At Dynatect, we deliver innovative safety solutions that go beyond compliance, protecting people and productivity in every industrial environment.
Residual Risk Reduction (or R3) systematically identifies and minimizes remaining workplace hazards after existing controls are implemented. While OSHA establishes minimum safety standards, R3 goes further by proactively identifying and reducing residual risks even after those standards are met, creating a safer work environment beyond legal compliance.
Dynatect offers solutions like flexible guarding, articulating physical barriers, torque limiters, or machine safety controls to help reduce safety hazards associated with moving machinery parts and pinch points.
Machine guards are safety features, accessories, or systems designed to protect workers from injuries around hazardous equipment.
Types of machine guards include:
Machine guarding prevents contact with:
Benefits of machine guarding:
In addition to these benefits, OSHA regulations mandate fall protection for any opening exceeding two inches (see 1910.28 b for full details). This applies to inspection and machine pits. While guardrails and safety harnesses are options, walk-on duty retractable covers provide a more practical solution because they do not hinder access or require complex safety equipment. (e.g. Guard rails would need to be constantly removed and then put back in place.) This makes them an efficient choice for maintaining both safety and productivity.
Dynatect’s products help reduce risks in:
In the sections that follow, you’ll see how each safety category is brought to life with a specific Dynatect product or real-world application.
Separating Hazardous Processes from People & Equipment
The Gortite VF Automated Machine Safety Door is intended for machine guarding in automated work cells. Typical applications include automated production and machine processes that require preventive measures, such as robotic welding, processing, and transport tasks.
The safety interlock option meets PLE/Cat-4 safety requirements when combined with appropriate logic and conformance to risk assessment.
Additional safety features:
Large machine tools such as planer mills often are installed partially below floor level, resulting in potentially hazardous pits. Often, workers must remove pit grates or slats to service the machine. Here, metal roll-up, walk-on covers offer an alternative. Typically made of reinforced stainless steel, these covers allow partial pit access while preventing falls at other times or into other pit areas.
Dynatect’s walk-on roll-up covers create a continuous, protective, and walk-able surface that makes maintenance easy.
An aircraft manufacturer uses large fiber placement machines to build composite fuselages. These machines are designed with two stations, each equipped with adjustable tailstocks. The tailstocks move along guideways that are installed in a pit below floor level. Because production workers need to access the workpieces as they are produced, the pit must be covered during production for safety, but the covers also need to be removed easily for repairs and adjustments.
Traditional solutions such as grating or slats created challenges. Grating was time-consuming to move, and slats required complex support structures that made maintenance more difficult. To overcome these obstacles, the manufacturer chose Dynatect’s rugged walk-on roll-up metal pit covers.
The features of Dynatect’s walk-on roll-up covers include:
This solution improved safety by preventing falls into the pit and also enhanced operational efficiency by making maintenance faster and less complicated. The durability and ease of use of Dynatect’s design made it a practical choice for the demanding environment of aircraft manufacturing.
Roll-up covers can also be used to enclose chemical tanks and other vessels to contain fumes or prevent injury. These covers are not designed to support the weight of workers, so they are made of lighter materials such as polypropylene to withstand corrosive fumes. Wiper strips can keep the cover under tension and remove debris before retraction; electric motors and gear drives are employed in the take-up mechanisms.
Dynatect developed the ChemTank Cover in response to the demand for convenient and space-spacing chemical tank covers. Tank covers help contain evaporative emissions. The ChemTank is a corrosion-resistant roll up cover system that helps control heat and evaporation. It consists of a PVDF-coated PVC shade and compatible hardware for higher corrosive and higher temperature applications. With chemical and surface finishing processes in mind, the cover was designed for a wide variety of process tanks applications including chemicals, anodizing, etching, plating, cleaning and more.
Automated machines may experience unintentional obstructions, such as rotating parts or small access doors driven by a gear mechanism. Dynatect’s mechanical slip clutches have been added to systems to allow safer interaction.
In one such example, a slip clutch is part of a disabled-access system that automates a door’s opening and closing. The slip clutch allows obstructions to the operation without causing injury or damaging the drive motor.
In another application, a slip clutch was integrated into the driveshaft of a food prep machine’s rotating arm to add mechanical safety for the operator.
Scissor lift mechanisms, tilt tables, and similar equipment represent potential sources of injury because pinch points can be created when these mechanisms move. One way to protect against these hazards is to enclose moving parts with bellows that deter personnel from reaching into hazardous areas — yet permit machinery motion. Other benefits are improved machinery aesthetics and protection against dust, debris, and foreign objects.
Dynatect makes large-format bellows (“lift covers”) to cover the pinch points of lift tables or scissors mechanisms. In one iteration, heavy-duty accordion-type skirting is made from PVC/nylon and rigid aluminum extrusions with vented corners. The resulting rigid, moveable cover is suitable for lift tables and vertical-motion applications. Vents allow uniform airflow during operation, while optional maintenance straps allow for regular inspection and maintenance of the lift mechanism.
For applications necessitating lateral and linear motion, such as medical table bases, imaging tables, dental chairs, and amusement rides, bellows can be constructed using various materials and internal wires that maintain the necessary shape. Fabrication from a myriad of materials is possible, including some that meet UL burn standards or incorporate antimicrobial agents. Suitable for shear-type or lateral movement, the design’s compactness allows retraction into tight spaces.
Solutions include:
Large CNC machining centers require special effort to minimize the impact of dust and sound on surrounding work areas while still allowing access for loading and unloading large workpieces and tooling. In the examples shown below, a 5-axis machining center incorporates a retractable roof cover over its enclosure to answer both needs.
Do your production processes generate dust or small particles?
Machine roof covers were developed to contain debris and airborne contamination without creating interference or obstructions in the machining center’s travel.
For the ventilation of motors or engines in facilities or transportation applications (locomotives and railcars) rugged, flexible ducting is integral to the solution. Dynatect’s bellows / ducts/ motor-boots can be designed with materials available to meet regulatory compliance for flame, smoke, and toxicity (NFPA 130, EN45545)
Dynatect shade rollers are custom-made protective roll-up covers for machine guarding, consisting of coated or uncoated textile material attached to an industrial spring roller. Metal housing can be added to protect the roll-up mechanism. Shade rollers are a simple and cost-effective solution for involuntary contact with machine components.
