Link-Belt 370LX Tier III, 4300 Quantum and 6000 Quantum specifications

The 370 LX working weight includes a specified front

Link-Belt's June 2011 Tier 3 brochure gives separate working weights for the Young three-piece and two-piece attachments. Both examples include the elevated cab, generator, specified magnet and track shoes. Neither is an attachment-free base-machine weight.

Match the front before comparing a transport quote with a brochure cover.

The lifting charts separate loading over the end from loading over the side. Their notes identify the side as the least stable direction and require lifting-accessory weight to be deducted. An asterisk marks a hydraulically limited chart entry.

A maximum reach alone does not establish a useful load at that reach.

Magnet operation changes the control discussion: the brochure disables selectable work modes and auto/one-touch idle during that operation. The grapple arrangement retains those choices. Determine which electrical and hydraulic package is installed before interpreting an unavailable control as a malfunction.

The boom-foot pin's extended lubrication interval applies to that particular connection. It does not give every attachment pivot the same interval. The brochure separately describes the grease-impregnated bushing and dust seals responsible for the boom-foot specification.

Why the Florida schedule describes a different base machine

The Link-Belt schedule preserved by Florida's purchasing department identifies a 370 LX MH base machine with an AA-6HK1XQB engine. The 2011 brochure instead identifies an AH-6HK1XYSS. Their published power figures differ.

Those documents cannot establish identical engine output for every machine carrying the 370 LX name.

The schedule explicitly excludes the complete attachment and conversion options from its base-machine description. The Young two-piece and three-piece fronts are separate selections. Generator and cab-riser packages have their own entries as well.

A base weight from that schedule therefore cannot replace the brochure's fully equipped working weight.

The order list also distinguishes taking no hose-burst option from purchasing the load-holding-valve option. Do not assume the valve package is present merely because a machine has a material-handling boom. Record the installed front, riser and valve equipment when comparing two listings.
