REMOTE OPENING / CRANE RETROFIT
Remote-Controlled Hydraulic Clamshell Grab
A remote-opening hydraulic clamshell can help an existing crane handle bulk cargo without adding a conventional closing-rope system. The remote signal, hydraulic energy source and recharge method depend on the chosen design. Confirm how the bucket closes, opens and behaves if power or communication is lost before ordering for port, yard or ship-hold work.

- ORDER BASIS
- Project configuration
Send your crane make and rated load, hook drawing, available headroom, cargo density, opening location, daily cycles and the site's charging or power options.
01
One-unit enquiries welcome
The selected attachment's minimum order and supply scope are confirmed in the written offer.
02
Crane and attachment checked together
Review the loaded attachment, connection, operating cycle and site clearances before approval.
03
Clear delivery and support scope
Agree inspection, documents, packing, schedule, site support and warranty before order placement.
01 / SPECIFICATIONS
Specify the operating sequence before a nominal bucket size.
A remote grab's capacity and self-weight depend on its chosen shell and hydraulic package. The selected-unit offer should state every value below together on one drawing and technical schedule.
Swipe to compare the complete selected-unit parameters →
| Parameter | State in the RFQ | Confirm on selected unit |
|---|---|---|
| Bulk material | Name, density, size and moisture | Maximum filled material mass |
| Grab size | Desired tonnes per cycle | Volume, open width and self-weight |
| Crane interface | Hook drawing, rating and headroom | Loaded mass and connection dimensions |
| Hydraulic energy | Available charging or cable route | Chosen power package and cycle endurance |
| Remote function | Required opening point and operator view | Range, fail-safe response and manual recovery |
| Site exposure | Dust, rain, salt air and temperature | Protection and maintenance schedule |
No single published capacity or battery figure applies to every remote grab. Do not approve the crane by bucket volume alone: add the selected grab self-weight to its maximum cargo mass.
Can my present hook crane use a remote grab?
It may, but confirm the actual total loaded mass, hook connection, headroom, lift path and the remote opening procedure. Ask for a drawing and operating demonstration for the selected grab before assuming the retrofit works.
Review the configuration
02 / APPLICATIONS
Where a full closing-rope retrofit is impractical.
01
Ship holds and quay hoppers
Position the opening action over the discharge area while checking operator sight lines, grab width and clearance at the hatch and hopper.
02
Existing gantry or mobile cranes
Use an existing hook where the crane rating, geometry and operating cycle are compatible with the new attachment and its energy package.
03
Bulk-yard transfer
Size the shells for cargo density and target throughput; check environmental protection and service access for repeated outdoor cycles.
A photograph of a remote grab does not establish its exact model, volume or lifting rating. Confirm those for the unit quoted against your crane and cargo. Compare the matching crane system.
03 / CONFIGURATION
Choose the attachment around the actual lift.
Select the bucket and hydraulic package around the existing crane's hook, available headroom and handling cycle. Define how the unit is charged, opened, inspected and recovered before confirming the retrofit and discharge sequence.
04 / QUOTATION SCOPE
Compare a complete attachment package.
Equipment price, crane modifications and site services should be separated so your team knows what is supplied and what remains to be done locally.
Complete grab package
Identify shells, hydraulic unit, energy storage or supply, remote transmitter/receiver, lifting head and actual self-weight.
Crane integration
State hook connection, optional charging or cable equipment, control interface and operator responsibility.
Demonstration and handover
Agree the opening test, safe recovery procedure, inspection documents, export packing and service spares.
05 / ORDERING & DELIVERY
Approve the selected unit before manufacture.
The offer should connect your load data to one drawing, one equipment schedule and a clear inspection and handover plan. Production and freight dates are confirmed for that selected configuration.

POWERED CLOSING / BULK MATERIAL
Electric Motor Clamshell Grab Bucket

A single lifting rope simplifies the crane connection, but the bucket's opening sequence becomes the key selection question.
View product ↗07 / BUYER QUESTIONS
Questions to settle before buying.
Use these answers to prepare one technical and commercial brief for the selected unit.
Discuss this attachmentDoes remote control mean the bucket has no power requirement?
No. The remote command and hydraulic closing action need a defined energy source or charging arrangement. Confirm the package for the selected model.
Will it fit any 10 t crane?
No. Crane rating is only one check. The loaded grab weight, hook dimensions, headroom, clearances and duty must match the actual crane.
Can it open above a ship hopper?
That must be verified for the selected opening mechanism and control sequence. Provide hopper dimensions and the required discharge height.
What happens if the remote signal fails?
The technical offer should state the selected unit's safe response, status indication and recovery procedure for the intended duty.
How are lead time and support handled?
The written offer confirms the selected power package, test scope, production and shipping milestones, warranty and spares.
