Izhora Hydrosystems LLC presents a special-purpose marine overhead crane with a lifting capacity of 3 t, designed for lifting, lowering, and longitudinal and transverse handling of cargo within a ship’s hold. The crane is intended for handling cylindrical loads with diameters ranging from 123 to 533 mm and lengths of up to 8 m. During cargo handling operations, the crane ensures:
The marine overhead crane was developed for installation on a naval training torpedo recovery boat of the Russian Navy and is intended for recovery of practice (inert) torpedoes from the water after training exercises. The crane design incorporates non-standard engineering solutions aimed at reducing overall mass and dimensional characteristics.
The lead project of the special-purpose marine overhead crane, developed under contract for the Navy, complies with the following regulatory documents:
Izhora Hydrosystems LLC is ready to adapt the marine overhead crane design for naval and civilian applications, taking into account the structural and operational characteristics of the customer’s vessel.
The crane can be customized for handling cargo with any specified parameters in ship holds of various types, as well as for operation at stationary onshore facilities.
The special-purpose marine overhead crane manufactured by Izhora Hydrosystems LLC offers the following advantages:
Depending on the purpose, class, and operating area of the vessel, Izhora Hydrosystems LLC adapts the special-purpose overhead crane design to comply with the requirements of the Russian Maritime Register of Shipping, the Russian River Register, the Ministry of Defence of the Russian Federation, and other relevant regulatory and supervisory authorities.
In the standard configuration, the crane is equipped with a twin-drum winch, with wire rope tension maintained by a spring-loaded tensioning unit. For improved rope reeving and more accurate load positioning, the crane may be equipped with two independently driven winches, each operating with a separate wire rope on its own drum. This configuration eliminates the need for symmetrical winding of identical wire ropes and allows independent tension adjustment.

Izhora Hydrosystems LLC was approached by a shipyard that was unable to identify a Russian manufacturer capable of delivering the full project cycle for a special-purpose marine overhead crane, including engineering design, approval by supervisory authorities, manufacturing, and commissioning. The task was further complicated by severe dimensional constraints, particularly strict limitations on the overall crane height, which fully excluded the use of standard serial overhead cranes produced by conventional crane manufacturers.
In response, Izhora Hydrosystems LLC designed and manufactured a custom special-purpose marine overhead crane, implementing a non-standard technical solution that enabled installation of the equipment inside the hold of a torpedo recovery boat. In this design, the bridge and trolley are driven by tensioned wire ropes from a twin-drum winch, with no moving drive units installed on the bridge or trolley. As a result:
The crane was designed and manufactured in full compliance with the customer’s technical and operational requirements.
The marine overhead crane is designed for reliable operation at ambient temperatures from –32 °C to +30 °C and under sea conditions up to Sea State 3. The crane bridge has two primary positions: working and stowed.
When the vessel is underway and the crane is in the stowed position, the following conditions apply:
In the working position, winches are used to move the crane bridge and load trolley along the ship’s hold, while the load trolley hydraulic cylinder performs lifting and lowering of the load.
Crane operation includes the following procedures:
In abnormal or emergency situations, crane operation is stopped and blocked by pressing any EMERGENCY STOP push button located on the control pendant or hydraulic power units.
Upon completion of cargo handling operations, a visual inspection of the equipment is carried out to verify the absence of mechanical damage and confirm proper technical condition.
The crane is then returned to the stowed position, the hydraulic power units are shut down, and the power supply is disconnected.
General Arrangements and Design
The crane bridge is a welded steel structure that moves on support rollers along crane rails welded inside the hold to the vessel’s side and deck structural members. The rails are manufactured from No. 20 steel channel sections, reinforced on the underside with plate-steel stiffening ribs. The welded load trolley, equipped with its own travel drive and dedicated hydraulic power unit, travels along the bridge on support rollers.
The load hoisting and lowering mechanism, installed on the load trolley, is a two-stage telescopic system with a single centrally mounted hydraulic cylinder.
To allow load engagement at an angle, a hinged fork with a lifting yoke compliant with OST V5.2423-83 is mounted at the end of the hydraulic cylinder rod.
To reduce load sway, the crane is equipped with a spreader beam incorporating pivoting guide rods fitted with calibrated guide rollers and limiting clamps. Additional removable gauge limiters may be installed on the pivoting rods to facilitate handling and positioning of loads shorter than 3 meters.
Operating principle: during hoisting or lowering, the rollers roll along the surface of the load without restricting vertical movement, while the limiting clamps prevent rotation of the load about the hydraulic cylinder rod axis. When the load reaches the uppermost position, the pivoting guide rods are locked by the load fork via a roller stop. This prevents load sway during subsequent transverse and longitudinal movement within the hold for placement in the designated stowage location.
Two independent wire-rope winches, powered by two separate hydraulic power units (HPUs), are used for traveling the crane bridge and the load trolley. Travel is limited by end-position sensors and fixed mechanical end stops. Each winch comprises a grooved drum for wire rope spooling, a gearbox, a brake, and a hydraulic motor.
Fixation of the crane bridge in the stowed position is provided by brackets welded to the crane runways and fitted with hydraulic cylinders. The cylinders extend locking rods into travel limit stops welded to the crane bridge, ensuring secure locking during vessel transit.
The steel control cabinet houses the electrical control equipment, hydraulic power unit control devices, and operating status indicators for both the hydraulic power units and the crane. The cabinet is equipped with interfaces for main power supply connection and for connecting the portable control pendant cable.
The cable-connected portable control pendant is a handheld unit equipped with crane control and status indication devices. For operator convenience, it is fitted with a shoulder strap. In the stowed position, the wearable control pendant remains connected to the load trolley and is stored on the protective cover of the hoisting hydraulic cylinder.
The marine overhead crane and all equipment included in its configuration comply with generally accepted standards in force at the time of design and manufacture and are recognized as safe for operation.
The equipment shall be used only under the specified and safe operating conditions. During operation, due caution shall be exercised, with continuous visual monitoring of crane operation, the position of moving parts, and the reeving and spooling of wire ropes.
To ensure safe operation of the crane, the following requirements shall be observed:
During functional testing of the marine overhead crane, only personnel directly involved in servicing the equipment are permitted to be present within the working area. All testing shall be carried out under the supervision of a designated responsible person.
The electrical equipment and control system of the marine overhead crane provide the following primary interlocks and protective functions during operation:
To ensure operational reliability and fault tolerance, the marine overhead crane is equipped with:
In emergency operation mode, hydraulic pressure required for crane operation is generated by manual pumps installed on both the trolley and bridge hydraulic power units. The pumps are positioned to allow convenient and safe operation at any location along the crane travel path within the cargo hold.
To maintain the marine overhead crane in proper technical condition, ensure continuous operational readiness, and guarantee correct and safe operation, the requirements of the Operation and Maintenance Manual developed by Izhora Hydrosystems LLC shall be strictly observed. Failure by operating personnel to comply with the rules and requirements of the Operation and Maintenance Manual shall invalidate the right to submit warranty claims.
The obligations and warranty responsibilities of the manufacturer, Izhora Hydrosystems LLC, are defined in the equipment supply contract. The scope of warranty obligations stipulated in the contract shall not be expanded or restricted based on information contained in the Operation and Maintenance Manual for a specific unit.
The standard scope of supply includes:
The scope of supply for optional equipment may differ from the configurations and illustrations presented on the website, as the equipment is manufactured in various versions, configured according to customer requirements, or modified in line with ongoing engineering development.
The crane is supplied in disassembled and packaged condition by any mode of transport that ensures compliance with Storage Condition “8” in accordance with GOST 15150-69. Prior to transportation, crane assemblies are preserved and packaged by the manufacturer, with the exception of oversized structural elements.
