Link-Belt 355 X4S: What a Minimum Swing Radius Excavator Is Built For
TL;DR: The Link-Belt 355 X4S is Link-Belt’s largest minimum swing radius (MSR) excavator, built to rotate a full 360 degrees without the tail swinging out past the tracks. At roughly 78,709 lbs with a 205 HP engine, it’s built for demolition, sorting, and utility work in tight urban or industrial sites where a standard excavator’s tail swing would be a problem.
What Is a Minimum Swing Radius Excavator?
A minimum swing radius (MSR) excavator keeps its counterweight and upper structure compact and close to the tracks, so the machine can rotate a full 360 degrees without the tail swinging out past the width of the tracks. On a standard excavator, the tail swings well beyond the tracks during rotation, which can be a problem on sites tight against buildings, walls, fences, or other equipment. The 355 X4S is Link-Belt’s largest MSR model, giving contractors the power of a large excavator without that wider swing footprint.

What Is the 355 X4S Built For?
Link-Belt designed the 355 X4S for road construction and maintenance, residential and commercial excavation, site prep, pipeline construction, sewer and utilities work, and demolition projects. Its shortened tail swing gives it the versatility to work in spaces a standard large excavator can’t, without giving up the power and lift capacity of a bigger machine.
- Demolition: the grapple attachment shown here is suited to sorting and clearing demolition debris
- Utility and pipeline work: tight swing clearance matters when working alongside existing infrastructure
- Lifting mode: a lower-rpm power boost is available for crane-style lifting tasks
Cab and Operator Features
- Full-size cab with more headroom and legroom than the previous MSR generation
- High-back air suspension seat with heat and tilt functions
- On-screen climate controls, onboard Bluetooth, and a 10-inch LCD monitor
- Two standard high-resolution cameras, one at the rear and one on the right side, viewable together on the monitor
Frequently Asked Questions
What does "minimum swing radius" actually mean?
It means the excavator’s tail doesn’t swing out past the width of its tracks when it rotates, unlike a standard excavator whose counterweight extends well beyond the tracks during rotation.
Is the 355 X4S a long reach excavator?
No. It’s built for tight swing clearance rather than extended reach, and its 34-foot-8-inch reach at ground level is well short of a dedicated long reach machine’s 60-plus feet.
