In the modern logistics and warehousing industry, loading and unloading safety is of Paramount importance apart from efficiency.
When trucks are performing loading and unloading operations on the platform, even the slightest movement can cause the loading and unloading platform to shift, the goods to tilt, and even lead to injuries to the handlers.
An accident not only may cause casualties but also slow down the progress of loading and unloading goods, resulting in double the impact.
The vehicle restraint was invented precisely to avoid this situation. The anti-collision bar at the rear of the truck is clamped by a rotary hook. To keep the truck stable during loading and unloading and prevent it from moving.

Our company, YUOU Door Industry, has newly launched an electric fixed smart car lock. This is a safety protection device specially designed for warehousing and logistics centers, dock levelers.
It adopts a combination of mechanical drive and electronic control systems. By automatically locking the hook to secure the anti-collision bar of the truck, it achieves efficient and safe loading and unloading management.
The dock lock is controlled by a dedicated control box. It is also equipped with signal indicator lights to assist truck drivers in determining whether the vehicle lock is working properly.


15,000kg strong locking force: Provides a powerful fixing force to prevent any slippage or displacement.
420mm adjustable height: Adapted to the rear height of different vehicle models, providing more precise locking.
Thickened high-strength lock hook: 30mm thick steel lock hook, wear-resistant and durable, anti-deformation.
Signal indicator light system: The traffic lights clearly display the locked status, making operation straightforward at a glance. Reduce the operational difficulty and accident rate.
PLC intelligent control and multi-device linkage interface: The controller can be connected to other devices. It can be controlled synchronously with the dock leveler and the lifting door.

The vehicle restraint effectively prevents vehicles from leaving their positions during loading and unloading through an automatic detection and precise locking mechanism. Ensure that the forklift or staff can smoothly enter and exit the vehicle box before the work is completed.
Secondly, drivers can clearly understand the loading and unloading status through the signal lights. Operators can carry out safe operations under system prompts. External traffic lights: A red light indicates that the car lock is working, and a green light indicates that the car lock has been unlocked and you can leave. The driver observes the working status of the car lock through the rearview mirror of the vehicle. The built-in signal lights on the indoor control box enable the indoor staff to determine the working status of the car lock.
This intelligent protection not only enhances work efficiency but also fundamentally reduces safety risks.
