Marine stiff boom cranes play a pivotal role in the maritime industry. Renowned for their sturdiness and reliability, they are indispensable key equipment for port and offshore operations. As a leading company in this field, MAXTECH's marine stiff boom cranes demonstrate remarkable technical advantages in design, performance parameters, and special functions.
Design and Architecture
The rigid boom is the core feature of these marine cranes. MAXTECH has made meticulous efforts in boom design. The robust rigid boom can withstand enormous bending moments, giving the cranes a stronger heavy-load handling capacity. Moreover, it ensures high-precision load positioning. Whether it's the loading and unloading of containers in ports or the handling of precision equipment on offshore platforms, these cranes can perform tasks with ease.
Key Performance Parameters
Lifting Capacity
MAXTECH's marine stiff boom cranes cover a wide range of lifting capacities. Smaller models can handle loads as low as 5 tons, making them suitable for small fishing vessels or light-duty port operations. On the other hand, larger models can lift up to 100 tons. For example, the MAX 550 series cranes can effortlessly handle various types of cargo, including dry bulk, general goods, and containers, meeting the needs of maritime operations of all scales.
Outreach
The outreach of these stiff boom cranes typically ranges from 15 to 50 meters. A longer outreach offers significant advantages in port operations. For instance, in areas where containers are stacked in multiple rows, the crane can efficiently grab and place containers without the need for frequent repositioning, greatly improving operational efficiency.
Lifting Height
Some models can achieve a lifting height of over 35 meters. This parameter is crucial for scenarios such as loading and unloading cargo onto tall ships or for high-altitude operations on offshore oil rigs and wind farms, ensuring that heavy equipment can be smoothly hoisted to the designated positions.

Duty Cycle
Most of the products are designed with a duty cycle of A5, which falls under the medium-heavy-duty category. This design balances the durability of the cranes and cost-effectiveness, making them suitable for a variety of scenarios, such as daily cargo handling in ports and intermittent operations on offshore service vessels.
Special Functional Features
Corrosion Resistance
Given the harsh marine environment, MAXTECH attaches great importance to the corrosion resistance of its marine cranes. High-quality stainless steel materials are extensively used in key components, and long-lasting surface treatment technologies are applied. These measures effectively resist the erosion of seawater, salt spray, etc., significantly extending the service life of the equipment and reducing long-term maintenance costs.
Electro-Hydraulic Drive System
Equipped with an integrated electro-hydraulic drive/hydraulic power unit (HPU), this system enables smoother and more precise crane operation. Operators can easily adjust the lifting speed, luffing rate, and slewing speed, achieving fine-grained control of the load. Additionally, it features a high power-to-weight ratio, enhancing the operational efficiency of the cranes.
