GE Series / Electric-Driven Grab Dredging Crane

Grab Dredging

Grab Dredging Work of Low Noise
The Function as It Is but Providing Energy Saving and Powerful Dredging Work

The GE series of electric-driven grab dredging crane are the marine crane that exercises full power to dig sediment at the sea bottom in dredging construction.

As the engine is not equipped, the noise around the crane is greatly reduced, and the operator’s operating environment is greatly improved.

Clean machine room without oil leakage, easy maintenance and the running costs is significantly lowered down. In addition, as it is controlled by electrical signals it is highly scalable, and IoT can be expected.

In port and civil engineering work, the sediment on the sea bottom is grabbed by the dredging crane to create a port.

We are proud of the strength and safety of the crane that can withstand the harsh environment of the sea and they are active not only in Japan but also overseas.

All designs and manufactures are made to order, and we design one by one according to the customer’s request and the content of the construction work.

Main Uses Mainly used for dredging service for route and berth, also able to be customized to multi-purpose types of rock-breaking or/and load lifting service
Example of Customization By attaching with hook, load lifting service available.

Features

People and the Environment Friendly Crane

People and the Environment Friendly Crane

As it is driven by electricity and not equipped with an engine, it is very quiet during work, it is the crane kind to the site environment and the operator.

Set to An Easy-to-Use Operating Environment for Operators

Set to An Easy-to-Use Operating Environment for Operators

Elements for control such as speed control and various operation of crane movement can be adjusted by operator to an easy-to-use setting.

Vibration and Noise Countermeasures to Reduce Operator Fatigue and Burden

Vibration and Noise Countermeasures to Reduce Operator Fatigue and Burden

An independent anti-vibration system for operator’s cab is adopted by putting anti-vibration rubber between the machine body and the operator’s seat, in this way to minimize the vibration of the machine body transmitting to the operator’s seat. Compared to conventional cranes, operator’s fatigue and burden is much more lightened. Additionally, by providing enough soundproofing, operator can have a conversation without stress even while working in the crane.

Surveillance Cameras, Sensors and Alarm Devices to Ensure Safety

Surveillance Cameras, Sensors and Alarm Devices to Ensure Safety

Surveillance cameras are equipped over the drums so as to help operator watch the winding status of the wire rope. In addition, various devices are installed to ensure safety, such as the alarm that reacts to each over-hoisted and overload, and the stop slewing function by the sensor installed on the foldable stairs for boarding crane.

Simple Operation to Open and Close the Grab Bucket Smoothly

Simple Operation to Open and Close the Grab Bucket Smoothly

By putting the hoisting and open-closing operation levers in the clutch position, only with one control lever it is carried out to wind up and lower down the grab bucket easily. Moreover, the grab bucket opening degrees meter helps operator understand grab bucket opening degrees within from 0% to 100% in real time.

Set to an Easy-to-Use Operating Environment for Operators

Set to an Easy-to-Use Operating Environment for Operators

Various control such as torque converter in speed control mode or torque control mode, and various operation of crane movement can be adjusted to the operator’s easy-to-use settings.

Inverter (Vector Inverter)

Inverter (Vector Inverter)

Excellent control ability, stable speed control from the low rotation range is possible. It enables quick start-up, and the efficiency of the work is achieved by extremely smooth speed control and stop.

Touch Panel

Touch Panel

The touch panel is equipped in the operator’s cab which enables various settings to meet with working conditions, such as the winding of the grab bucket and the slewing angle of the crane. In addition, in the event of an abnormality, the abnormal part is indicated as well.

Main Options

GPS Grab Dredging Engineering Management System

GPS Grab Dredging Engineering Management System

On the monitor of this system the dredging spot and depth can be checked in real time. By setting working spot in advance, the progress of dredging work is confirmed through the monitor which enables operations accurate without waste. Moreover, the work done is recorded, which is useful for making retrospections and reports

Flat-Dredging Control System, Depth Meter/Grab Bucket Open-Closing Degree Meter

Flat-Dredging Control System, Depth Meter/Grab Bucket Open-Closing Degree Meter

The flat-dredging control system, developed by SKK in 1989, is a control system that by control the sinking degree of grab bucket so as to make the dredged trace on sea bottom near flat surface less of roughness. The sinking degree is automatically detected and controlled by the system and succeeded in significantly reducing dredging sediment residue. Quick and high-precision dredging work is now possible. The depth meter is an instrument that enables automatic deceleration and stop of grab bucket at a specified depth. There is not any more wire rope is reeled out after grab getting to the bottom so that the working time is shortened. In addition, the grab bucket opening degrees meter helps operator understand grab bucket opening degrees within from 0% to 100%.

Hook Pocket

Hook Pocket

Hook pocket is used to store and fasten an unused hook. This makes it possible to do grab dredging work without removing the hook. It leads to shorten the working time.
