How much does the Hartford HSA-427EAY cost?
Price estimate
We do not have a price for the Hartford HSA-427EAY that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Hartford HSA-427EAY has the longest Y travel of the 12,000 kg four-metre models: 3,500 mm (137.8 in), over a table of 4,000 x 2,200 mm (157.5 x 86.6 in). X travel is 4,000 mm (157.5 in). The load rating of 12,000 kg equals 26,455 lb.
Put the figures side by side and the design intent is clear. Table width is 2,200 mm, Y travel 3,500 mm. The spindle can move a long way past each edge, far enough to carry an extended tool in an angular head and still back clear of the workpiece. For mould bases with deep cooling holes or frames with cross-bores, that is the working margin.
On the plain EA version, the HSA-427EA, Y travel is 2,700 mm (106.3 in). The intermediate choice is the HSA-423EAY at 3,100 mm (122.0 in).
Hartford's page for this model lists DDS among the spindle choices, and the spec table shows a #50 gear head at 6,000 rpm, an 8,000 rpm option and a hybrid built-in spindle at 10,000 rpm, with 18.5 / 22 kW or optionally 30 / 35 kW. The Z axis has 1,000 mm of travel, 1,200 mm as an option, and four linear guideways.

Frequently Asked Questions
01
3,500 mm (137.8 in). The table is 2,200 mm (86.6 in) wide, so the spindle travels well beyond both edges. X travel is 4,000 mm (157.5 in) and Z travel 1,000 mm or 1,200 mm.
02
Same table, same 12,000 kg rating, same spindle rows. The HSA-427EA has 2,700 mm (106.3 in) of Y travel and the HSA-427EAY 3,500 mm (137.8 in).
03
12,000 kg (26,455 lb). If the parts are heavier, the HSA-428EAY carries 18,000 kg (39,683 lb) on a 4,000 x 2,500 mm (157.5 x 98.4 in) table.
04
