A GPU provides electricity to an aircraft when:

• it is parked at the gate or on the apron,
• the engines are turned off,
• ground crews want to avoid using the aircraft’s fuel.

It powers systems such as:

• cabin lighting
• avionics and onboard computers
• air conditioning
• maintenance systems

FB70077-1 is a part number used in aviation ground support equipment — specifically for engine handling/transport stands used with certain aircraft engines (not a typical workshop tool).

• Provides a stable base/frame for mounting a CFM56 engine cradle or transporting the engine securely on the ground.

• Used by airline maintenance crews (MRO), engine overhaul facilities, and aircraft manufacturers.

The Pullmax P-21 is a heavy-duty industrial machine designed for sheet metal fabrication, commonly used in metalworking, manufacturing, and workshop environments. It is part of the Pullmax series of reciprocating metal shaping machines built originally by Pullmax for a variety of cutting and forming operations on metal sheets.

• Industrial Nibbler / Shearing Machine: The P-21 model is typically referred to as a nibbler, which means it mechanically cuts sheet metal by producing small, quick cutting actions rather than slicing in one continuous motion.

• Metal Fabrication Use: It is designed for cutting, shaping, and forming metal sheets with precision.

• Variable Speed & Adjustable Settings: On examples seen by dealers, the machine can have variable speed settings (up to around 1500 strokes per minute) and adjustments for stroke and tooling height—features that help adapt it to different metal thicknesses and cutting needs.

• Large Work Capacity: Many P-21 machines have a sizeable throat height, allowing larger workpieces to be processed.

• Square Tooling Interface: It uses standard Pullmax square-shank tooling (the P-21 shares a 19 mm tooling size with other Pullmax models).

Typical Applications:

• Cutting and nibbling complex shapes in sheet metal

• Producing holes or cut-outs without bending or distorting nearby material

• Working with medium and heavy-gauge metal stock

TOWE170-C-4 is a specialised aviation ground support tool known as a towbar assembly. It’s used to move and position aircraft on the ground by connecting the aircraft’s nose gear to a towing vehicle.

• Type: Towbar Assembly (tool for aircraft ground support).

• Purpose: Designed to tug aircraft like the Embraer 170 family during push-back, taxiing in hangars, repositioning on the ramp, and other ground movements.

How It Works

In airport operations, a towbar like the TOWE170-C-4 connects the landing gear of the aircraft to a ground vehicle (tug). The operator steers and maneuvers the aircraft safely without engaging its engines. This helps with push-backs, repositioning, or towing into maintenance areas.

Typical Use Cases

• Ground handling at airports

• Aircraft repositioning on ramp or hangar floors

• Maintenance and servicing moves

• Safe connection between aircraft and tug
