Elevator Single-Line Rail Calibration Ruler SJT-56100, Magnetic Guide Rail Measuring Gauge for Elevator Maintenance Project

1. Product Overview
SJT-56100 is a portable guide-rail measuring tool integrating measurement, leveling, positioning and auxiliary fastening. Constructed of stainless-steel plate with aluminum-alloy high-strength magnetic blocks, it is equipped with high-precision spirit level and measuring scale. Fixed onto the end face of T-type guide rails by its L-shaped magnetic base, it performs guy-wire alignment measurement for guide-rail verticality, spacing and parallelism, quickly detecting rail offset to reduce faults such as car shaking and guide-shoe wear. Featuring magnetic-type design for quick assembly and disassembly, it requires no bolt-tight clamping and greatly improves on-site adjustment efficiency. Compatible with mainstream T-type guide rails of major elevator brands, it supports preliminary installation and alignment for passenger elevators, high-rise elevators and highspeed elevators. It caters to procurement needs of overseas elevator EPC contractors, foreign maintenance service providers and elevator spareparts distributors, and serves as a commonly-used measuring tool for elevator foreigntrade tool kits.

2.Core Product Features
• High-strength Magnetic Fixing: High-power magnetic blocks firmly attach to guide rails. No repeated bolt-tightening clamping required for fast assembly and disassembly.
• Stainless-Steel Ruler Body: Main body made of stainless steel with black oxidation treatment, resistant to site humidity and dust and resistant to deformation.
• Built-in Spirit Level: Integrated bubble level quickly establishes measurement reference and reduces manual measurement deviation.
• Laser-etched Metric Scale: Laser-etched markings are wear-resistant and non-fading for straightforward and clear readings.
• Multiple Versions Available: 6-magnet, 12-magnet and 18-magnet editions are available to satisfy diverse application requirements.
• Wide Compatibility: Compatible with mainstream T-type guide rails from major brands, suitable for preliminary alignment of passenger elevators, high-rise elevators and highspeed elevators.

4.Product Function Description
• Fast On-site Operation: Quick magnetic mounting, no tool-aided locking required. Ideal for new elevator installation, old-elevator overhaul and guide-rail displacement correction.
• Vertical & Horizontal Calibration: Fit the fixture against the working surface of the guide rail. Observe the spirit-level reading, adjust to the center position via the top fine-tuning bolt, then lock it in place.
• Reference Positioning: Adopt the extended scales and baffles on both sides to assist installers in quickly marking reference lines or mounting hole positions inside the hoistway.
• Snapline Assistance: Use the included wire spool to rapidly set plumb or horizontal lines within the hoistway. Combined with the built-in scale, it enables precise positioning for complex locations.
 
5.Precautions
• Handle with Care: Do not drop, strike or knock the ruler body and magnetic blocks. Deformed ruler or damaged spirit bubble will directly result in invalid measurement.
• Magnetic-surface Cleaning: Remove rust and dust from the guide-rail surface before attaching magnetic blocks to ensure firm adhesion and prevent falling off during operation.
• Keep Away from Electronic Devices: Keep high-strength magnetic components away from control cabinet circuit boards and sensors to avoid magnetic-field interference with electronic parts.
• Storage Requirements: Wipe clean after use and store in a dry place. Prevent magnets from long-term attachment to steel materials to avoid demagnetization.
