Standard Explosion-Proof Jib Crane for Crude Oil, Product & Chemical Tanker Decks

30 Jun,2026

Decks of crude oil tankers, product tankers and chemical carriers are classified as flammable and explosive hazardous zones. The atmosphere filled with volatile oil gas imposes mandatory explosion-proof specifications for all deck lifting equipment.

Introduction
Decks of crude oil tankers, product tankers and chemical carriers are classified as flammable and explosive hazardous zones. The atmosphere filled with volatile oil gas imposes mandatory explosion-proof specifications for all deck lifting equipment.

To address general operational demands of liquid cargo vessels including compact deck layout, explosion-proof compliance and marine anti-corrosion performance, Kuli Machinery has launched an explosion-proof jib crane tailored for tanker deck service. This model integrates and implements standard technical requirements covering explosion-proof criteria, marine anti-corrosion treatment and load self-locking against vessel rolling, delivering standardized lifting supporting solutions for new shipbuilding and vessel retrofitting projects.
General Operating Limitations for Tanker Deck Equipment
Mandatory explosion-proof compliance
Flammable oil vapors persist on liquid cargo vessel decks. Conventional lifting cranes equipped with electric motors or regular hydraulic assemblies may generate electric sparks or high-temperature surfaces, failing to meet ATEX, IECEx and classification society Zone 2 standards. Explosion-proof lifting units are therefore compulsory.
Severe marine corrosion conditions
Exposed open decks are subject to heavy salt spray year-round. Standard industrial explosion-proof equipment without marine-grade anti-corrosion coating will suffer rapid corrosion of steel structures and sealing components during long-term offshore service.
Restricted deck space
Tanker decks are densely arranged with pipelines and valves, calling for compact crane designs. Additionally, mechanical self-locking structure is required to prevent load sliding when the vessel rolls.
Dual certification threshold
Equipment must satisfy both marine classification society rules and international explosion-proof standards. Qualified deck cranes with dual certification are relatively limited on the market.
