Shanghai Gerunwan Technology Co., Ltd. (GRWT) has air-freighted the second batch of running-gear components for the quay-crane renewal programme at a container terminal in Panama at the Pacific entrance of the Panama Canal — flying the consignment out, as with the first batch, to put the wheels in the terminal's hands at the earliest possible date.
This second lot supplies the complete running gear for the second Hyundai quay crane — 26 sets in three reinforced export wooden cases, 2,205 kg gross (net 2,160 kg) — the identical scope and quantity as the first lot delivered in September. Together, the two air shipments complete all 52 sets required for the terminal's two Hyundai cranes.
Trolley Wheel Assemblies — 4 sets
Trolley Side Rollers + C-Trolley Wheels — 12 sets
C-Trolley Wheels + Bottom Side Roller Assemblies of C-Trolley — 10 sets
Total: 26 sets in 3 export wooden cases · Gross 2,205 kg · Net 2,160 kg
Transport Mode: Air freight — the fastest route to the terminal
Packing List: PL-GRWT26092501 · Order GG26071403 ·
Three reinforced export cases at GRWT's Shanghai workshop — 26 sets, 2,205 kg gross, ready for air freight.
The second Hyundai crane is also down for overhaul, and every day it waits costs the terminal production capacity. GRWT's machining, assembly, painting and packing teams worked overtime through the final stages so the lot could be released ahead of the originally planned despatch window — and as with the first batch, the consignment was booked on air freight rather than ocean, cutting weeks of transit time and moving the wheels into the customer's hands while the crane is still out of service.
The three cases were marked BOX 1 / BOX 2 / BOX 3 with GRWT shipping marks stencilled on two opposite sides, steel-strapped and secured for long-distance export. Rollers and matching hardware were laid in layered compartments with bubble wrap, cardboard bracing and dunnage to eliminate any movement in transit.
Every component passed the same inspection route as the first shipment: dimensional inspection of each machined wheel, roller, shaft and spacer before painting; verification of the painted surfaces with a digital coating-thickness gauge, with readings of around 300 µm confirming the marine-grade protective coating for the tropical, high-humidity environment of the Panama Canal zone; and a final fit-and-check of each completed assembly — shafts, bearings and bolted flange hubs — before preservation and packing.
The programme covers 116 sets of running gear in total — 52 sets for the two Hyundai cranes, now complete across the two shipments, and 64 sets for the two ZPMC QC25/QC26 cranes. The remaining ZPMC trolley wheels and rollers are already in production at GRWT's workshops and are scheduled to be despatched in mid-October 2026.
This project again demonstrates GRWT's full-process, turn-key capability: on-site surveying and measurement → drawing design → manufacturing → quality control → export delivery to the terminal → coordination with the site construction crew for on-site installation and modification. With no complete original drawings available for these decades-old Hyundai and ZPMC QC cranes, GRWT's engineers surveyed and measured the running gear at the terminal and consolidated the full manufacturing drawing set (HYPPC / ZYPPC series) from actual on-site conditions — the critical first step that guarantees drop-in interchangeability with the original parts.
GRWT specializes in reverse-engineering and remanufacturing spare parts for legacy port equipment, including ZPMC, Hyundai, Konecranes, Noell and other crane makes, with proven deliveries to terminals across Latin America, Asia, Europe, the Middle East and Africa.
