(1) Temporary electrical installations must be carried out in accordance with the relevant regulations and standards, and proper documentation must be maintained for internal records. This ensures compliance and provides a reference for future inspections or audits.
(2) A regular inspection system should be established for all temporary electrical lines and equipment on site. Detailed records of these inspections must be kept to ensure accountability and traceability.
(3) All temporary power distribution lines must be installed neatly and in compliance with safety guidelines. Overhead lines must be insulated, and the use of plastic cords is strictly prohibited. Lines should not be bundled, hung loosely, or laid directly on the ground.
(4) Construction equipment, vehicles, and workers must maintain a safe distance from both internal and external electrical lines. If the required minimum distance cannot be achieved, additional protective measures—such as barriers or shielding—must be implemented to prevent accidents.
(5) The distribution system must follow a hierarchical structure. All electrical distribution boxes and switchgear must be installed according to regulations, with reliable and functional components inside. The type and rating of the electrical devices must match the specifications, and each switch should be clearly labeled for its intended use.
(6) In independent electrical systems, a three-phase five-wire zero-connection protection system must be used as per standard requirements. For non-independent systems, appropriate grounding or zero-connection methods should be applied based on site conditions. All metal parts of electrical equipment and construction machinery must be properly grounded or connected to zero. Two-level leakage protection devices must be installed to create a complete and effective protection system. Leakage protectors must meet specific requirements, and all tall structures must have lightning protection as mandated.
(7) Handheld power tools must comply with national safety standards. Their power cords, plugs, and sockets should be in good condition. No unauthorized modifications, such as extending the cord, are allowed. The tool's outer insulation should remain intact, and a designated person must be responsible for maintenance and storage.
(8) When using 220V lighting in general areas, lamps must be wired and installed correctly, with a residual current device (RCD) installed on the power supply side. In special locations, low-voltage lighting fixtures must be used as required. For portable lighting, the voltage must not exceed 36V, and the lamp body and handle should be strong and well-insulated. Power cables must be made of rubber cables, not plastic wires. Transformer units for running lamps should have moisture and rain protection.
(9) Welding machines must have their own dedicated switches. The machine’s casing should be protected by either grounding or zero-connection. The primary cable length should be less than 5 meters, and the secondary cable should not exceed 30 meters. Connections on both sides must be securely crimped, and protective covers should be installed. The welding cable should be double-insulated, and no metal loops, scaffolding, rails, or structural reinforcements should be used as grounding paths. The welding cable must be undamaged and well-insulated. The installation area for the welding machine should be protected against moisture, rain, and flooding.

One of the key strengths of a Hydraulic Truck Winch is its exceptional pulling capacity. Capable of generating immense forces, it can handle the weight of large trucks and heavy - duty cargo with ease. In construction sites, it's often used to tow heavy machinery or move massive building materials. During off - road expeditions, when a truck gets stuck in deep mud, snow, or on rugged terrains, the hydraulic winch can provide a continuous and powerful pull, ensuring the vehicle can be retrieved without the risk of overheating or power failure that may occur with Electric Winches.​
Durability is another hallmark of hydraulic truck winches. Since they rely on hydraulic power rather than electricity, they are less susceptible to electrical glitches, making them highly reliable in harsh and wet conditions. They can endure long - term, continuous use without significant performance degradation, which is crucial for demanding jobs that require multiple recovery or hauling operations.​
The operation of a Hydraulic Truck Winch offers precise control. The hydraulic system allows for a gradual application of power, enabling operators to maneuver heavy loads with accuracy. This feature is especially valuable when handling delicate or unbalanced loads, reducing the risk of damage to the cargo or the truck itself.​
When it comes to the winch's components, both steel cables and synthetic ropes are commonly used. Steel cables are renowned for their high strength and abrasion resistance, making them suitable for rough and abrasive environments. However, they are heavy and pose a safety risk if they break under tension. Synthetic ropes, on the other hand, are lighter, easier to handle, and safer in case of breakage. They offer good strength - to - weight ratios but may be more vulnerable to UV damage and sharp edges.​
Selecting a Hydraulic Truck Winch requires careful consideration. The pulling capacity should be determined based on the truck's weight and the heaviest loads it is likely to encounter, with a general guideline of choosing a winch with a capacity at least 1.5 times the truck's weight. Additionally, the complexity of installation, which often necessitates professional expertise to integrate with the truck's hydraulic system properly, and the need for regular maintenance of hydraulic lines and connections to prevent leaks and ensure optimal performance, are important factors to keep in mind.​
