Assemblies designed for easy inspection of elevator and conveyor belts

Rub block door assemblies from Electro-Sensors provide early warning of conveyor or elevator belt misalignment, facilitating regular proactive maintenance inspections. The assemblies feature a hinged door, which allows for easy installation and access. 

Electro-Sensors offers three types of rub block door assemblies to meet various application needs. 

• The standard hinged rub block door assembly is designed for installation on most elevators and conveyors. It allows for quick and easy inspection of belts and replacement of worn rub blocks. Standard rub block door assemblies can be installed on new equipment or as a retrofit upgrade. 
• The adjustable rub block door assembly is designed for installation in difficult to monitor locations, such as enclosed conveyors or equipment with frames that interfere with optimum sensor mounting. This assembly has a hinged door with slots for attaching the rub block and sensor. After installation, the rub block can be slid approximately one inch into its sensing position so that belt misalignment can be quickly detected in previously difficult to monitor locations. 
• The uni-strut rub block door assembly is designed for installation on non-enclosed conveyors. The brass rub block is mounted on the side of the door facing the belt, and the assembly can be directly connected to the other side, allowing for easy vertical and horizontal adjustment of the rub block for proper belt misalignment monitoring. 

Electro-Sensors manufactures a complete line of motion monitoring and speed control systems for industrial machinery. Many of its products, including its rub block door assemblies, are available from Durham Instruments, a Pickering, Ont.-based distributor of high-quality electronic instrumentation and data acquisition and control systems across Canada.
