90 Manual Profile Warehouse

The 90 Manual Profile Warehouse supplied by Wanka Factory belongs to the category of manual heavy-duty shelving. It is different from the electric-driven profile storage racks. The entire operation system is driven by a hand-crank worm gear and worm wheel structure to move the gear rack and the screw rod, achieving the telescopic movement of the cantilever. The entire process does not require connection to external power lines. There are no electrical control components and no risk of circuit fire. It is the preferred vertical storage solution for explosion-proof workshops, factory areas without stable power supply points, and low-frequency material extraction scenarios.

Operation principle and human-machine operation experience

The entire telescopic extension and retraction power of the entire shelving system is supplied by manual hand cranking. The equipment is equipped with a hand-crank mechanism with a 1:60 transmission ratio. The operator only needs to apply a conventional hand force of about 150N to easily rotate the outer handwheel. The power is amplified by a worm gear reducer and then transmitted to the gear rack transmission pair, driving the cantilever to extend smoothly by 900mm to 1200mm. The 9-meter-long profile will follow the cantilever to move within the operation channel. Staff can directly complete the material retrieval and loading tasks using forklifts and crane trucks. After the material storage and retrieval operation is completed, reversing the handwheel can retract the cantilever to its original position.

The pure mechanical transmission structure operates smoothly with a low probability of jamming. Simple daily operations can enable one to master it. There are no common problems such as failure of the electronic control system or motor faults. The overall equipment has an extremely low inherent failure rate and a significantly reduced post-operation maintenance threshold.

Packaging and Shipping - Transportation Plan for the 90-Type Hand Cranked Profile Storage Rack

Due to the large size and heavy weight of the 90-type, special packaging and logistics design are required.

- Separate packaging: upright columns (each approximately 3.4 meters long), cantilevers (each approximately 1.8 meters long, 5-6 in total), base, hand-crank reducer assembly, gear rack, fasteners are packaged separately. The cantilevers are bundled with steel straps and grouped together. Each layer is padded with foam boards to prevent bumps. All steel components are sprayed with anti-rust oil and then wrapped with stretch film.

- Wooden box packaging: the hand-crank mechanism, reducer, small parts are placed in a non-pesticide-treated plywood wooden box (dimensions 1.2×0.8×0.6 meters), with waterproof bags and desiccants inside. The wooden box is sprayed with "fragile" and "upward" labels on the outside.

- Shipping method: domestically, 17.5-meter flatbed trucks are used. A single unit of the single-sided type can be transported, while a double-sided type requires 2 trucks or in batches. The total weight of the goods is approximately 2 tons (including packaging), and the logistics delivery time is 3-7 days (depending on the distance). Full GPS tracking is provided.

- Customer receipt: Please check for any damage to the wooden box and any obvious deformation or rust on the steel parts before signing for the delivery. If there are any issues, take photos and contact us within 48 hours for claim. After unpacking, count each item one by one against the packing list, and report any missing parts within 24 hours.

Frequently Asked Questions

Question 1: Can the 90 Manual Profile Warehous store 9.5-meter-long profiles?

Answer: The standard design is 9 meters. Beyond that, the cantilever strength is insufficient. If you need 9.5 meters, please choose a custom hand-operated profile warehouse (with an extended cantilever and increased wall thickness).

Question 2: Will operating the 5-ton machine by hand be very tiring? Can female workers operate it?

Answer: The manual force is approximately 150N, which is equivalent to lifting a 15-kilogram object. Men can handle it easily, and physically fit female workers can also operate it. If you want to be more efficient, you can choose a 1:80 speed ratio (customized), reducing the manual force to 110N, but increasing the number of rotations.

Question 3: Why use gear and rack instead of chain drive?

Answer: Gear and rack have greater load-bearing capacity, are more wear-resistant, and have no problem of chain slack. The gear module of the 90-style hand-operated profile storage unit reaches 8, and the rack is embedded in the bottom of the cantilever, providing good protection.

Question 4: Can it be installed outdoors in an open area?

Answer: Custom outdoor models are available. Main changes: Stainless steel rain covers are added to the handwheel and reducer, the gear teeth and rack are coated with weather-resistant lubricating grease, and all bolts are treated with Dacromet. It is recommended to build a simple canopy to extend the service life.

Question 5: I want to install an electric motor in the future to make it electric. Is this feasible?

Answer: The transmission structures of the manual type and the electric type are different (the manual type uses a worm gear and worm wheel, while the electric type requires a speed reducer motor and a clutch). The modification is very difficult and the cost is nearly the same as buying a new machine. It is recommended to determine the power mode before purchasing.

Question 6: Will the 9-meter-long shelf tip over?

Answer: The base width is 1.55 meters (on one side), and the depth reaches 9.5 meters (including the extension margin), and the anchor bolts are fixed to the ground. After anti-overturning calculation, in the most unfavorable condition (all cantilevers fully loaded and extended), the safety factor is greater than 1.8. As long as the anchor bolts are installed according to the drawings, there will be no risk of tipping over.

Question 7: Can the gears be replaced free of charge if they wear out during the warranty period?

Answer: Within 12 months, if there is severe wear due to normal use (if the tooth thickness decreases by more than 20%), they can be replaced free of charge. Damage caused by lack of oil or foreign objects entering is not covered by the warranty. Therefore, please lubricate them regularly according to the manual.

Question 8: How long is the delivery period?

Answer: The 90-style hand-operated profile storage unit is of standard size (not customized length). The production cycle is approximately 20 working days. If special colors or optional features are required, an additional 5 days will be added.

Question 9: Can you provide overseas export services?

Answer: Yes, we can. We have exported to countries such as Russia, Vietnam, and Indonesia. We offer export packaging, fumigation certificates, and origin certificates. The shipping fees will be quoted separately.

Real usage experience - Feedback from a customer in Chengdu, Sichuan Province

"We are a small steel structure processing factory, mainly producing 9-meter-long light steel keels. Our factory building is old and lacks three-phase electricity. We don't want to spend money on wiring. We bought the Wanka 90 Manual Profile Warehous. At first, we were worried that it wouldn't be stable, but after trying it, we found it very easy to operate. We store and retrieve about ten times a day, and we don't feel tired at all. Moreover, this thing doesn't require any maintenance at all, which is much more convenient than electric ones. Now the workshop is clean and safe, and even the customers who come to visit give it a thumbs-up." — Mr. Li, the factory director of a steel structure company in Chengdu, Sichuan Province.
