Match lifting capacity, boom length and outrigger footprint to your pour schedule — from high-rise tower crane cycles to 250–650 t crawler tandem lifts on bridge segments.
Answers our field advisors give when contractors compare crane duty cycles, concrete pump output and excavator undercarriage wear before issuing a PO.
Yes. Anti-two-block and load-moment indicators ship on every tower, mobile and crawler crane from our CE-marked lines, aligned with ASME B30 practice and site lift-plan audits.
Share floor cycle, tip-radius loads and free-standing height. We map jib length, hoist speed (m/min) and counter-jib clearance so the crane clears adjacent towers without mid-project re-rig.
Clay often runs 110–115% fill; crushed aggregate closer to 90–95%. We tune cycle time and breakout force during commissioning so your dig depth targets stay realistic.
Crawler units win on soft ground and deep digs with lower ground pressure (kPa). Wheeled excavators cut trailer moves on paved streets. We compare gradeability and final-drive duty against your haul plan.
Provide vertical height, pipe diameter and target output capacity (t/h). We recommend boom or line-pump configurations and verify hydraulic system pressure so the pour crew hits floor cycles without pipe surge.
Undercarriage groups are quoted with hours-or-months coverage — typically 3,000 hours or 18 months, whichever comes first — logged against serial numbers in our parts hubs.
Four capability stories our advisors walk through with fleet managers before locking a crane or excavator package.
Main pumps and pilot pressure circuits are factory-flushed and sampled to ISO 4406 targets before shipment. On commissioning, our FSEs log particle counts so slew and hoist circuits stay within the cleanliness band that protects valves during long boom cycles.
Mobile cranes and excavators destined for EPA or EU Stage V sites ship with DPF + SCR aftertreatment and in-cab DEF alarms. We attach emissions documentation to each serial so procurement can paste it into tender binders without chasing dealers.
Track shoe width, sprocket hardness and roller seals are specified for multi-shift quarry and earthworks duty. Rebuild kits target roughly 8,000-hour intervals so equipment managers can schedule downtime beside planned liner changes.
With plants totaling about 450,000 m² and fleets shipping roughly 8,000 units a year, Zoomlion keeps regional hubs stocked for hydraulic kits, boom pins and pump wear parts. Contracted sites target under 18-hour mean time to repair on critical machines.
Illustrative grouped table our advisors use when comparing boom length, lifting capacity and emissions packages for a bridge precast tender.

"Commissioned two tower cranes for a 36-floor core in 9 days — tip-radius loads matched the pour schedule without a mid-build jib change."
"Their team re-certified our 250-ton crawler on-site in five working days. Zero downtime on the bridge segment lifts that week."
"Concrete pump boom package hit the vertical height we specified; hydraulic pressure stayed stable through 14 continuous floor cycles."
Share company, country, equipment class and fleet size — advisors reply with a package outline in two working days on typical inquiries.
