Narrow Access Crane Erection for Steel Structures in Bali: Maneuvers in Canggu & Ubud

Projects in Canggu, Ubud, and elsewhere in Bali need checks of the actual route.

Projects in Canggu, Ubud, and elsewhere in Bali need checks of the actual route.

1. Survey the vehicle route, not one minimum road width

Projects in Canggu, Ubud, and elsewhere in Bali need checks of the actual route. Record clear width, bends, gradients, cables, gates, obstructions, and the capacity of bridges or drain covers. No single road width guarantees access for every truck or crane. The fleet provider assesses vehicle envelopes, swept paths, and exit routes.

2. Lifting capacity follows charts and configuration

A “25-ton” or “50-ton” crane label is not its capacity at every radius. The equipment provider checks the model-specific load chart for boom length, counterweight, outriggers, radius, working direction, and actual conditions. Component weight, rigging, hook block, and manufacturer restrictions are considered for the configuration. Do not convert nominal capacity into site capacity without these checks.

3. Crane support and the lifting plan

Review ground bearing, excavations, drainage, buried utilities, and support reactions. Mat or pad sizes do not come from one table for all cranes. The lift plan addresses the load path, lift points, rigging, exclusion zones, communication, weather, and personnel responsibilities. Temporary structural stability during erection also requires review.

4. Modular deliveries and access coordination

If full-length segments do not suit the route, plan delivery lengths and site connections with the designer and fabricator. Splices, bolts, and welds follow design rather than universal plate thicknesses or torque. Confirm arrangements with owners, road managers, and local parties; nighttime mobilization rules or community approval durations are not uniform across sites.

5. Pre-mobilization checklist

Keep the route survey, fleet confirmation, component weights, load charts, lifting plan, support checks, and access arrangements. Report new fences, excavations, or nearby activity before equipment departs. Prices, delays, and erection durations depend on project scope rather than unverified incident figures.

Project questions

Can these details be used directly for any project?

No. Sections, connections, methods, and inspection criteria must follow the project design, specified standard editions, and relevant product data.
