The Sturdilite E-DC Series offers three DC models for haul trucks, hydraulic excava- tors, dozers and other mobile equipment. Each version is available at a highly competitive price with a short lead time: E36 (36 watts) up to 2,400 lumens, $131; E56 up to 4,500 lumens, $211; and the E90 up to 7,100 lumens, $299; (90W). The Sturdilite E-DC series uses LEDs with a 50,000-hour rated life and are capa- ble of operating in a wide temperature range. Spot and flood optics minimize glare and provide precise optical control. The 90° aimability allows for increased functionality and versatility. Split Roller Bearing Reduces Downtime Timken recently introduced its full Revolvo split cylindrical roller bearing housed unit line to the North American marketplace. The company added the Revolvo line, which is well-known across Europe, to its bearing and power trans- mission product lineup when it acquired the assets of Revolvo Ltd. late last year. The split design allows the bearing to be assembled around the shaft, which reduces downtime because drive compo- nents can remain in place during installa- tion or for maintenance. Compared with standard bearings, Revolvo-housed units can reduce installation time particularly in tight spaces and trapped locations com- monly encountered in such applications as fans, convey- ors, long shafts, crushers, etc. The product's design accommodates misalign- ment up to +/-1.5° and is available in a number of housing configurations including special pillow blocks, flanged, take-up and hanger assemblies. Servo Drive Offers Faster Commissioning for Large Machines Machine builders that traditionally have used separate servo drives to meet high axis-count and power requirements for large custom machines can now consoli- date to a single platform with the new Allen-Bradley Kinetix 5700 servo drive from Rockwell Automation. It offers dual- axis servos, a large 1.6-60 kilowatt power range, and time-saving tuning technolo- gy. Used in place of multiple servo drives, this next-generation platform can help machine builders reduce cabinet-space requirements by up to 70%, reduce wiring requirements by as much as 60%, and achieve easier configuration and commis- sioning. Pneumatic Hoists Allied Power Products added a new model line of pneumatic, radial piston powered hoists to its Columbia product line. The ini- tial introduction of these HS hoists includes models with line pull ratings of 3,500, 8,800 and 16,500 lb with hoisting speeds in excess of 100 ft per minute. These units feature heavy-duty cast construction and precision planetary reductions with all moving parts internally sealed to ensure full lubrication while minimizing service requirements. Rated to lift loads vertically, the HS Series of hoists utilize an automatic spring-set, pneumatically released brake. When used in conjunction with an optional counter- balance valve, operators can move loads quickly and smoothly with precise control. p r o d u c t n e w s c o n t i n u e d October 2015 43 Hitachi's newest rigid-frame haul trucks – the EH3500AC-3 and the EH4000AC-3 – are equipped with Hitachi's newest and most efficient Advanced IGBT AC-Drive system, which includes the Hitachi Drive Control System that reduces tire slippage on acceleration and tire lock-up during braking. The EH3500AC-3 and EH4000AC-3 have a nominal payload with standard equipment of 200 tons and 243.6 tons, respectively, and an operating weight of 709,888 lbs. and 846,575 lbs. The new haulers are two of the most technologically advanced mining trucks in the world, and help raise profits by lowering fuel and maintenance costs.
