Kalmar TT618i/TR618i/TRL618i: unparalleled performance, durability, and versatility for heavy load handling

Kalmar has made its pioneering i-model terminal tractors even better with improvements to lifetime durability and operator comfort. The result is robust reliability and excellent performance when moving heavy loads in any type of condition.

The Kalmar TT618i (4x2) and TR618i (4x4) handle semi-trailers and terminal trailers for containers and roll trailers with goosenecks. For mega and jumbo trailers, the low-chassis TRL618i (4x4) has been specifically designed to handle mega and jumbo trailers.

Our range of heavy terminal tractors can be used for RoRo handling, container handling in harsh winter conditions, container trailer train (MTS), general cargo handling with gooseneck and roll trailer, and industrial handling with special trailers.

Designed for better performance

Based on extensive studies carried out in cooperation with drivers and specialists in ergonomics, the Kalmar 618i Terminal Tractors feature improved visibility and performance, a machine that is easier to maintain and an enhanced operating environment for your drivers.

For RoRo handling, all Kalmar heavy-duty 618i Terminal Tractors have better traction so they can easily climb steep ramps and perform tight turns on slippery decks. 

All Kalmar terminal tractors are still the only tractors on the market with the advanced CAN-Bus system, which integrates all operating functions in one system and shows all operational and service data on one display.

Frequently Asked Questions

What is different about the three different Heavy Terminal Tractors models available?

We have three models available. There is the Kalmar 2-wheel drive terminal tractor for RoRo handling and two different 4-wheel drive models to make moving heavy loads quicker and safer. Making them ideal for RoRo, Ports or Terminals and Industrial applications.

What is the lifting capacity of Kalmar's Heavy Terminal Tractors?

There are three different Heavy Terminal tractor models available each with different lifting capacities, our TT618i and TRL618i have 5th wheel standard lifting capacities of 25,000kg, with double lifting cylinders optional available on both machines, raising the lifting capacity to 32,000kg. Our TR618i Heavy Terminal Tractor comes with a 32,000 kg lifting capacity as standard.

What is the difference between a RoRo and LoLo Terminal Tractor?

RoRo is short for Roll on Roll Off and is used to name Terminal Tractors that are designed to work on slippery surfaces and have to access or deliver loads via a ramp into ferries or other forms of transport. LoLo terminal tractors have been designed to be able to handle very heavy loads often loaded on mega or jumbo trailers.

What is the difference between the Kalmar Heavy and Eco Heavy Terminal Tractors?

Both are heavy terminal tractors and both offer RoRo and LoLo versions, the difference being the fuel efficiency of the different ranges. The Eco Heavy Terminal Tractor has an optimised driveline combination using the latest technology, enabling it to use 30% less fuel and produce 30% less carbon emisions than our standard range of Heavy Terminal Tractors.
