Engineered to Prevent “Door Sag” in Wide Access Points
The most common failure mode for industrial gates, especially those wider than 1 meter, is structural fatigue at the hinge points. Gravity takes its toll, and eventually, the latch bolt no longer aligns with the striker. This is a nightmare for maintenance access and can render sophisticated robot work cell safety interlocks useless.
Our Hinged Door systems are specifically designed to combat this physics problem. As shown in the double-door configuration above, we integrate heavy-duty caster wheels on the outer edge of wide door leaves. This simple yet effective addition transfers the weight load from the post to the floor, eliminating torque on the hinges. Combined with our rigid framed panels made of Q235 carbon steel, this design ensures that the door remains perfectly level for years, regardless of how many times it is cycled by operators loading assembly systems.
Precision Alignment for Sensitive Safety Interlocks
Modern machine guarding relies on precise electronic components. RFID switches and tongue-actuated interlocks require alignment tolerances of just a few millimeters. A wobbly fence door makes achieving this impossible.
Our system includes a dedicated overhead door frame beam (Door Header) that rigidly connects the two door posts. This prevents the posts from bowing inward or outward, maintaining a constant gap width. As illustrated in the installation guide, every component—from the door stop to the door handle—is modular and adjustable. This allows your installation team to fine-tune the fit on-site, ensuring that the “handshake” between the physical door and your control equipment is always solid, satisfying both ISO 14120 standards and your client’s uptime requirements.
Built for the Rough Reality of Material Handling
Doors are the interface point between human operators and custom machinery. They are slammed, kicked open, and occasionally bumped by carts in the material handling area.
We use 40x60mm heavy-duty hinges and full-frame construction (20x30mm steel tube) to withstand this abuse. Unlike frameless wire doors that can bend and become sharp hazards, our doors maintain their shape and safety integrity. By investing in a high-quality industrial safety fencing door system, you reduce the Total Cost of Ownership (TCO) for your client by minimizing the need for constant adjustments and repairs by their maintenance team.
Frequently Asked Questions
1. How do you prevent wide doors from dragging on the floor?
For doors exceeding a certain width (typically over 1000mm), we provide a caster wheel kit that mounts to the bottom of the door frame. This supports the weight of the door, preventing hinge sag and ensuring smooth operation.
2. What is the maximum width for a double hinged door?
Our standard double hinged door system can cover an opening of up to 3000mm (1500mm per leaf). This provides ample clearance for forklift access or moving large machinery components in and out of the cell.
3. Does the door system come with a header bar?
Yes. All our door kits include a yellow top header bar (door frame beam). This is a crucial structural element that ties the gate posts together, ensuring they remain parallel and stable for consistent lock alignment.
4. Can the doors swing in both directions?
Standard installation is for 180-degree opening in one direction (outward or inward), controlled by the door stop. However, the hinges allow for flexibility, and the opening direction can be determined during assembly on site.
5. Are the handles and locks reversible?
Yes. Our modular design allows handles and lock mechanisms to be installed on either the left or right side, giving you full flexibility to adapt to the specific traffic flow and ergonomic needs of your production line layout.
