Truck crane repair and maintenance

Repair and maintenance of Liebherr, Grove truck cranes

Liebherr LTM, Grove GMK, and XCMG QY - are three different design platforms with their own hydraulics, electronics, and specific components.

Repairing a Liebherr LTM requires knowledge of the LICCON control system and the architecture of the hydraulic lifting and telescoping circuits.Grove features the American Manitowoc component base with its own diagnostic protocols.

XCMG runs on Rexroth hydraulics and Cummins engines - a reliable component base, but with the specifics of Chinese assembly, which not every service knows from the inside.

ILIEV Solutions coordinates the repair of each of these platforms and provides the supply of OEM spare parts by the serial number of a specific machine.

Diagnostics of hydraulics, booms, and crane mechanisms

Truck crane diagnostics begins with the components that bear the maximum load in the working cycle.
‍

Hydraulic system: pressure in the lifting, boom telescoping, and outrigger extension circuits, condition of pumps, distributors, and high-pressure hoses.
Telescopic boom: sections, slide guides, rollers, and hinges. Winches: brake discs, clutches, load-bearing rope, and limit switches.
Control system: reading error codes of the load moment indicator unit, calibrating angle and boom reach sensors.

Based on the diagnostic results, the client receives a defect list with a specific list of works and spare parts, without vague phrases like "requires attention".

Scheduled maintenance of truck cranes: regulations and timing

Scheduled maintenance according to the manufacturer's timetable - is the most effective way to keep the crane in working condition and avoid emergency stops in the middle of the installation season.

For Liebherr and Grove, the first level of maintenance is scheduled every 500 engine hours: changing the engine oil and filters, checking the hydraulic fluid, lubricating the boom hinges and outriggers.

Every 2,000 engine hours, comprehensive maintenance is performed, including checking the braking system, the condition of the load-bearing winch rope, and calibrating the control system.

ILIEV Solutions creates a schedule for a specific machine, provides the necessary consumables, and coordinates the execution of maintenance in the window between projects so that the crane does not stop the contractor's work.

Emergency repair of cranes at the construction site

During an emergency crane stop, there is only one priority - to return the machine to work as quickly as possible.ILIEV Solutions organizes prompt diagnostics: remotely clarifies the symptoms of the malfunction, identifies the component, and makes a decision on the intervention format: a visit to the site or transportation to the service base.

Simultaneously, the availability of necessary spare parts in regional warehouses is checked. The goal: minimal time from the request to the restoration of the crane's operation, rather than a lengthy approval process through multiple intermediaries.

How to order a truck crane repair through ILIEV

To start, you need to provide three things: crane model, serial number, and a description of the technical malfunctions.

Then ILIEV Solutions manages the entire process:

Remote consultation: an engineer analyzes the description, clarifies error codes, and forms a preliminary picture of the malfunction

Determining the format: visit to the site or transportation of the crane to the service base

Diagnostics and defectation: a specific defect list with a list of spare parts and the scope of work

Approval and supply of OEM components: by machine serial number, deadlines are confirmed before the repair begins

Repair and handover: transfer of the crane with control parameters of hydraulics, electronics, and mechanical components

Field diagnostics and repair at the client's site

■

If the crane cannot leave the site, ILIEV Solutions travels to the location.

■

The field format covers hydraulic diagnostics, replacement of seals and high-pressure hoses, setup and calibration of the control system, and minor repairs of mechanical components without stopping the rest of the work on the site.

■

More complex interventions: replacing the hydraulic pump, repairing the winch reducer or boom sections - are performed at the service base.Field service is available in Ukraine.

Frequently Asked Questions

Where to repair a Liebherr truck crane in Ukraine?

ILIEV Solutions organizes diagnostics and repair of the Liebherr LTM series in Ukraine - field service at the site or at the service base.

OEM spare parts by machine serial number through direct contact with Liebherr. To start: crane model, serial number, and description of the malfunction.

What is included in the scheduled maintenance of a truck crane?

The first level of maintenance every 500 engine hours: engine oil and filter replacement, hydraulic fluid check, lubrication of boom hinges and outriggers.

Every 2,000 engine hours, a comprehensive check of the braking system, load-bearing winch rope, and control system calibration. The schedule is compiled for a specific crane model.

Is field repair of a truck crane possible at the site?

Yes. ILIEV Solutions performs field diagnostics and repair at sites in Ukraine. The field format is suitable for hydraulic malfunctions, seal replacements, and electronics setup.

Complex repair: boom sections, winch reducer requires a service base.

Which truck crane components require unscheduled repairs?

The most frequent unscheduled failures: hydraulic pumps and high-pressure hoses, outrigger and telescoping cylinder seals, winch brake discs, load moment indicator system sensors.

On cranes without regular maintenance, hydraulic pumps and boom seals are the first to fail.
