Zero-Max Overload Safety Devices Offer Options for Use in Difficult Applications

Comes in 2 models with sizes and options to fit level of needed protection

Zero Max Torq Tender Overload Safety Device

Zero-Max overload safety devices protect motor and drive systems from overload, while offering options to withstand corrosive environments and necessary washdowns. These options provide protection from direct water spray, washdown chemicals, detergents, chemical exposure, and debris.

Providing both torque limiting and coupling functions in a compact design, the overload safety devices can operate as a coupling and an overload safety device connecting two inline shafts in a power transmission system. They protect motor and drive systems from excessive overloading and potentially expensive system jam ups, especially after factoring in for equipment repairs, product loss, and any downtime incurred resulting from a jam up. They also offer easy re-engagement, allowing the system to be running again as quickly as possible.

Standard Torq-Tender overload safety devices have precision machined steel bodies with standard black oxide exteriors. Enhancement options for washdown and corrosion protection include: nickel-plated exterior with stainless-steel hardware for a moderate level of protection; stainless-steel exterior and hardware components for a higher level of protection; and O-ring seals added to seal between the driver and driven halves to provide added protection from exposure to water, chemicals, or debris. Lubrication options include food-grade grease and/or dry lube coating where needed. Special greases are available for specific application requirements.

Standard H-TLC overload safety devices have a robust composite body with plated hardware components that provide satisfactory protection for most applications. Enhancement options for washdown and corrosion protection include: stainless-steel exterior hardware components for a higher level of protection, stainless-steel springs that can be substituted internally, and food-grade grease. The H-TLC can also operate without grease in certain applications due to its robust composite construction.

Both Torq-Tender and H-TLC models are available in a variety of mounting configurations, including use as a coupling model or as a power take-off model for use with chain or belt drives. Actuating pin or actuating disc options are available for interfacing with a limit switch, proximity switch, or other sensing device to signal that an overload is occurring, or to shut down the drive motor when an overload occurs.
