Representative image10 Crane Zones, One Turnkey System, One Month Early
Overhead cranes for every production, inspection and support area of a new jet engine component plant, released to production ahead of a fixed contract date.
A Tier-1 aerospace manufacturer was opening a new plant for high-value rotating jet engine components. It needed overhead cranes in 10 separate zones, all ready by a fixed December 31 commissioning date.
Han-Tek engineered, built, installed, tested and documented every crane as one turnkey system under one project manager. The cranes were released to production on November 29, 32 days ahead of the contract date, and the customer came back for more crane work in later years.
Ten crane systems, one opening date
The plant needed lifting in every area where engine components are machined, measured and stored. Each zone had its own layout and its own runway, but all of them had to be running before the plant opened.
Ten different zones
Four production zones, three CMM inspection rooms, and dedicated cranes for calibration, maintenance and stores.
A date that could not move
Commissioning was fixed at December 31, and the install could not slow the rest of the plant ramp-up.
A secure site
An ITAR-controlled plant wanted one accountable supplier for engineering, install and turnover.
One supplier for every zone
- Designed and built single-girder bridges in-house, each with an R&M 2-ton electric chain hoist.
- Added Telemotive laser anti-collision on every bridge so cranes sharing a runway can't run into each other.
- Used variable-frequency drive (VFD) bridge control for smooth starts and stops around high-value parts.
- Delivered it turnkey: engineering, procurement, fabrication, about 8 weeks of install, OSHA-required 125% load testing, operator training and turnover documents.
- Stocked a critical-spares package on site from the day the order was placed.
| Bridge speed | 120 fpm max, VFD control |
|---|---|
| Trolley speed | 80 / 20 fpm, two-speed |
| Hoist | R&M 2-ton electric chain, 16 fpm |
| Power | 460 V, 3-phase, 60 Hz |
| Standard | CMAA Class C, indoor service |
Released a month ahead of the contract date
- Nov 29, 2010Released to production
All crane systems handed over and running.
- Dec 3, 2010Final documentation delivered
Manuals and turnover documents in the customer's hands.
- Dec 31, 2010Contract deadline
The fixed commissioning date, beaten by 32 days.
- Ahead of schedule: released to production 32 days before the contract date.
- No disruption: the 8-week install ran on schedule without slowing the plant ramp-up.
- Built to last: the systems remain in continuous service.
- Repeat business: the customer came back to Han-Tek for more crane work at the same plant in later years.
Questions about multi-zone crane projects
Can one supplier handle cranes for an entire new plant?
Yes. On this project Han-Tek handled engineering, fabrication, install, load testing, training and documentation for all 10 zones under one project manager.
How do cranes on a shared runway avoid collisions?
Each bridge here has a Telemotive laser anti-collision system that slows and stops a crane before it reaches another one.
Does Han-Tek work in ITAR-controlled facilities?
Yes. This plant is ITAR-controlled, and Han-Tek engineered, installed and turned over the full crane system there.
