EQUIPMENT FEATURE: ROYAL CARGO’S DIFFERENT TYPES OF CRANE

12 Sep, 2019 by Jill Viray

Cranes are essential for heavy construction work and lifting tasks of all kinds.

Equipped with cables and pulleys and based upon the application of fundamental mechanical principles, a crane can lift and lower loads well beyond the capabilities of human construction workers.

Crane design has evolved to meet the demands of a variety of industrial needs, and modern cranes often coordinate simple systems to achieve complex lifting tasks.

How does it work? A crane is able to lift objects because the load is offset by counterweights which stabilize the crane, allowing it to lift and move its load.

The following are the different types of crane that Royal Cargo has:

• Crawler Crane

A special type of mobile crane fitted with caterpillar tracks, the crawler crane can be used on soft and boggy ground where wheeled vehicles would be unable to operate.
This crane is generally very stable because its broad base and tracking spreads the weight over a wide area.
This sturdy equipment is useful on construction sites during the initial phase of building projects where its ability to move heavy loads over areas of soft soil is a particular asset.

• Mobile Crane

A mobile crane is the most standard and versatile type of crane. It is a cable-controlled crane commonly mounted on wheeled vehicles. It is designed to easily transport to a site and use with different types of load and cargo with little or no set-up or assembly.

The mobile crane consists of a steel truss or telescopic boom mounted on a mobile platform, which could be a rail, wheeled, or even on a cat truck. The boom is hinged at the bottom and can be either raised or lowered by cables or hydraulic cylinders.

There are four principal types of mobile cranes: the truck mounted, rough-terrain, crawler, and floating.

Royal Cargo owns two types of mobile crane: the rough terrain crane and the all-terrain crane.

1) Rough Terrain

A rough terrain crane has a boom mounted on an undercarriage atop four rubber tires that is designed for off-road pick-and-carry operations. Outriggers are used to level and stabilize the crane for hoisting. These telescopic cranes are single-engine machines, with the same engine powering the undercarriage and the crane, similar to a crawler crane. The engine is usually mounted in the undercarriage rather than in the upper, as with crawler crane. Most have 4-wheel drive and 4-wheel steering for traversing tighter and slicker terrain than a standard truck crane, with less site prep.

2) All Terrain

An all-terrain crane is a hybrid combining the road ability of a truck-mounted and on-site maneuverability of a rough-terrain crane. It can both travel at speed on public roads and maneuver on rough terrain at the job site using all-wheel and crab steering.
