Cat® (Caterpillar) gas forklifts—primarily powered by LPG (liquefied petroleum gas)—offer a versatile, powerful, and increasingly clean solution for material handling. They bridge the gap between the zero-emission operation of electric trucks and the heavy-duty performance of diesel, making them ideal for both indoor and outdoor applications. This guide provides a comprehensive overview of Caterpillar's LPG forklift lineup for 2026, covering models, specifications, pricing, and key considerations.
Model Lineup – GP and GC Series
Cat LPG forklifts are organized into two primary series based on their tire type and application:
GP Series (Pneumatic Tires)
The GP series is the most versatile line, featuring flexible pneumatic tires designed for a wide range of indoor and outdoor surfaces, from smooth warehouse floors to uneven, weather-beaten yards. With nominal load capacities from 1.5 to 5.5 tonnes (and select models up to 7 tonnes), the GP series is suitable for diverse industrial applications. The new GP15-35(C)P range has been launched with updates to enhance operating economy and expand optional features.
GC Series (Cushion Tires)
The GC series is optimized for indoor environments with smooth concrete surfaces. Fitted with specific cushion wheels, these trucks offer a very high lifting capacity in tight spaces and are ideal for applications like mass storage of paper reels in warehouses without racking.
Key models span a wide capacity range, from the compact GC15K to the heavy-duty GC70K STR. For example, the GC40K STR features a robust V6 engine delivering 92.5 horsepower, while the GC70K STR boasts a maximum load capacity of 15,432 lbs (approx. 7 tonnes).
Technical Highlights – Power, Cleanliness, and Performance
Cat LPG forklifts are engineered with several key technologies that set them apart.
Advanced LPG Engines & Emissions Control
The trucks are equipped with electronic fuel-injected GCT GK21E or GK25E engines, offering high torque, reduced fuel consumption, and proven durability. A standout feature is the standard 3-way catalytic converter, which reduces harmful emissions by nearly 100%, enabling near-odourless operation indoors and meeting modern pollution standards.
Durability and Low Maintenance
To protect engines in dusty environments like construction sites or brickyards, the trucks feature a dual-element air filter and elevated air intake. The integrated Vehicle Control Module (VCM) facilitates easy troubleshooting and preventive maintenance.
Operator Comfort and Safety
The spacious operator compartment includes a fully suspended seat, adjustable steering column, and excellent panoramic visibility. The Presence Detection System (PDS) locks the truck if the operator leaves the seat, enhancing safety.
2026 Technology Upgrades
Recent updates include Bluetooth connectivity to a colour LCD display for wireless driver identification and access to the Cat TruckTool app. Additional features now include a standard speed limiter and an optional low LPG level warning.

Buying Considerations
1. Choose the Right Tire (GP vs. GC)
Select GP series for versatile indoor/outdoor use on varied surfaces. Choose GC series for dedicated indoor operations on smooth concrete floors.
2. Determine the Right Capacity
Match the forklift's nominal capacity to your heaviest typical load, plus a safety margin. The lineup ranges from 1.5 to 5.5 tonnes for LPG models.
3. Assess Your Environment
For dusty environments like construction sites, opt for models with the elevated air intake and dual-element air filter. For indoor use, the near-zero emissions from the 3-way catalytic converter are a significant advantage.
4. Factor in Operating Costs
While the upfront cost of an LPG forklift may be higher than an electric model, fuel is relatively inexpensive and refueling is quick. The 3-way catalytic converter ensures compliance with strict indoor air quality standards.
5. Test Before You Buy
If possible, test the specific model in your actual operating conditions. Many dealers offer rental options, allowing you to evaluate performance before committing to a purchase.
Summary
Caterpillar gas (LPG) forklifts offer a powerful, versatile, and clean solution for material handling. The GP series with pneumatic tires handles both indoor and outdoor surfaces, while the GC series with cushion tires excels on smooth indoor floors. Key advantages include advanced LPG engines with near-zero emission 3-way catalytic converters, robust durability, and operator-focused designs.
