In the bustling ports and vast oceans, ship deck cranes are the core equipment that ensures efficient cargo loading and unloading as well as flexible material hoisting. Among them, Electrical Hydraulic Cranes and Hydraulic Cranes have become the “main players” on ship decks thanks to their powerful performance. As a leading manufacturer in the industry, MAXTECH's series of products have fully utilized the technical advantages of these two types of cranes, providing reliable support for maritime operations around the world.
Electrical Hydraulic Cranes: The Perfect Blend of Precision and Efficiency
Electrical hydraulic cranes combine the precise control of electric drive with the strong power of hydraulic systems. Their working principle involves an electric motor driving a hydraulic pump to convert electrical energy into hydraulic energy. This hydraulic energy then acts on hydraulic cylinders or motors to move the ship crane's arm, enabling lifting, lowering, rotation, and other operations. MAXTECH's electrical hydraulic cranes are equipped with advanced variable - frequency control technology, which can automatically adjust the motor speed according to the load, ensuring stable operation while reducing energy consumption.
Take the MAXTECH EHC - 800 series as an example. This model has a maximum lifting capacity of up to 80 tons and is suitable for various ships, including container ships and bulk carriers. In actual operations, its intelligent control system can achieve millimeter - level positioning accuracy. Even in windy and wavy conditions, it can accurately grasp and place containers. Additionally, this series of cranes is equipped with a remote monitoring system. Operators can use a terminal to view the equipment status in real - time, and the system can issue early warnings for potential faults, significantly improving the reliability and maintenance efficiency of the equipment.
Hydraulic Cranes: The Pure - powered Titans of the Ocean
Hydraulic cranes, on the other hand, are centered around a pure hydraulic system. They directly use the high - pressure oil generated by the hydraulic pump to drive the actuators, eliminating the need for an electrical - hydraulic conversion process. This design gives hydraulic cranes the characteristics of a simple structure, rapid response, and powerful performance, making them especially suitable for scenarios that require extremely high lifting capacities and operate in harsh environments.
The MAXTECH HC - 1200 heavy - duty hydraulic deck crane is a prime example. Specifically designed for marine engineering vessels and heavy - duty port lifting, it has a maximum lifting capacity of over 120 tons. It adopts a dual - pump dual - circuit hydraulic system, which can provide stable power output even in complex sea conditions. In an offshore wind power installation project, the HC - 1200 crane easily lifted wind turbine towers weighing dozens of tons. Even when faced with strong wind interference, it maintained stable lifting operations due to the rapid response of the hydraulic system, completing the installation tasks efficiently. Moreover, the modular design of hydraulic cranes makes maintenance more convenient. MAXTECH has also applied an anti - corrosion coating to effectively extend the equipment's service life in high - salt - fog marine environments.
How to Choose: Requirements Dictated by Scenarios
Electrical hydraulic marine cranes and hydraulic ship deck cranes each have their own strengths, and the choice of ship operators usually depends on actual operational needs. Electrical hydraulic cranes are more suitable for routine cargo handling tasks that require high precision, energy efficiency, and automation, such as container transportation and general bulk cargo handling. Hydraulic cranes, with their powerful performance and ability to withstand harsh environments, have the edge in marine engineering, heavy - equipment lifting, and other fields.
As a technological team in the industry, MAXTECH is always committed to providing customized solutions for customers. Whether customers need the precise and efficient electrical hydraulic cranes or the extremely powerful hydraulic cranes, MAXTECH can rely on its extensive product line and professional technical team to safeguard maritime operations. As the shipping industry evolves towards greater intelligence and sustainability, these two types of deck cranes will continue to be upgraded. Driven by companies like MAXTECH, they will continue to inject new vitality into global trade and marine engineering.
