Crane Hoist Line Speed and Power Test Procedure

2017-06-07
CURRENT
J820_201706
This document applies primarily to mobile cranes that lift loads by means of a drum and hoist line mechanism. It can be used to determine the hoist line speed and power of other hoist line mechanisms, if the load can be held constant and hoist line travel distance is sufficient for the accuracy of the line speed measurements prescribed. This recommended practice applies to all mechanical, hydraulic, and electric powered hoist mechanisms.

Counterfeit Electronic Parts and Their Impact on Supply Chains

2014-10-20
Electronic parts are used throughout industry to run everyday products, such as cell phones, and also highly technical products, such as aircraft, missiles, and spacecraft. Unlike cell phones, which are often replaced every year, the highly technical products may remain in service from 20 to more than 80 years. But what happens if the original electronic part, with a life cycle of 18 months, is no longer available? Some manufacturers have discovered that they have unwittingly purchased counterfeit ones. Counterfeit Electronic Parts and Their Impact on Supply Chains examines how these items are negatively affecting the aviation, spacecraft, and defense sectors and what can be done about it.

OEM/Vendor Interface Specification for Vehicle Electronic Programming Stations

2000-08-28
CURRENT
J1924_200008
The purpose of the SAE Information Report is to address the method of loading vehicle electronic controllers with chassis and customer specific parameters. This specification shall establish an interface definition. The interface definition must be mutually agreeable to truck OEMs and vendors. The purpose of this specification is not to answer the large protocol issues raised by systems such as GM's MAP. SAE Standard In the future, SAE may use this specification as a basis for an OEM/Vendor interface specification standard.

Air Brake Valve Input-Output Characteristic Requirements

2016-06-17
CURRENT
J1861_201606
This SAE Recommended Practice establishes minimum tolerance requirements for pilot operated and mechanically actuated modulating type valves, and through type valves used in the service brake control system when tested in accordance with the test procedure outlined in SAE J1859. This document applies to the nominal input-output characteristics as specified by vehicle original equipment manufacturer and labeled by the valve manufacturer as outlined in SAE J1860. The tolerance requirements will include: a Crack (opening) pressure or force. Crack pressure may be measured at the initial output pressure or as the pressure differential before output pressure exceeds 14 kPa (2 psi). Crack force may be measured at initial output pressure or before output pressure exceeds 14 kPa (2 psi). b Pressure differential (input-output)

Hybrid and Electric Buses and Taxis 2013-2023: Forecasts, Opportunities, Players

2014-01-01
This is the world's first report forecasting the global market for electric buses and taxis both hybrid and pure electric. It separately forecasts the market in the most important area, China, and it takes a detailed look at technologies present and future with a blunt assessment of reasons for failure and threats for the future. The market for electric buses and taxis will multiply over 8 times in the next decade, approaching $60 billion not long after that. China will become by far the largest market for both electric buses and electric taxis within the decade. This report looks at the statistics and trends for conventional buses and taxis, the government incentives, paybacks and new technologies with detailed tables and figures to summarize the situation, so the reader can understand the situation with ease.
