The more it works, the more you save.

The 336E H uses three building block technologies to deliver outstanding fuel savings and performance for you:

  • The Cat Electronic Standardized Programmable (ESP) pump smoothly transitions between the hydraulic hybrid power sources, engine, and accumulator to conserve fuel.
  • The Cat Adaptive Control System (ACS) valve optimizes performance by intelligently managing restrictions and flows to control machine motion, which means your operators will have the power and precision they need and expect.
  • The Cat Hydraulic Hybrid Swing System captures the excavator’s upper structure swing brake energy in accumulators and then reuses the energy during swing acceleration.
Bottom line is the hydraulic hybrid system is a simple, reliable, and cost-effective solution that will help you significantly reduce your cost per ton.

Hydraulic Horsepower, a Cat Advantage

Hydraulic horsepower is the actual machine power available to do work through implements and work tools. It’s much more than just the engine power under the hood - it’s a core strength that differentiates Cat machines from other brands. In fact, pump and other system components put more power to the ground, which means moving more material in less time and keeping more money in your pocket at the end of the day.

Up to 25% less fuel consumption than 336E - the fuel economy and performance leader in its class. Up to 33% less fuel consumption than 336D.


Reduced emissions, economical and reliable performance you can count on.

The Cat C9.3 ACERT™ Tier 4 Interim engine is built to meet your demanding needs all day long. There is no interruption to your job process because the Cat regeneration system works automatically with no operator intervention required. If your operators are working in heat-restricted areas, they can use a manual override button to move the machine before the regeneration process begins.

Power Modes

The 336E H features three power modes to help manage fuel consumption: High power, standard power, and economy. Two additional fuel-saving features are on-demand engine power and engine idle shutdown. On-demand engine power keeps speed low during light loading and idling; it automatically adjusts speed up when it senses a heavier load. Engine idle shutdown automatically shuts the engine off when idling for more than a specified amount of time that you set, which can save significant amounts of fuel and reduce emissions.

Biodiesel-Ready Fuel System

The 336E H runs on ultra-low-sulfur diesel fuel, but you have added flexibility with the C9.3 ACERT engine because it’s equipped to run on biodiesel fuel up to B20. Just fill it up and go.

Operator Station

Your operators will enjoy the incredibly quiet and comfortable cab.


Your operators can adjust the right and left joysticks for individual preferences, making the machine much easier to operate and improving their productivity. They can also adjust the joystick control pattern electronically through the cab monitor instead of through a manual valve system. A heavy lift mode increases machine system pressure to improve lift - a nice benefit for your operators in certain situations. It also reduces engine speed and pump flow to improve controllability.


Your operators can focus on the job at hand with a high-resolution LCD monitor that is programmable in 42 languages to support today’s diverse workforce. It also projects the image from the rearview camera, further increasing job site safety and productivity.

Power Supply and Auxiliary Audio Port

The operator station includes two 12-volt power supply sockets located near the key storage areas for charging electronic devices such as MP3 players and cell phones. An auxiliary port allows operators to plug and play MP3 audio through the cab’s speakers.


Not only is the cab as quiet as today’s top pickup trucks, but several seat options help give your operators all the comfort they need for a long day of work. Air suspension and heated seats are available, and all include a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments.


Your operators can store their gear in storage spaces located in the front, rear, and side consoles. A dedicated space near the auxiliary power supply will hold an MP3 player and cell phone. The drink holder accommodates large mugs with handles, and a shelf behind the seat stores large lunch or toolboxes.

Automatic Climate Control

An automatic climate control system features five air outlets with filtered ventilation to make your operators comfortable in either hot or cold climates.

Structures & Undercarriage

You can take on a variety of tough tasks with this built-to-last machine.


You can expect excellent quality, reliability, and durability with the 336E H’s reinforced lower and upper frames. Both are built to handle a hard day’s work over and over again.


Long undercarriage supports any type of work required from a 36-ton machine. Heavy-duty track rollers, precision forged carrier rollers, press-fit pin master joints, and enhanced track shoe bolts enhance machine durability and reduce the risk of downtime and your need to replace components. A three-piece guiding guard helps maintain track alignment and will improve your machine’s overall performance.


Whether you are truck loading or trenching, a 4.9 mt (5.4 t)* counterweight gives you plenty of weight and balance for the high-production work this machine is designed to take on. With integrated links, the counterweight can easily be removed for maintenance or shipping. *Two accumulators and a bracket provide additional weight.

Work Tools

You can dig, hammer, rip, and cut with confidence.

Couplers: Quick Tool Changes

Imagine the productivity you’ll achieve with a quick coupler. Combine a robust coupler with a common work tool inventory that can be shared between same size machines and you’ll get performance and flexibility on every job. The Cat Center-Lock™ pin grabber coupler features a patented locking system and highly visible lock. You can clearly see when the coupler is engaged or disengaged from the attachment.

Work Tools: Cut, Crush, Pulverize and Load

No matter your specialty, Caterpillar provides tools that are perfectly matched to get the most out of your Cat machine - quickly and efficiently. Auxiliary hydraulic circuits are available to integrate any Cat work tool with your 336E H.

Buckets: Dig, Move, Load

Cat buckets are designed to fill efficiently so you notice a fast, smooth cycle, which means high productivity each time you dig. Wear characteristics of general-duty, heavy-duty, and severe-duty buckets give you solid performance in a wide variety of material abrasions. Ditch cleaning and other specialty buckets are available when needed.

Front Linkage

You’ll experience a long service life even in the harshest of conditions.

Your uptime and service intervals are increased with high-quality, durable, and reliable booms, sticks, and linkage pins. Each boom and stick is built with internal baffle plates for additional durability, and each undergoes ultrasound inspection to ensure quality and reliability for the tough work you do. There is one heavy-duty reach boom and two heavy-duty stick options: a 6.5 m (21'4") boom and a 3.2 m (10'6") and 3.9 m (12'10") stick. The heavy-duty reach boom covers all the applications this size of machine was designed to take on such as digging dirt, moving rock, placing pipe, and the endless amount of tasks that can be done with Cat hydraulic work tools. The longer 3.9 m (12'10") stick is best for deep trenching and truck loading or simply when more reach is needed in an application; the shorter 3.2 m (10'6") stick is best for shallow digging where more breakout force is needed or if you plan on primarily using hydro-mechanical work tools to complete your job.

Integrated Technologies

Make your team’s work easier and more efficient.

Cat Product Link™

You can monitor and improve your fleet management with Cat Product Link. The integrated system reports events, diagnostic codes, hours, fuel consumption, location, and other pieces of detailed machine information to the secured web-based application called Vision Link™. The powerful tools within Vision Link communicate with you and your authorized Cat dealer to help avoid downtime and better maintain your fleet.


You can depend on safe, fast, and easy access.

Ground-Level Compartments

Your service technicians have ground-level access to the radiator, pump, and air cleaner compartments through wide service doors, making it easy for them to reach, check, and replace fluids and filters.

Other Service Benefits

The water separator with water level sensor has a primary fuel filter element located in the pump compartment near ground level; the electric priming pump is mounted on the primary filter base and is easier to service than traditional hand-priming pumps. The engine oil dipstick is conveniently located in the front of the engine compartment. The fuel tank’s remote drain cock makes it easy and simple to remove water and sediment during routine maintenance. Overfilling the fuel tank is significantly reduced with an integrated fuel level indicator.


Several built-in features will help protect your people.

Roll-Over Protective Structure (ROPS) Cab

Your operators will benefit from the enhanced protection of a ROPS-certified cab.

Sound Proofing

Roof lining and sealing make your operator’s sound experience inside the cab comparable to any of today’s top pickup trucks. In fact, you won’t believe it’s running.

Anti-Skid Plates

Your operator and service technicians’ slipping hazards are reduced with anti-skid plates on the surface of the upper structure and the top of the storage box area.

Steps, Hand and Guard Rails

Service technicians can work securely on the machine with extended hand and guard rails to the upper deck and steps on the track frame and storage box.


Halogen lights provide plenty of illumination. They can be programmed to stay on for up to 90 seconds after the engine has been turned off to help your operators safely exit the machine.


You can easily store both the upper and lower windows in the cab. Overhead visibility and lighting are enhanced with a large skylight that can double as an emergency exit.
