The 45 Series, Thomas’ 4.5 ton model features reliable Isuzu diesel power. The liquid cooled, 4 cylinder engine puts out a hard working 44.8 horsepower (33 kw).

With Thomas you get more reach, dump height and more digging depth. The 45 comes standard with a long dipper arm which provides you a full 13 ft. 4.8 inch (4085mm) digging depth. That’s more than a foot (305 mm) deeper than most other excavators in its class.

You don’t have to sacrifice breakout force in order to dig deep. The 45 boasts a mighty 9941 lbs. (4509 kg.) of bucket breakout force, enough to muscle its way through the toughest digging conditions.

For your convenience or for multiple operator applications, the 45 Series can be equipped with a control pattern selector valve. This allows you to change in seconds the excavators controls to the pattern you feel most comfortable with, either ISO or SAE.

The 45 features precise, light operating, hydraulic pilot operated joysticks with fully adjustable arm rests for total operator comfort and complete control. For operator convenience the excavator features a walk through design and for added protection the left hand control lever council swings up and engages a safety locking system which prevents unintentional operation of the joysticks.

The 45 features two speed travel which helps ensure maximum productivity. A foot pedal located on the floor of the operators compartment instantly and smoothly increases the excavators ground speed from 1.7 mph (2.8 km/h) to 2.9 mph (4.6 km/h).

When excavating along a wall the boom can be pivoted independent of the excavator housing . Operated by a foot pedal, the boom can be swung 80° left and 55° to the right. This feature allows you to dig in a straight line along a wall or dig a square hole without the need to reposition the excavator.

The 45 Series features a regenerative hydraulic circuit on the excavators dipper arm . Return oil from the rod end of the arm cylinder is ported through a check valve system to the base of the cylinder. This results in increased oil flow to the cylinder increasing arm speed, reducing cycle times and improving productivity.

To ensure cool running in all weather conditions the 45 Series is equipped with a high volume 15.9 gal. (60 L.) hydraulic reservoir and a high capacity oil cooler. This combined with a special return valve which ports hydraulic oil directly back to tank when operating attachments, such as hydraulic breakers, helps keep your hydraulic circuit cool and the excavator productive all day long.

The excavators drive system features a variable flow piston pump drive system . Unlike a gear pump drive which creates a constant parasitic load on the excavators engine the piston pumps automatically adjust both hydraulic flow and pressure to match the load demand. This results in both a quicker response as well as improved efficiency, reduced constant load demand on the engine and reduced fuel consumption.

Compact in size but big on total service accessibility. Open unobstructed space is what you find when you flip up the rear engine cover . For vandal protection the engine compartment door automatically locks when you close it. For ease of service the 45 is even equipped with a centralized lubrication system which makes swing frame lubrication a breeze.

The 45 comes fully equipped and ready for work with few, if any, add on options required . Half pitch rubber tracks for smooth ride, horn, work lights, a 15.2 gpm (57.5 L) auxiliary hydraulic system with boom mounted breaker piping, ROPS/FOPS 4 post canopy and toothed bucket are all standard equipment on the Thomas 45 Series.
