Kato Precision Railroad Models (関水金属株式会社, Sekisui Kinzoku Kabushikigaisha) is a Japanese manufacturer of model railroad equipment in N and HO scales. Founded in 1957, [1] the Tokyo-based company manufactures models based on Japanese prototypes (such as the Shinkansen bullet train and Cape gauge trains and locomotives) for the Japanese market, North American prototypes for the ...
The Kato wiring accessories (e.g. Unitrack DC Extension cord, Unitrack 3-Way Extension Cord) are sufficient to power layouts that are three tables in length. For very large layouts, there is an updated standard of using a wiring bus similar to that which was developed by the T-TRAK Division of the North Virginia NTRAK club.
Parts books were often issued as microfiche, though this has fallen out of favour. Now, many manufacturers offer this information digitally in an electronic parts catalogue. This can be locally installed software, or a centrally hosted web application. Usually, an electronic parts catalogue enables the user to virtually disassemble the product ...
A click torque wrench. A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.It is usually in the form of a socket wrench with an indicating scale, or an internal mechanism which will indicate (as by 'clicking', a specific movement of the tool handle in relation to the tool head) when a specified (adjustable) torque value has been reached ...
At stall, the torque converter can produce maximum torque multiplication if sufficient input power is applied (the resulting multiplication is called the stall ratio). The stall phase actually lasts for a brief period when the load (e.g., vehicle) initially starts to move, as there will be a very large difference between pump and turbine speed.
The EMD DDA40X is a 6,600 hp (4,943 kW) D-D locomotive, built by EMD from 1969 to 1971 exclusively for the Union Pacific Railroad. [1] It is the most powerful diesel–electric locomotive model ever built on a single frame, having two 16-645E3A diesel prime movers. [2]
Stall torque is the torque produced by a mechanical device whose output rotational speed is zero. It may also mean the torque load that causes the output rotational speed of a device to become zero, i.e., to cause stalling. Electric motors, steam engines and hydrodynamic transmissions are all capable of developing torque when stalled.
A torque limiter is an automatic device that protects mechanical equipment, or its work, from damage by mechanical overload. A torque limiter may limit the torque by slipping (as in a friction plate slip-clutch), or uncouple the load entirely (as in a shear pin). The action of a torque limiter is especially useful to limit any damage due to ...
