Link-Belt crawler crane on documented bridge lift case study

Case Studies From Live Crane & Excavator Projects

Each Link-Belt case study records lifting capacity used, boom length configuration, excavator cycle times, undercarriage hours, and customer feedback after commissioning. Review the operating parameters before you size your next fleet order.

Documented Jobsite Outcomes

On a Southeast Asian viaduct, one lattice boom crawler crane placed 288 precast segments across a rainy-season window. Lift plans listed radius, hoist speed, and wind limits for every pick. The superintendent reported zero rework on segment seating after the final survey.

"The published load chart held up across the whole rainy-season lift window — we never had to reconfigure the boom mid-contract." — Lifting Superintendent, 288-segment viaduct

At a limestone quarry belt, forty-two hydraulic excavators ran mass excavation with 1.6 m³ heavy-duty rock buckets. Digging depth targets and breakout force settings were logged against geotech layers. ISO 4406 hydraulic cleanliness sampling caught pump wear before an unplanned shutdown.

A coastal power-plant module set used telescopic cranes with verified ground pressure mats on soft fill. Operating weight and outrigger loads were checked against the pad design before the first module left the barge.

Urban demolition crews paired high-reach excavators with dust-suppression kits. Attachment pin inspections between 22-story decommission cycles kept boom geometry within the manufacturer envelope while cycle times stayed predictable for the recycling haul fleet.

Operating Boundaries We Disclose Before Mobilization

Case studies succeed inside published envelopes. Outside these limits Link-Belt will refuse a lift or excavator configuration rather than stretch a load chart:

Wind and radius: Segment picks above the charted wind speed or outside the approved boom length / radius pair are stopped until the engineer of record revises the ASME B30 or AS 2550 plan.
Ground pressure on soft fill: Telescopic and crawler cranes need mat designs that keep calculated ground pressure within the pad rating; soft coastal fill without mats is not a supported configuration.
Hydraulic cleanliness: Main-pump warranty on quarry excavators assumes ISO 4406 sampling on the stated interval; skipped filtration voids the cleanliness claim even if digging depth targets were met.
Heat and altitude packages: Hydraulic system pressure stability above 40 °C ambient or above the altitude listed on the serial plate requires the heat/altitude kit before we certify cycle-time guarantees.

How to Read a Link-Belt Case Study Pack

What parameters appear in every lift case study?

Lifting capacity at working radius, boom length and jib configuration, hoist speed averages, ground pressure assumptions, and the standard used for the signed lift plan (ASME B30 or AS 2550).

Do excavator cases include undercarriage data?

Yes. Track shoe width, operating weight, ground pressure, and hours since last undercarriage rebuild are listed so fleet managers can compare sites with similar soil conditions.

Can we request video and customer references?

Project videos and reference contacts are available for released case studies after a short NDA when the owner requires confidentiality on plant coordinates.

How current are the case study metrics?

Metrics refresh when the project closes or when a major mid-contract configuration change is approved by the engineer of record.
