Overview
The PT40 is designed specifically to meet the needs of the experts in the machinery moving and rigging industry, its compact size and impressive capabilities also make it an excellent choice for moving heavy loads in manufacturing and heavy industrial applications. The PT40 has an impressive lift capability of 20 tons to a height of 20 feet.
Engine
- 91 hp at 3000 rpm
- 166 ft lbs at 1400 rpm
- Heavy-duty cast-iron block and head
- Spin-on fuel filter
- Dual element intake air filtration
The General Motors 3.0L four-cylinder engine runs on both gasoline and propane. By generating maximum torque at much lower speeds than the automotive engines, the PT40 operates at lower RPM, creating a quieter, safer working environment. A temperature-activated, variable speed cooling fan also minimizes noise while maximizing cooling. There are two engine speed control modes: a foot treadle for traveling, and a dash-mounted control for load handling.
Transmission
The Sauer hydrostatic drive is controlled by an adjustable foot treadle for variable 0-6 mph, forward or reverse travel. The large hydrostatic pump and deep-reduction planetary wheel hubs generate 20,000 pounds of tractive effort and will propel a 40,000-pound load up a 24% grade.
Hydraulics
At the heart of the PT40 is its intelligent hydraulic system. The pump is load-sensing and pressure-compensating with the ability to limit horsepower accordingly. This allows higher pump flows at lower pressure, or conversely, higher pressures without stalling the engine. The control valves are custom manifolds with industry-standard cartridge valves to greatly minimize hoses, adapters, leaks, and clutter. All the working elements of the valves are externally mounted on the manifolds, so there should never be the need to remove the entire valve for diagnosis or repair. And because cleaner oil is always better, the PT40 uses a 3-micron return filter and a pressurized reservoir to minimize outside air and moisture from entering the system.
