ProMaxima Raptor P‑4400 Weight Assisted Chin‑Up (P‑4400)

Overview

The ProMaxima Raptor P‑4400 is a selectorized, weight‑assisted chin‑up/dip station engineered for safe progression and high throughput in schools, PT studios, and full commercial gyms. A padded knee platform offsets bodyweight while entry steps and multi‑position handholds help users set up quickly.

The 225‑lb weight stack adjusts in 5‑lb steps via a tethered magnetic pin. Full‑length shrouds, commercial‑grade cables, and sealed bearings deliver smooth operation and long‑term durability.

Description

The P‑4400’s knee platform counterbalances bodyweight to create an instantly scalable workload—select more weight for greater assistance or less weight as strength improves. Natural‑rubber handgrips provide secure holds for both chin‑up and dip patterns, while the chin‑up station swings out of the way when not in use to maximize clearance.

Built for longevity, the frame uses ASTM A‑500 grade B structural steel and a multi‑stage powder coat. Commercial cables route through fiberglass‑reinforced pulleys with sealed bearings, and on‑machine tension adjusters keep the motion crisp over time.
