This document is a product manual for the TMG-DT4041C 40' x 40' Dual Truss Storage Container Shelter, manufactured by TMG Industrial. It provides comprehensive instructions for assembly, a detailed parts list, and important safety and maintenance guidelines.
Function Description:
The TMG-DT4041C is a robust, dual-truss storage container shelter designed to provide a covered space between two shipping containers. It is intended for industrial and commercial use, offering protection from the elements for stored goods, equipment, or as a workspace. The shelter is not intended for human occupancy. Its design, featuring a curved roof supported by a dual-truss system, ensures structural integrity and efficient shedding of snow and rain. The shelter is designed to be mounted on top of shipping containers, utilizing them as a foundation and sidewalls, thereby creating a large, enclosed area.
Important Technical Specifications:
- Model: TMG-DT4041C
- Overall Assembled Size:
- Width: 12 m / 39.37 ft
- Length: 12 m / 39.37 ft
- Height: 4.5 m / 15 ft (ridge peak height) + container height
- Shoulder Wall Clearance Height: 1.05 m / 3.4 ft
- Frame Structure: Dual truss system, comprising peak arch tubes, upper rafter tubes, lower rafter tubes, and sidewall tubes. The frame is constructed from steel, indicated by the use of hex bolts and nuts (M12x30mm) and self-locking bolts and nuts (M10x80mm) for connections.
- Cover Material: Roof fabric tarp cover (Part #17). The manual recommends taping or adding foam/rubber where the frame touches the cover to extend its lifespan, suggesting the cover is a fabric or tarp material susceptible to wear from friction.
- Tensioning System: Includes ratchets (3T), tie-down straps (W38xL800mm), cable connection plates (W90xL90mm), and ridge steel tension cables (φ8x3500mm) to secure the cover and enhance structural stability. Top cover tension tubes (φ32x1993mm and φ32x500mm) are also used for securing the cover.
- Base Plates: Baseplates for middle truss (W200xL340mm), and specific baseplates for front and rear truss left and right corners (W200xL340mm), indicating a secure mounting system to the containers.
- Purlins: Roofpurlins (horizontal tubes) (φ58x3040mm) provide lateral support for the roof cover.
- Accessories: Includes plastic hoses (φ25x4000mm) and connectors (φ25mm) for specific connections, tension tube end water plugs (φ32mm), and scratch-resistant tape (L10m) to protect the fabric cover from sharp points on the frame.
Usage Features:
- Dual Truss Design: Provides enhanced strength and stability, crucial for a large-span shelter.
- Container-Mounted: Utilizes standard shipping containers as a robust foundation and sidewalls, simplifying installation and maximizing usable space. This design also allows for easy relocation of the entire setup if the containers are mobile.
- Weather Protection: Designed to protect contents from various weather conditions, though specific wind and snow load ratings are not detailed in the provided excerpts. The manual emphasizes the importance of snow removal to prevent collapse.
- Modular Assembly: The structure is assembled from individual components (tubes, baseplates, purlins) using bolts and nuts, allowing for systematic construction.
- Tensioning System: The inclusion of ratchets, tie-down straps, and tension cables ensures the fabric cover is taut and securely fastened to the frame, preventing flapping and potential damage from wind.
- Ease of Installation (with caveats): While assembly requires careful attention to detail and adherence to safety protocols, the modular nature and clear instructions aim to facilitate the process. The manual explicitly states that assembly is difficult in heavy wind, suggesting a need for calm weather conditions.
Maintenance Features:
- Periodic Inspection: The manual strongly recommends walking around and inspecting the shelter periodically to ensure all components (bolts, nuts, connection points, base plates) are firmly secured and in good position.
- Cover Maintenance:
- Snow Removal: Crucially, snow accumulating on the fabric cover must be removed as soon as possible. The manual warns that solid ice accumulation increases weight and can lead to collapse or reduced lifespan. It advises against leaving snow on the roof overnight and maintaining a 3-foot clearance on all sides to prevent accumulation and inward pressure.
- Cleaning: The cover should be cleaned regularly.
- Protection: The use of scratch-resistant tape (Part #18) around sharp points of joints is a preventative measure to avoid friction between the fabric and the frame, thereby extending the cover's life. Taping or adding foam/rubber where joints connect and where the frame touches the cover is also recommended.
- Ground Conditions: The shelter should be kept on dry ground most of the time. The fabric dirt skirt should not be kept under water constantly to prevent deterioration.
- Rope and Tie-Down Adjustment: Ropes and tie-downs should be adjusted as required to maintain tension and stability.
- No Alterations: Users are advised not to make any alterations to the structure or hang weights on the frame during installation, as this can lead to damages or injuries and voids responsibility for the manufacturer.
The manual emphasizes safety during installation, recommending safety helmets, protective eyewear, appropriate clothing, safety harnesses for elevated workers, and proper ladder/cage operation. It also provides contact information for missing parts or assembly questions, reinforcing customer support.
