Henan Jinhuaiyu Machinery & Equipment Co., Ltd. is proud to introduce our Battery-Powered Tensioning Trolley Equipped With Electric Hoist – a next-generation solution designed specifically for bridge prestressing operations. This innovative trolley combines high-efficiency battery power with a reliable electric hoist, offering unmatched mobility and precision on construction sites. With our factory located in Zhengzhou, Henan, China, we have leveraged years of industry expertise to create a product that significantly reduces manual labor and enhances safety during tendon tensioning processes. The trolley is engineered to streamline your workflow, allowing operators to move and position loads effortlessly without the constraints of cables or external power sources.
Key Features and Benefits:
Battery-Powered Mobility: The built-in rechargeable battery system provides up to 8 hours of continuous operation, enabling free movement across the bridge deck without the need for trailing cables. This reduces setup time and eliminates trip hazards.
Integrated Electric Hoist: The trolley is equipped with a high-torque electric hoist capable of lifting and tensioning prestressing strands with precise control. Hoist capacity can be customized from 5 tons to 50 tons based on project requirements.
Wireless Remote Control: Operators can control both the trolley movement and the hoist functions from a safe distance using a wireless remote, improving safety and accuracy during delicate prestressing operations.
Robust Construction: The frame is fabricated from high-strength steel with a corrosion-resistant coating, ensuring long service life even in harsh outdoor environments. The trolley is designed to withstand heavy loads and repeated use.
Adjustable Tensioning Speed: The hoist features variable speed control, allowing for slow, precise tensioning or faster lifting when required. This flexibility helps prevent over-tensioning and damage to the tendons.
Easy Maintenance: All major components are modular and accessible, making routine checks and replacements simple. The battery is swappable, minimizing downtime on site.

Technical Advantages for Bridge Prestressing:
Precision Tensioning: The electric hoist is equipped with a load cell and feedback system, allowing operators to monitor tension in real-time, ensuring every strand is stressed to the exact required value.
Productivity Boost: By eliminating the need for manual winches and external power cords, the trolley can move quickly between anchor points, reducing cycle time by up to 40% compared to traditional methods.
Enhanced Safety: The battery-powered design eliminates the risk of electric shock from trailing cables, and the wireless remote keeps operators away from the load zone.
Versatility: Suitable for both post-tensioning and pre-tensioning applications on bridges, viaducts, and other large concrete structures. The trolley can be adapted for use with different strand diameters and anchor types.
Eco-Friendly: Battery operation produces zero emissions at the point of use, making it ideal for indoor or confined workspaces where ventilation is limited.

Frequently Asked Questions
Q: What is the battery life of the trolley under full load?
A: Under typical continuous operation at full load, the battery provides approximately 6–8 hours of runtime. Actual duration may vary based on load weight, travel distance, and hoist usage. The battery can be recharged in 2–3 hours using the included charger.Q: Can the trolley be used on slopes or uneven terrain?
A: Yes, the trolley is designed with a robust drive system and can handle gradients up to 5% on smooth surfaces. For rough terrain, optional all-terrain wheels are available. Please consult our sales team for specific site conditions.Q: What is the maximum tensioning force the hoist can apply?
A: The standard model offers a hoist capacity of 10 tons, but we can customize it up to 50 tons. The tensioning force is precisely controlled via the remote and can be set to any value within the rated range.Q: Is the trolley compatible with all prestressing systems?
A: The trolley is designed to work with most common strand diameters (12.7mm, 15.2mm, etc.) and anchor types. We can adjust the hoist attachment and trolley dimensions to match your specific system. Please provide details during ordering.Q: Do you provide training or installation support?
A: Yes, we offer remote training via video calls and provide detailed user manuals. For large orders, on-site training can be arranged at an additional cost.Q: What is the warranty period for this product?
A: We offer a standard 12-month warranty against manufacturing defects from the date of shipment. Extended warranty plans are available upon request.Q: How do I choose the right battery capacity for my project?
A: We recommend standard lithium-ion batteries for most projects. If you require longer runtime, we can upgrade to a higher capacity battery pack. Contact our technical team to evaluate your daily usage.Q: Can the trolley be operated in rainy conditions?
A: The electrical components are weatherproof with an IP54 rating, allowing operation in light rain. However, we advise avoiding heavy downpours to prevent damage. A protective cover is available as an accessory.
