Pallet jack lowering control lever

The descent control lever is one of the core safety and control components of manual hydraulic pallet trucks. It is usually located on the handle assembly, and the operator can precisely and safely lower the fork and load, complete unloading or adjust the position of the goods by manipulating this lever.

Core functions and working principles

Control hydraulic circuit: The control rod is connected to the hydraulic cylinder release valve of the pallet truck through a mechanical linkage or wire. When the control lever is pulled backwards or downwards, the release valve will slowly open.
Controllable descent: The opening degree of the valve is controlled by the angle of the control rod, thereby achieving stepless speed regulation of the cargo from "fully locked" to "uniformly and slowly descending". This avoids damage or safety accidents caused by the sudden fall of goods due to gravity.
Safe locking: When not in operation, the control lever is usually fixed in the neutral/closed position by a spring or locking mechanism, ensuring that the hydraulic system is in a locked state and the fork does not accidentally descend.

Key Features and Design Points

Ergonomic design: The handle shape fits the hand, making it easy to operate and less prone to fatigue after prolonged use.
Clear gear/tactile feedback: Provides clear operational feedback, allowing the operator to perceive the descent speed through tactile feedback.
Durability: Made of high-strength steel or high-quality engineering plastics, it can withstand frequent use and impact in industrial environments.
Anti misoperation: Some designs include safety buttons or dual safety mechanisms that require lifting to activate, preventing accidental touches from causing descent.
Compatibility: The design needs to be perfectly matched with the hydraulic system and handle assembly of different models of pallet trucks.
