Electric vs diesel spider crane: which do you need?
Updated 2026-11-06 · BAJUN Machinery
Use the electric motor for indoor work, where exhaust and noise are a problem and mains power is available. Use the diesel engine outdoors or on sites without power. Most of our spider cranes carry both, so one machine covers both kinds of job.

When the electric motor is the right choice
Shopping centres, airports, hospitals, food plants and occupied offices usually do not accept diesel exhaust indoors. An electric motor also reduces noise for work in occupied buildings.
When you need the diesel engine
On building sites, yards and outdoor jobs there is often no reliable power supply near the lift point. The diesel engine makes the crane independent of mains power.
