Liebherr LTM 1230-5.1 Joins PT Pupuk Kalimantan Timur’s Fleet in Indonesia

30 Second Takeaway

Indonesia’s largest fertiliser producer, PT Pupuk Kalimantan Timur (PKT), has added a Liebherr LTM 1230-5.1 to its fleet its first Liebherr mobile crane.The 230-tonne, five-axle crane was selected for its single-engine efficiency, 75-metre telescopic boom, and ability to perform demanding lifts at high hook heights in confined plant environments.The crane will support critical lifting, maintenance and modernisation work at PKT’s major fertiliser production complex in Bontang, East Kalimantan.

First Liebherr mobile crane for PT Pupuk Kalimantan Timur

PT Pupuk Kalimantan Timur (PKT), one of Asia’s largest fertiliser manufacturers, has expanded its in-house lifting capability with the delivery of a Liebherr LTM 1230-5.1 All Terrain mobile crane.

The five-axle crane marks PKT’s first investment in Liebherr mobile crane technology, following an extensive evaluation process to identify a machine capable of meeting the company’s unique operational requirements.

“The LTM 1230-5.1 is perfect for our requirements.The 230-tonne crane from Liebherr is the only crane on the market that meets our specific needs,”said Joko Susilo, PT Pupuk Kalimantan Timur.

Designed for steep lifts and high hook heights

Operating within an active fertiliser production environment demands a crane capable of handling steep boom positions, high hook heights and restricted working areas.

The LTM 1230-5.1 delivers this capability through:

• A 75-metre, six-section telescopic boom

• VarioBase® Plus, providing real-time calculated lifting capacities for every outrigger position

• A compact footprint and reduced slewing radius, ideal for congested industrial sites

The crane’s LICCON control system continuously calculates available lifting capacity, maximising performance particularly in the rear working area.

Single-engine efficiency supports continuous production

A key factor in PKT’s decision was the crane’s single-engine concept, which reduces fuel consumption, operating costs and maintenance requirements.

“The single-engine concept ensures economical operation, and the 75-metre telescopic boom is indispensable for our daily lifting tasks,”Susilo explained.“The compact dimensions make it the ideal solution for our confined working areas.”

This efficiency is critical for a facility operating around the clock, where downtime and inefficiency directly impact production output.

Supporting one of Asia’s largest fertiliser complexes

The LTM 1230-5.1 will be primarily deployed at PKT’s Bontang production site, where the company employs approximately 1,300 people and operates:

• Five ammonia plants

• Five urea plants

• Three NPK plants

The crane will support:

• Lifting and installation of plant components

• Maintenance shutdowns

• Modernisation and upgrade projects

“With the LTM 1230-5.1, we can maintain and modernise our plants flexibly and safely,”said Susilo, adding that Liebherr’s service quality and reliability were also decisive factors.
