals include the possible closure of the Monkstown facility near Belfast and the consolidation of operations in Larne in Co Antrim and Springvale in Belfast.
The manufacturing firm is considering discontinuing production of 25-tonne and larger material handlers in Northern Ireland, including the planned launch of large material handler models for Europe.
If finalised, production for electric power generator sets in Monkstown would be consolidated into Larne and manufacture of truck axles will move into Springvale.
A company statement said: "These actions could result in the reduction of between 200 to 250 production, support and management positions across the Northern Ireland facilities."
Caterpillar employs around 1,800 people in Northern Ireland.
It has four facilities - Larne, Monkstown, Springvale and Belfast offices beside the Springvale plant.
It makes generator sets and carries out other forms of manufacturing, including the assembly of axles for articulated trucks and the manufacture of wheeled material handlers.
It also has a shared services centre in Belfast with people employed in areas including finance and human resources.
The generator sets are used for prime and standby electric power for customers such as hospitals, utilities and data centres.
