About our telescopic boom marine cranes

A telescopic boom marine crane extends a straight boom in sections to reach from the deck to the quay or another vessel. It is a simple choice for regular lifts of cargo and equipment where a direct reach matters more than folding away.

BOB-LIFT offers telescopic boom marine cranes in 10 capacity classes from 2 t to 20 t: 2, 3.2, 4, 5, 6.3, 8, 10, 12, 16 and 20 t. Model codes include the SQ3.2SA3T, SQ5SA3T, SQ6.3SA3T, SQ8SA4T, SQ10SA5T and SQ12SA5T. Each crane runs every boom and slewing motion on a deck-style test stand in Xuzhou before release, and our ISO 9001 certificate covers marine crane production.

Size the crane from the heaviest load at the longest outreach, not from the rated capacity alone. Read the load chart for that radius, then check that your deck can carry the crane and that the vessel's hydraulic supply suits it. If deck space is tight and the boom must fold away, compare our knuckle boom marine cranes.
