EMG S.r.l. · Specialists in pile cage machines
The SLP series welds the reinforcement cages of foundation piles, from Ø100 to Ø3000 mm, up to 24 m long and over 30 t. Tell us your cage in three numbers. You see your machine take shape, and our technicians reply with model, layout and production estimate.
Build your SLP
Four steps. No price list, because the price follows your configuration. At the end, the people who build the machine take over.
Drag to your diameter. The model picks itself, and we tell you when a size up is worth it.
Not sure about the numbers? Skip the steps and send the drawing.
Four checks we make before quoting. If one of them needs a bigger frame, we move you up and tell you why. If it needs a part, we add it to your configuration.
The same PLC, interface and recipes on every model. These choices shape your cycle and your layout.
Your configuration goes to EMG, not to a sales inbox. Our technicians check it against your cages and reply with the exact model, the layout drawing and a production estimate.
No price list, no newsletter. Our technicians reply about your cages.
A pile cage machine builds the steel cage that reinforces a foundation pile. People also call it a rebar cage machine or a pile cage welding machine. The name changes, but the job stays the same.
The machine holds the longitudinal bars at both ends and rotates the cage. A welding head fixes the spiral wire to each bar. The result is a straight cage with a constant spiral pitch, ready to be lifted into the bore.
These cages serve bored piles, CFA piles and drilled shafts. They go into bridges, metro lines, ports, energy plants and data centers.
The same weld time on every crossing, whatever the rotation speed. Held by the PLC.
Welding parameters saved per cage type and recalled by the operator or by barcode.
Parameters set and checked against a preset window during production.
A reference-scale disc places the bushes; the PLC guides the operator step by step.
All six models share PLC control, stored recipes, the same interface and common spare parts. What changes is the cage envelope.

The SLP uses a heavy steel frame designed for continuous industrial work. Direct-drive technology moves the master and slave heads. Dual rack-and-pinion carriages guide the bars with precision.
On the SLP 3000, the reinforced lifting system handles cages over 30 t. Optional roller conveyors move bars up to Ø40 mm and reduce operator effort.
The modular design lets you install the machine inside a plant or directly on the project. Therefore you reduce the transport of finished cages.
The machine ships in containers. We install it, commission it and train your operators on site, and we support the machine online for diagnostics and remote assistance.
We prefer to say it early.
Your cages exceed Ø3000 mm, or your bars exceed Ø55 mm: the SLP range does not cover them. You need a single cage: a machine pays back through series production, not through one-off jobs. Your design needs a geometry other than the welded spiral cage: send the drawing and we tell you straight.
In every other case, three numbers are enough to start.
EMG S.r.l. is an Italian company focused on rebar cage machines. Pile cage machines are the core of its work.
The owners inherit four generations of experience in machine building. The people at EMG are the ones who have innovated pile cage machines over the last 20 years. As a result, EMG works as a specialist, not as a generalist.
EMG machines already serve leading foundation contractors on several continents. EMG sells and supports the SLP machines together with Schilt Engineering. About the company →
A pile cage machine welds the reinforcement cages used in foundation piles. The cage rotates and the welding head fixes the spiral to every longitudinal bar. The result is a straight, repeatable cage.
In practice, yes. Both names describe a machine that builds welded reinforcement cages. "Pile cage machine" points to cages for foundation piles, the focus of the EMG SLP series.
The range goes from Ø100 mm (SLP 650) up to Ø3000 mm (SLP 3000). Cage length reaches 24 m, and the SLP 3000 handles cages over 30 t.
The largest cage you produce decides. Then check the thickest bar, the spiral wire and the cage weight. Bars above Ø40 mm or cages above 14 t point to the SLP 3000. Ø40 mm bars on the SLP 1200, 1500 and 2000 only need larger bushings, and Ø20 mm spiral needs dedicated rollers. The configurator above does these checks for you.
The price follows the configuration: model, number of torches, roller conveyors, layout, installation and training. EMG quotes after seeing your cages, so you pay for the machine you need.
Output depends on diameter, number of bars, spiral size and pitch. As one measured example, an SLP 650 produced a Ø350 mm cage of 16 m with eight Ø25 mm bars in 9 minutes. That is about 16 cages per 8-hour shift. Send your cage drawing for an estimate on your configuration.
Yes. The modular machine works inside a plant or directly on site. You need a covered area with a level floor, a power supply to EMG specification and a crane sized for your cages.
We train your operators on site. After commissioning, the machine stays connected for remote diagnostics.
Three numbers. Our technicians.
Diameter, bar size, cage length. You see the model take shape, and we reply with the layout and a production estimate for your cages.
