Door Lock for Dingli Sinoboom Scissor Lift For Dingli Sinoboom Scissor Lift Repair and Maintenance

Product Overview: Scissor Lift Door/Gate Lock Assembly

This product is a replacement Door Lock Assembly or Gate Latch designed for scissor lifts manufactured by Dingli and Sinoboom. It is a critical safety component that secures the entry gate of the lift platform, ensuring the operator remains safely within the platform during movement and operation.

Primary Function:
To reliably lock the platform door or gate, preventing accidental opening and ensuring operator safety in compliance with ANSI/SAIA A92.20 and other international safety standards for MEWPs (Mobile Elevated Work Platforms).

Key Features & Components:

The lock assembly is engineered for durability, safety, and ease of use. Key characteristics include:

• Robust Construction: Typically made from hardened steel or zinc-alloy die-cast to withstand high-impact forces, frequent use, and harsh job site conditions.

• Corrosion Resistance: Often features a protective finish, such as yellow zinc plating or electrostatic powder coating, to resist rust and corrosion from outdoor exposure.

• Positive Latching Mechanism: Provides an audible and tactile "click" to confirm the door is securely locked. The mechanism is designed to resist vibration-induced loosening.

• Safety Interlock Compatibility: Many models are designed to integrate with the machine's safety interlock system. This system can prevent the lift from driving or elevating if the gate is not properly locked.

• Easy Actuation: Features a large, ergonomic handle or latch that is easy to operate, even while wearing work gloves.

• Direct OEM Replacement: Designed to match the original part's dimensions, mounting hole patterns, and functional requirements, ensuring a perfect fit and correct operation.

Compatibility & Application:

• Manufacturer Compatibility: Designed for scissor lifts produced by Dingli and Sinoboom.

• Machine Type: Electric and Rough Terrain Scissor Lifts.

• Application: This lock is used on the platform entry gate or door. It is a crucial part for routine repair and maintenance to maintain the structural integrity and safety of the lift platform.

Purpose & Importance:

This component is not just a convenience item; it is a vital safety-critical part. Its proper function ensures:

• Operator Containment: Prevents the operator from falling from the platform.

• Regulatory Compliance: Helps keep the machine compliant with workplace safety regulations.

• System Integrity: A faulty lock can disrupt the entire safety interlock system, rendering the lift inoperable until repaired.

Common Reasons for Replacement:

• Wear and Tear: The latch mechanism becomes loose or fails to engage securely after extensive use.

• Physical Damage: Bent, cracked, or broken components due to impact or misuse.

• Corrosion: Seized or stiff operation caused by rust, especially in environments with high moisture or exposure to corrosive elements.

• Failed Safety Inspection: The lock is identified as defective during a routine pre-start inspection or periodic maintenance check.

Installation Note: For safety and warranty purposes, installation should be performed by a qualified technician. It is crucial to verify the specific Dingli or Sinoboom model number to ensure part compatibility, as lock designs can vary between different lift models and series. After replacement, the safety interlock function must be tested to ensure it operates correctly.
