The 416D has a digging depth of 14 ft. 5 in. with the standard stick and 18 ft. 1 in. with an extendable stick. The 420D has a backhoe digging depth of 14 ft. 5 in. when equipped with the standard stick while the 430D has a digging depth of 15 ft. 3 in. with a standard stick. Extendible sticks push the 420D''s dig depth to 18 ft. 1 in. and 19 ft. 11 in. for the 430D. All three machines now feature 205[degrees] rotation dakedrillpress of the backhoe bucket linkage, 40[degrees] more than the C-Series machines. "This new design feature makes it easier to dig vertical walls and to clamp material for truck loading," said Hershberger. In addition, the backhoe buckets now feature single pin position and all former models'' buckets and Cat work tools can be used on the D-Series. The bucket link now has an integrated lifting eye.

Keith/U.S. Tsubaki: The overall costs of a locking device must be balanced against the requirements of the application. Keyless locking devices handle both high torque and thrust, while increasing shaft strength. They are not affected by torsional load reversal or impact, which can damage keys and keyway connections.Jeff/Tollok: One commonly mentioned advantage of keyless connections is that no secondary processes are necessary. The mechanical interference fit principle of a keyless locking assembly precludes having to cut keyways, tapers, splines, or threads. dakedrillpress A straight cut hub with a good surface finish by a machine tool is sufficient. Assembly and disassembly is easy and quick, and angular adjustments can be carried out on the spot. And because the connections are backlash free, you don''t need to compensate for mechanical inefficiencies elsewhere in your machine or controls system. It was a quiet Tuesday morning, about IS minutes before opening the shop doors. All the techs were busy performing their morning rituals -- drinking coffee, reading trade publications and oiling their air tools. Without warning, our otherwise tranquil morning was interrupted by a horrendous screech of brakes as a late-model, metallic-blue BMW M3 slid into the service drive. Steam was billowing out from underneath the engine compartment. The driver, a moderately dakedrillpress dressed, thirty-something suburbanite, jumped out and opened the hood. Instantly, a huge white cloud engulfed him and the entire front half of the car. I fully expected that when the fog cleared, at least one of them would have vanished -- like a magician''s disappearing act.
