Safety pit covers
Bridge the safety gap
...and bolster facility safety with stable, low maintenance walk-on covers that move dynamically to allow access to the pit when you need it.
You can find them in most large manufacturing operations: big open chasms and deep pits built to hold heavy machinery or contain hazardous chemicals. The covering and securing of these huge hazards is vital for the safety of employees and the overall facility, but you don't want to make your equipment hard to reach.
For that reason, Hennig safety pit covers are the perfect solution. Because they are load-bearing and removable, you don't have to sacrifice safety for accessibility. They're the best of both worlds.
Regardless of the size of the area being protected, Hennig Safety Pit Covers easily endure constant use and (dependent on material) will support the weight of heavy chip loads and personnel.
Features and options
- 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)
For additional features and options, call us to discuss solutions best suited for your applications.

Frequently asked questions
Do pits in workplaces or workshops have to be protected?
The covering or securing of open pits is necessary for overall facility safety. The measures to protect against falls and falling objects include: Workplaces and traffic routes where there is a risk of employees falling or objects falling must be provided with protective devices that prevent employees from falling or being injured by falling objects. If protective devices against falls are not suitable due to the nature of the workplace or the work to be carried out, the employer must ensure the safety of the employees through other effective measures.
Which pit cover is the right one?
Depending on the requirements of your pit and the work area, the choice of material for your cover will vary. Our safety devices made of aluminum and stainless steel are stable and easy to care for, protect against damage and dirt, and are automated. Please contact us for your specific request.
