Holland USA has released the PH-210, PH-310 and PH-410 Series pintle hooks The three new models are significantly lighter in weight and have improved wear resistance for longer life, the company says. All feature a new, true one-hand latch operation with an automatic secondary lock and no chains or cotter pins. The new stronger latch design is more resistant to dirt and snow. Additionally, all three models come equipped with new air-chamber options with different plunger rod lengths, and are available without the air chamber and plunger or with the plunger alone and no air chamber. They can be used as an air-cushioned pintle hook or as a standard rigid unit without the air cushion.

The PH-210 and the PH-410 Series pintle hooks respectively replace their predecessors the PH-200 and the PH-400 Series. The PH-210
maintains the same 4-bolt mounting pattern and is rated for 18,000 lb maximum vertical load and 90,000 lb maximum gross trailer weight. The

PH-410 comes with a 6-bolt mounting pattern and is rated for 20,000 lb maximum vertical load and 100,000 lb maximum gross trailer weight.

The PH-310 Series is an all-new model that is made of the same steel alloy as the PH-210 with two key additions. First, the PH-310 is designed
with the popular six-bolt mounting configuration and secondly, it has increased capacities of 20,000 lb maximum vertical load and 100,000 lb maximum GVW.

The last new introduction is the PH-411, which directly replaces the former PH-400-H series. Again, the new more efficient mounting structure,
which matches the bolt pattern of the PH-400-H only requires six bolts instead of eight while still maintaining capacities of 20,000 lb maximum vertical load and 100,000 lb maximum gross trailer weight. The PH-411 incorporates all the new changes common with the PH-410.
