Guide to Telescopic Cranes

What are Telescopic Cranes?

Telescopic cranes, also known as boom cranes or hydraulic cranes, are distinguished by their telescoping boom. This feature allows the boom to extend and retract, similar to a telescope, providing unparalleled reach and versatility in lifting operations.

Mechanics Behind Telescopic Cranes

Hydraulic Cylinders

The core mechanism of telescopic cranes relies on hydraulic cylinders. These cylinders act as the “muscles” of the crane, expanding and contracting in response to hydraulic pressure. When the operator activates the crane’s controls, hydraulic fluid is pumped into these cylinders, causing them to extend or retract the boom[1][5].

Boom Structure

The boom itself is composed of multiple sections, often referred to as “telescopes,” which can be hydraulically extended or retracted to achieve the desired length. This modular design enhances the crane’s lifting capabilities and facilitates ease of transportation and maneuverability on the job site[1][3].

Features of Telescopic Cranes

Guide to Marine Pedestal Cranes

Overview of Marine Cranes

Marine pedestal cranes are critical components of maritime operations, used for a variety of tasks including cargo handling, maintenance, and supply operations on ships, barges, and offshore platforms. These cranes are designed to operate efficiently and safely in the challenging marine environment.

Components of a Marine Pedestal Crane

Foundation and Pedestal

• Foundation: The foundation of a marine crane provides stability and contains critical components. It is securely fixed to the deck of the vessel or barge[1][4].
• Pedestal: The pedestal is a circular cross-section welded structure that bears all vertical forces, radial forces, and overturn moments of the crane. It is made from high-strength marine-grade steel to withstand saltwater corrosion, wind, and waves[1][4].

Slewing Mechanism

• The slewing mechanism, located inside the pedestal, enables the crane to turn 360 degrees. This mechanism uses powerful hydraulic motors or electric drives to ensure smooth rotation[1][4].

Tower Body

• In larger cranes, a tower body is mounted above the pedestal. This vertical post increases the height and range of the crane, allowing it to lift heavier loads over longer distances. The tower often uses lattice work made of steel beams for flexibility and balance between weight and strength[1][4].

Crane Boom

• Types of Booms:
• Fixed Boom: A fixed boom has an unchangeable length and lifting capacity, commonly used on certain ship cranes[1].
• Telescopic Boom: A telescopic boom has nested parts that can be extended hydraulically and contracted, making it adaptable for different ship sizes and port operations[1].
• Knuckle Boom: This type of boom can fold and extend, saving space on board and offering flexibility in cargo handling[4].
• The boom is connected to the tower body via a boom shaft and may include a sheave block at the boom head for hoisting operations[4].

Hoisting Winch

• The hoisting winch is mounted on the main boom and is equipped with a hydraulic motor, reducer, brake, bearing support, drum, and frame. It features a reliable mechanical braking system with low-speed stability and high transmission efficiency[4].

Slewing Mechanism and Rotation

• The slewing mechanism, consisting of a hydraulic motor with planet reducers, brakes, and transmission pinions, controls the slewing speed of the crane. It engages with the inner gear of the slewing bearing to drive the crane to rotate 360 degrees[4].

Operating Platform and Control System

• An operating platform is mounted on the side of the tower body, providing the operator with a clear view of the hook movement and surrounding conditions. The control system includes operating handles and remote control options to manage hoisting, luffing, and telescopic movements[4].

Oil Pump Unit and Hydraulic System

• The oil pump unit, consisting of a marine electric motor, pump, and coupling, provides hydraulic oil for the crane’s hydraulic system. It is designed to prevent damage and ensure smooth operation[4].

Stability and Safety Features

Counterbalance

• A counterbalance, typically made of concrete or steel blocks, is placed at the back of the crane to balance the weight of the boom and the lifted goods. This ensures that the crane does not tip over and maintains a safe center of gravity[1].

Sway Control

• Sway control systems use hydraulic actuators and sensors to detect and counteract any swinging motion of the boom arm and payload. This ensures smooth and safe lifting operations even in tough sea conditions[1].

Active Heave Compensation (AHC)

• AHC technology is used in some marine cranes, especially in offshore operations, to compensate for the vertical movement of the crane due to wave action. This enhances the precision and safety of lifting operations[3].

Applications and Variations

Marine, Offshore, and Wind Cranes

• Marine cranes are used on various vessels such as merchant ships, cargo vessels, cruise vessels, ferries, and yachts. They are also employed in the aquaculture market and on governmental vessels[2].
• Offshore cranes are designed for operations on oil and gas platforms, wind farms, and other offshore installations. They include rope luffing lattice boom cranes, knuckle boom cranes, and stiff boom cranes[2][3].
• Wind cranes are specialized for the offshore wind industry, featuring compact designs and high lifting capabilities[2].

Specific Crane Types

• Foldable Knuckle Boom Cranes: These cranes save space on board and are versatile in cargo handling[2].
• Telescopic Boom Cranes: Ideal for port operations where adaptability to different ship sizes is necessary[1].
• Wire Luffing Lattice Boom Cranes: Used for heavy lifting in offshore environments[3].

Conclusion

Marine pedestal cranes are sophisticated pieces of machinery that play a crucial role in maritime and offshore operations. Their design incorporates various components and technologies to ensure stability, safety, and efficiency in challenging marine conditions. Understanding the structure and functionality of these cranes is essential for their effective use and maintenance.

What are the different types of pedestal cranes available?

There are several types of pedestal cranes available, each designed to meet specific operational needs. Stationary pedestal cranes are mounted on a fixed pedestal and are used where continuous lifting tasks with high weights are required. Movable pedestal cranes, on the other hand, offer mobile capability, making them suitable for situations where lifting tasks need to be carried out between different sites. Pedestal offshore cranes are specifically designed for long-lasting endurance in harsh offshore applications. Additionally, pedestal jib cranes feature a vertical pedestal or column supporting a horizontal jib arm, which can rotate to provide lifting and maneuvering capabilities in a limited area.

What safety measures are integrated into pedestal cranes?

Pedestal cranes are engineered with multiple safety measures to ensure safe and reliable operation. One of the key safety features is the Overload Protection System (OPS), which minimizes the risk of structural failure or accidents by preventing the crane from lifting loads beyond its rated capacity. The Anti Two Block (ATB) device is another critical safety feature that prevents crane damage by ensuring that the hook block does not come into contact with the crane’s boom tip. Additionally, these cranes are designed with operator safety in mind, featuring operator cabs that provide a wide view of the surroundings and are equipped with safety and comfort amenities. The cranes are also built to withstand harsh environmental conditions, including high winds and corrosive environments, further enhancing their safety profile.
