Marine folding boom cranes combine high functionality with a compact design. Their robust steel structure and versatile hydraulic drive support all primary crane operations: hoisting, outreach adjustment, and slewing.
Compared to stiff boom models, these cranes require less space in the stowed position and provide a wider range of working areas during operation.
The 30T model equipped with a dual-hoist system provides high operational flexibility and efficient control. The 30 t main winch and 5 t auxiliary winch ensure reliable performance in sea states up to 2. The crane features a boom outreach of up to 43.2 m. The structural design provides effective protection of equipment from external influences and ensures convenient access for maintenance.

Marine Titan: Anatomy of a Crane Built for Ice and Storms
Imagine an icebreaker forging a path through Arctic floes. On its deck, amidst howling polar winds and clouds of ice spray, stands a multi-ton steel structure. This is no ordinary crane. It is a highly sophisticated mechanism engineered to operate with surgical precision in conditions ranging from tropical heat to fifty-degree frosts, all while enduring heavy sea states and intense hull vibration. This is precisely the machine Russian engineers developed for installation on the legendary icebreaker «Viktor Chernomyrdin».
At first glance, the task appears simple: lifting and moving cargo. However, a marine crane is a completely different story. Its purpose extends far beyond merely transferring a container from a pier to the deck. It is designed for offshore operations, where it can lower equipment to the seabed, assist in subsea pipe-laying, or even evacuate personnel from emergency sites using a specialized rescue man-basket.
The primary challenge faced by the designers was instability. A ship is never stationary: it rolls, lists, and experiences violent vibrations when breaking through ice. Despite these forces, the crane’s boom — carrying a 30-ton load at a height of 40 meters — must not swing like a pendulum. Controlling such a mechanism requires precision comparable to that of a surgeon.
To withstand extreme mechanical loads and arctic temperatures, the structure is fabricated from specialized high-tensile steel. This is not ordinary iron, but a high-strength alloy engineered to maintain its ductility and resist brittle fracture even at -50°C. The entire assembly — from the deck-integrated foundation to the specialized jib at the boom tip — is a massive, high-precision welded construction.
At the base of the crane lies a massive foundation. Mounted upon it via a large-scale Slewing System — essentially a giant bearing — is the crane housing. The housing provides continuous 360-degree rotation (endless slewing). Inside are the “heart and brain” of the machine: the control electronics, electric motors, and hydraulic systems. Externally, the heavy-duty main boom is attached to the housing, followed by an additional jib section. This “folding” design allows for an adjustable outreach ranging from 6.5 to 43 meters. To put this scale into perspective, it is equivalent to reaching the roof of a 15-story building from the ground.
How does such a titan move? The core power resides in the hydraulic system. High-pressure hydraulic fluid, maintained at optimal operating temperatures, flows through steel piping and high-pressure hoses. It drives the hydraulic cylinders which, acting like mechanical muscles, luff and fold the multi-ton boom and jib sections. The pump capacity required to circulate this fluid is a formidable 325 kilowatts, comparable to the output of a high-performance sports car.
But what if the vessel loses primary power? In an emergency, an auxiliary pump powered by an independent network takes over. Should that fail as well, the engineering provides a final failsafe. Each hydraulic cylinder is equipped with specialized load-holding valves. In standard operation, these are electronically controlled; however, in the event of a total power loss, they can be manually operated. This allows the operator to use gravity to safely lower the load or stow the boom, preventing a catastrophic failure.
Operating the crane involves far more than just a few levers. The operator is positioned in an ergonomic seat within a climate-controlled, insulated cabin featuring panoramic visibility. Integrated into the armrests are multi-axis joysticks sensitive to the slightest input. These allow for simultaneous motion: slewing the boom, hoisting the load, and adjusting the outreach all at once, with speeds ranging from millimeters per second to full velocity.
The “brain” of the crane is its sophisticated control system, which monitors dozens of parameters in real-time. Three inclinometers continuously measure the boom angle and the vessel’s trim and heel. Load cells integrated into the sheave blocks measure the actual weight on the hook. If the operator attempts to lift an excessive load, or if sea-induced dynamics cause the load to exceed the limit by 10%, the electronic overload protection system will automatically inhibit further movement. All critical data — current weight, safe working load (SWL), and inclination angles — is displayed on a touchscreen interface.
The crane can also be operated outside the cabin. For complex maneuvers requiring direct line-of-sight, a portable control station is used. Furthermore, for operations managed directly from the deck, a Radio Remote Control (RRC) system is available.
The marine crane is outfitted with an extensive array of safety interlocks. It will not engage if a maintenance hatch or access gate is open. Emergency cut-offs trigger if hydraulic oil levels drop below the threshold or if temperatures reach critical limits. Even if the operator fails to stop the hoist, the automatic system will cut off the winch three wraps before the hook reaches the block, preventing wire rope breakage. An anemometer continuously monitors wind speed; if it exceeds operational limits, the system halts movement to prevent the load from swinging.
This crane is a benchmark for durability. It is engineered for a 25-year service life and is capable of operating in any climate — from +35°C heat to extreme Arctic conditions where standard steel becomes brittle and hydraulic fluids thicken. It is designed to withstand a constant list of up to 15 degrees and rolling of up to 40 degrees. More than just a lifting machine, it is a sophisticated robotic complex and a testament to engineering excellence, ready for the ocean’s harshest challenges.
