What the specifications mean
The published GRT780 values remain attached to their stated configuration and rating basis.
Standard 23.5 x 25 tires, five-section boom retracted and lowered, auxiliary boom nose as drawn; outriggers retracted.
An individual machine must be verified by serial/PIN, installed equipment and actual measurements.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used GRT780 inspection priorities
- Use a qualified crane inspector and reconcile the serial-specific machine with its current documentation.
- Inspect boom structure, wire rope, sheaves, cylinders, carrier, outriggers and safety systems.
- Match ballast, hook block, jib and outrigger state to the exact manufacturer load chart.
- Match the GRT780 model plate, fitted equipment and serial/PIN to the cited generation and configuration.
Configuration-aware inspection: these checks are triggered by machine category, installed configuration and technology package. Brochure-listed technology must be physically present, active, licensed and calibrated on the used machine.
Hours, condition and ownership cost
Hours are context, not a condition grade. Duty cycle, idle time, maintenance evidence, wear-system measurements, structural repairs and installed technology should be evaluated together.
Cost drivers to model
- Structural inspection, certification, wire rope, tires and carrier maintenance require crane-specific reserves.
- Boom, jib, ballast and hook-block packages affect both value and mobilization.
- Transport and setup costs must include every separately carried component.
Compatibility graph
Attachment considerations
Relationships below identify relevant classes only unless a stronger evidence state is shown. They never assert exact used-attachment fitment.
Hook blocks, jibs and lifting accessories
Verify serial-specific chart, reeving, component weight, manufacturer approval.
Open attachment researchBefore confirming fitment
- generation and machine configuration
- mounting interface, coupler or pin geometry
- hydraulic flow, pressure, return and case drain
- attachment weight and machine capacity limits
- electrical controls or required machine options
Model-reference transport profile

Reference measurements retain their configuration and verification status. Confirm the actual transport setup before booking.
Measurement basis: Grove GRT780 — Standard 23.5 x 25 tires, five-section boom retracted and lowered, auxiliary boom nose as drawn; outriggers retracted.
Reference specifications can differ from the actual configured machine. Confirm dimensions and weight before booking transportation.
Confirm or replace before a transport request
- actual weight
- actual travel length, width and height
- attachments and removable work tools
- bucket, blade, carriage or boom position
- loading condition
