The Singapore construction, shipbuilding and logistics sectors are based on heavy lifting. In order to move large volumes of loads safely and efficiently, companies use portal cranes, sometimes called Goliath cranes or gantry cranes. The cranes are to carry, transport and swing heavy elements whereby the tower crane or overhead crane may not be feasible.

Portal cranes in Singapore, be it in the shipyards, ports, or warehouses, offer the lifting capacity and versatility that ensure that the industrial processes continue to run.

What Are Portal Cranes and Their Key Uses?

A portal crane is a type of crane with a bridge supported by two or more legs that run on rails or wheels. The terms Goliath crane and gantry crane are often used interchangeably, though some industries may use “Goliath” to describe very large gantry cranes with extremely high capacities.

These cranes are widely used across multiple sectors. In shipyards, they lift hull sections, ship engines, and other massive components. In warehouses, they move bulky or oversized goods efficiently. At ports, they handle the loading and unloading of containers, while at construction sites, they lift steel structures, precast beams, and heavy machinery. In addition, mobile portal cranes provide flexibility for projects that require frequent relocation, offering an alternative to fixed installations.

Types of Portal Cranes in Singapore

Single Girder Portal Cranes

These cranes are compact and cost-effective, designed for lighter loads typically ranging from 5 to 20 tonnes. They are commonly used in workshops and logistics facilities where space and lifting needs are modest.

Double Girder Portal Cranes

Built with two girders for added strength, double girder portal cranes can handle between 50 and 200 tonnes. They are ideal for shipyards, ports, and other heavy-duty applications that require longer spans and wider coverage.

Mobile Portal Cranes

Mobile cranes are designed for flexibility and portability, making them suitable for construction projects with shifting work areas. Their ability to move quickly between sites adds to their efficiency.

Semi-Goliath Cranes

Semi-Goliath cranes are supported on one side by a building structure and on the other by rails. This design makes them a space-saving and efficient solution for workshops or production plants with limited layouts.

Frequently Asked Questions (FAQ)

Q: What is the difference between a portal crane and an overhead crane?

A: An overhead crane is fixed within a building structure, running on elevated tracks across the ceiling. A portal (gantry/Goliath) crane, on the other hand, is supported by legs that run on rails or wheels, making it more versatile for outdoor and large-scale applications.

Q: How do you maintain a portal crane?

A: Regular inspections, lubrication of moving parts, timely replacement of worn components, and adherence to MOM’s safety inspection schedule are essential. Partnering with suppliers that offer maintenance services ensures cranes remain safe and efficient over time.

Final Thoughts

Portal cranes (Goliath/gantry cranes) are present at every corner of the industrial sector of Singapore, shipyards, and construction sites alike. They have the capability of transporting huge loads in an efficient manner, and this makes them a pillar in heavy lifting services.

Businesses ought to seriously consider the type, load capacity, and technical specifications needed for projects when settling on a portal crane. Cooperation with trusted suppliers will provide not only the necessary equipment but also safe and stable operations.

To reach a goal of streamlining their operations, the first step that companies should follow in order to find a custom crane solution to their problems is consultation with suppliers in Singapore, as the country has high industrial standards.
