That steel plate covering your safety pit is a band-aid solution at best and a major liability at worst. You need something fit for function. Turn to Hennig for custom-made safety pit covers that ace safety audits and increase your usable footprint.
Foundries, automotive manufacturers and wastewater treatment plants trust our experience in heavy-duty applications.
Remove the guesswork and risk of buying a safety pit cover. Let Hennig handle the measurements, customization, and right-sizing for you. We back everything up with installation guidance or full onsite support, so your pit cover works from day one.
We cut our teeth on the toughest chips CNC manufacturing has to offer, so Hennig knows better than to standardize safety equipment around basic assumptions. Our engineers take time to understand your application and custom design pit covers that fit your shop for years.
The perfect pit cover for your shop depends on its application and environment. It may need to be aluminum or stainless steel, equipment load bearing or made for foot traffic.
Based on your application, we’ll recommend:
| Key Features | |
| Protective Canister | Protective canister housings can be provided to add protection to the roll-up covers gearing, spindle, and wound-up cover areas. |
| Walk-on Material | We offer stainless steel and aluminum covers. Because we choose the material based on the environment it operates in, our walk-on covers are always optimized specifically for your application. |
| Non-Slip Surface | A non-slip surface (anti-skid tape or paint) is added so that personnel may walk across the cover’s surface with greater safety than walking across slippery stainless steel or aluminum surface. |
| Actuation | Our walk-on covers are actuated one of four ways: air motor (regulates tension on the cover), electric motor, high-tension spring, no motor/passive (actuated by existing component on the machine). |
| Options | |
| Drive Options | Spring, compressed air, or electric motor |
| Material Options | Stainless Steel, AGS I, AGS II |
| Mounting Options | Over Cover Surface, Below Cover Surface, Angle/Custom Mounting |
| Assembly Options | Complete or partial assembly |
| Design Options | Rigid and movable designs available |
| Housing Options | Protection of drive, spindle, and winding area |
Not much, in most cases. Keep it clean and free of gunk and debris, and it’ll outlast all of us. Here’s a maintenance guide. You receive a guide for your specific cover with equipment delivery.
If you’re interested, the motor can be equipped with controls that identify any shifts in performance that may signal required maintenance.
Our engineers will ask a lot about your pit dimensions, work environment and desired functionality.
Hennig offers an installation service, or we can stay available to support your team, if you’re capable of installing the pit cover in house. Just let us know how hands-off you want to be when we’re quoting, and we’ll make sure we cover all our bases.
