Pile cage machines
built for continuous production.
EMG designs and manufactures the SLP series: automatic reinforcement cage welding machines with PLC-controlled welding, for cages up to Ø3000 mm and 24 m.
Consistency is what a foundation pile asks of a cage. The SLP is built around it.
Three engineering advantages, present on every model of the series.
Consistent welding quality
Welding parameters are controlled automatically by the PLC. Weld time stays constant whatever the rotation speed, so every crossing is welded the same way, cage after cage.
Industrial reliability
Heavy-duty, modular construction: a massive frame, reinforced lifting, direct-drive heads, dual rack-and-pinion carriages and brushless motors, designed for long shifts and heavy cages.
Repeatable output
PLC-guided setup, stored recipes and a reference-scale positioning disc make format changes fast and reduce reliance on specialised operators.
One welding principle. Six models. Cages from Ø100 to Ø3000 mm.
Each largest cage is drawn in section, to scale: the spiral ring and the longitudinal bars at the maximum diameters of each model. Every SLP shares the same welding principle.

Sections to scale by cage, spiral and bar diameter. The number of bars is illustrative; it is set by the cage design.

MIG torches, dual-torch welding available as an potion
The PLC runs every weld.
Cage recipes are standard. On the SLP, the welding itself is controlled by the PLC: weld triggering, weld time and welding parameters, saved as presets and recalled for each cage.
Constant weld time
Independent of rotation speed. Pitch, geometry and weld quality stay consistent.
Dual-torch MIG welding
Two torches shorten the cycle on every cage.
Guided format changes
A reference-scale positioning disc speeds bush placement; the PLC guides the operator step by step.
Connected machine
Barcode integration, diagnostics, data export and online connection for remote support.
Built in Abruzzo. Working on several continents.
EMG is a family manufacturer with four generations of industrial tradition, based on the Adriatic coast of Italy. Its SLP machines produce cages for bridges, railways, ports, industrial facilities, energy developments and deep foundation works.
Welding standards
MIG welding process with PLC-managed parameters, in compliance with EN ISO 17660 and AWS D1.4.
The engineer answers
A lean company: the engineer who designs the machine installs it and stays available.
