FAQ
What is the difference between the Standard (HD) and Heavy Stack (HDG) configurations?
The Standard (HD) version comes with a 215 lb. weight stack, while the Heavy Stack (HDG) version includes a 240 lb. stack. The HDG is a great choice for facilities serving advanced athletes or powerlifters who need more resistance. Both versions share the same frame, adjustability, and features - the difference is purely in the amount of weight available.
Can I add more weight after purchasing the standard version?
Yes. HOIST offers an optional 5 lb. weight upgrade (part number RS-CAGE-NG-OPT3) that can be added to either version of the HD-3400. This allows you to fine-tune resistance increments for users who need smaller progression steps.
How does the self-aligning roller pad work?
The self-aligning roller pad is designed to automatically adjust to the user's leg position, helping ensure correct pad contact for both the leg extension and leg curl movements. This reduces the need for manual repositioning between sets and between different users, which is especially valuable in busy commercial gym environments.
How will this machine be delivered and does it require assembly?
Due to its size and weight (over 550 lbs.), the HD-3400 ships via freight on a pallet. Please contact us at service@omahasportsandgames.com to confirm delivery details, including whether white glove or inside delivery is available in your area. Some assembly may be required upon delivery.
What warranty does HOIST provide on this machine?
HOIST offers one of the best warranty policies in the fitness industry. The HD-3400 is warranted to the original purchaser against defects in workmanship and/or materials under normal use and service. For complete warranty terms and conditions, refer to the warranty documentation included with your machine or visit the HOIST Support page.
Is the HD-3400 suitable for home gym use?
While the HD-3400 is engineered for commercial environments, it is an excellent choice for dedicated home gym enthusiasts who want professional-grade equipment. Just be sure your space can accommodate the footprint (approximately 61" x 49") and that your floor can support the machine's weight. Its durability and adjustability make it a long-term investment whether in a home or facility setting.
