Handbook of Assembly and Commissioning of the Stepless Holding Brake (SHB)

Product catalog summary
General Information
The document provides operating instructions for the Stepless Holding Brake (SHB) by LEANTECHNIK AG, covering sizes 5.0 to 5.3. It emphasizes the importance of following instructions to prevent malfunctions or damage.
Safety
Safety symbols and personnel requirements are outlined to prevent injuries and property damage. Only qualified personnel should handle the brakes, and all relevant safety standards must be observed. The brakes are not suitable for explosive atmospheres.
Legal Provisions
The document lists applicable standards such as EN ISO 4414 and EN ISO 13849-1. Liability is limited if instructions are not followed, and warranty conditions are specified.
Product Description
The SHB is a pneumatically actuated, spring-applied brake designed for profile rail guides. It operates on a fail-safe principle, clamping the rail when depressurized.
Technical Data
Key specifications include an ambient temperature range of -10°C to +60°C, protection class IP44, and a maximum sliding speed of 2 m/s. The nominal holding force varies with pressure, e.g., 3000 N at 6 bar.
Correct Use
Instructions for proper use, limitations, and foreseeable misuse are provided. The brake must be used within its technical specifications.
Installation and Commissioning
Guidelines for storage, installation, and commissioning are included. The brake must be tested before and during operation to ensure functionality.
Maintenance
Regular inspection and maintenance are necessary to ensure the brake's longevity and performance. Cleaning procedures are also outlined.
Disassembly and Disposal
Instructions for safely disassembling and disposing of the brake are provided.
Malfunctions
Common malfunctions and troubleshooting steps are listed to assist in resolving issues.
Technical Specifications
The document provides detailed technical specifications for the braking system, including dimensions, weight, and performance metrics. The system operates within an ambient temperature range of -10°C to +60°C and uses compressed air as the pressure medium, adhering to ISO 8573-1 class 4 standards.
Procedures and Usage Instructions
The document outlines the correct use of the braking system, emphasizing the importance of using the brake with a guide rail to prevent damage. It includes instructions for static and dynamic applications.
Limitations and Misuse
Several limitations are noted, including the unsuitability of the brake for use in liquid media, vacuum, or contact with abrasive and corrosive substances.
Installation Guidelines
Installation instructions emphasize the importance of using the brake with the correct profile rail and ensuring all components are properly connected and secured.
Storage Recommendations
Brakes should be stored in dry, dust-free environments with controlled humidity and temperature.
Safety and Maintenance
Safety-related applications are discussed, recommending the use of proximity switches and pressure monitors for enhanced safety.
Calculation Example
An example calculation for dynamic braking is provided, illustrating how to determine the required holding force and stopping distance.
Installation and Safety Precautions
Installation involves fastening screws without applying torque, using Loctite 243 for screw locking, and ensuring the brake is only closed with the guide and pushed onto the profile rail.
Switch Condition Monitoring
Proximity switches emit signals for brake condition changes, requiring a plausibility check of signals.
Commissioning and Testing
Before commissioning, check all fastening screws and inspect pneumatic connections for leaks. Regular brake force checks are recommended.
Maintenance and Inspection
The SHB is designed for up to 200,000 switching operations and is largely maintenance-free. Regular inspections and cleaning of the profile rail are necessary.
Disassembly and Disposal
Disassembly should follow the reverse order of installation. Disposal must adhere to country-specific regulations.
Malfunctions and Troubleshooting
Common issues include inadequate ventilation, braking, or release, often due to low operating pressure, faulty valves, or worn components.
