Servoday manufactures and supplies different types of grabs according to the crane, material characteristics, lifting capacity, working environment and operating requirements.
The company’s published grab range includes:
The grab design can be adapted according to the bulk density, particle size, abrasiveness, moisture, required volume, crane parameters and application conditions.
Different cargoes require different grab designs. Servoday’s published port-handling applications include a wide range of dry bulk and irregular materials.
Coal is one of the major bulk commodities handled at ports. Clamshell and radio remote grabs can be used for ship unloading, barge loading and stockyard transfer.
Heavy-duty grabs can be designed for materials such as:
Material density and abrasion characteristics are important considerations when selecting the grab configuration.
Fertilizer materials such as bulk granular products can require controlled and efficient loading/unloading systems.
Depending on the cargo characteristics, grabs can be used for handling bulk agricultural commodities such as grains and similar free-flowing materials.
Bulk salt handling is another port application where radio remote grabs and other suitable grab configurations can support loading and unloading operations.
Clamshell grabs are widely suited to loose bulk materials such as:
Orange Peel Grabs are particularly suited to irregular and bulky materials such as steel scrap, where multiple curved tines can grip individual pieces and bundles.
Specialized Timber/Log Grabs are designed for handling cylindrical and elongated wood materials, including logs and biomass-related materials.
Rock grabs and heavy-duty attachments can be configured for rocks, rubble and other difficult materials.
Depending on the application, suitable grabs can be used for:
Servoday’s published port-handling information also lists municipal waste and other irregular materials among potential applications.
A typical bulk-material movement can involve:
Ship / Barge → Crane → Grab → Port Hopper → Conveyor → Stockyard → Processing / Dispatch
or the reverse:
Stockyard → Conveyor / Hopper → Crane → Grab → Ship / Barge
Servoday also manufactures or supplies associated bulk-handling equipment such as port hoppers, conveyors, material-handling equipment and ship/barge loading systems, allowing grab equipment to become part of a broader material-handling system.
A grab should not be selected only by volume. Important engineering parameters include:
1. Material Density
Determines the payload that can be carried by a particular grab volume.
2. Material Characteristics
Coal, ore, scrap, logs and grains behave differently and require different designs.
3. Crane Capacity
The crane’s safe working load must accommodate the grab dead weight plus the material payload.
4. Grab Capacity
Grab volume should be matched with material density and required productivity.
5. Working Depth
Ship holds, barges and deep stockpiles may require different grab configurations.
6. Abrasion Resistance
Highly abrasive materials can require suitable wear-resistant components.
7. Operating Cycle
Fast filling, lifting, travelling and discharge cycles can influence overall port productivity.
8. Environmental Conditions
Marine environments can expose equipment to salt, moisture, corrosion and demanding operating conditions.
Servoday’s engineering activities extend beyond the grab itself. The company describes capabilities covering design, fabrication, manufacturing, installation, assembly and commissioning of industrial and bulk-handling systems.
This allows a project to be approached from the engineering level:
Application Study → Grab Selection → Mechanical Design → Fabrication → Assembly → Testing → Site Installation → Commissioning
For customized grab requirements, parameters such as crane make/model, SWL, rope arrangement, material density, required capacity, operating depth and material characteristics become important inputs.
| Grab / Equipment | Typical Material / Application |
|---|---|
| Radio Remote Control Grab | Coal, salt, fertilizer, grains, minerals |
| Two-Rope Mechanical Grab | Bulk cargo, sand, coal, aggregates |
| Four-Rope Clamshell Grab | Heavy bulk cargo and deep handling |
| Electro-Hydraulic Clamshell | Bulk material handling |
| Orange Peel Grab | Steel scrap and irregular materials |
| Timber / Log Grab | Logs, timber, wood materials |
| Rock Grab | Rocks, rubble, heavy aggregates |
| Clamshell Attachment | Excavator/material-handler applications |
| Port Handling Hopper | Receiving and transferring bulk materials |
The exact configuration and capacity should be engineered according to the crane, material and operating conditions.
