Advantage
1. Elevator-specific expansion anchors are the optimal product for installing elevator guide rails, brackets, clamping plates, and landing door devices, offering seismic performance, durability, and reliable delayed expansion functionality.
2. Rapid assembly and installation are achieved through thickened sleeves and oversized flat washers, delivering exceptional clamping force, making them ideal for heavy-duty facilities.
3. Elevator anchors maintain high load-bearing capacity and safety performance even in cracked concrete.
4. Generating zero expansion stress, these anchors achieve embedded effects via convex engagement within the conical hole, ensuring maximum anchoring reliability.
Application
Key Application Points for Elevator Anchor Bolts
1. Guide Rail Bracket Anchoring
Function: Securely fixes guide rails to concrete shaft walls or steel frames, bearing lateral forces and vibrations from car/counterweight movement.
Special scenario: Double anchor bolt density is required at curved rail sections and high-speed elevator rail joints to disperse impact loads.
2. Traction Machine/Main Drive Base Anchoring
Critical requirement: Resists motor start-stop torque, gear vibration, and emergency braking impact forces.
Expanded detail: Top-mounted machines in machine-room-less (MRL) elevators require combined tension-shear anchors to prevent overturning.
3. Control Cabinet & Machine Frame Anchoring
Added risk: Seismic displacement of control cabinets may cause electrical shorts, requiring earthquake-certified anchors (e.g., IBC/EN 1998 compliant).
4. Car Yoke Frame Anchoring
Dynamic loading: Inertial forces from car acceleration/deceleration transfer through supports, necessitating fatigue-resistant anchor design.
5. Counterweight Assembly Anchoring
Critical hidden points: Counterweight guide rail brackets and buffer bases (extreme case: buffers absorb 10+ ton impacts during car overtravel).
6. Safety System Critical Anchors
Overspeed governor base: Withstands instant impact loads during safety gear activation (anchor failure = safety system failure).
Safety gear bracket: Directly absorbs kinetic energy during car arrestment; requires highest-grade anchors (e.g., ETA certified).
Buffer base: Absorbs full kinetic energy during car bottoming (oil buffer reaction forces require specialized calculation).
7. Landing Door System Anchoring
Extended applications:
Landing sill brackets (endures passenger foot traffic + door operator traction forces)
Door header beam fixings (maintains door vertical alignment, preventing derailment)
Risk note: Loose sills create trip hazards, requiring closely spaced high-density anchoring.
8. Shaft Auxiliary Equipment
Cable brackets: Cyclic tension from traveling cable oscillation.
Ventilation/lighting supports: Vibration-resistant design for long-term operation.
Intermediate emergency stop devices (EN 81-20 requirement): Redundant anchor design.
9. Special Elevation Applications
Inclined elevators: Complex vector forces from slanted rails necessitate customized layouts.
Twin elevator systems: Mid-shaft support beams require anchors for superimposed loads.
