Hammers

designed and manufactured in Italy for every phase of demolition.
OSA Demolition Equipment was founded in 1994 in Molfetta, in southern Italy, and from there designs, manufactures and exports demolition equipment with its own facilities and R&D department.
Since July 2025 it is part of the Sandvik group, as a demolition tools unit alongside Rammer. Two brands, one backing.
At PSI we work with a selection of its range: the machines that best respond to our clients' jobs, with advice, custom coupler and technical service.

Questions about OSA equipment.
Can't find your answer? Call us and speak to a technician, not an answering machine.
What OSA equipment does PSI sell?
HB and MB hydraulic hammers, GR sorting and demolition grapples, SH shears, RS demolition grapples, RV rotating and FPV fixed pulverizers, and MC multiprocessors. On this page you'll find all available models.
What is the relationship between OSA and Rammer?
Since July 2025 OSA has been part of the Sandvik group, the same group to which Rammer belongs. At PSI we work with both brands.
Do the machines come with the coupler for my excavator?
We prepare the attachment bracket (welded bolts or lugs), the plate and the right hoses for your machine. Ask us about other types of attachment.
How do I choose the equipment size?
The key figure is the weight of your carrier; for shears, also whether they are mounted on the linkage or boom. Each data sheet indicates the recommended range, and we confirm hydraulic compatibility.
Can I buy the multiprocessor frame without jaws?
No. The MC multiprocessor frame is always supplied with at least one jaw kit.
