Residential Deliveries

Free Shipping via UPS SurePost is an economy, residential, ground service. This service combines the consistency and reliability of the UPS Ground network with final delivery typically provided by the U.S. Postal Service. If you wish for your order to go through UPS for delivery, select UPS Ground at checkout.

Freight companies could charge an additional fee on top of the original freight charge if delivering to a residence. Each freight carrier has its own definitions for residential delivery.

Freight

BH-USA will make every effort possible to find the most cost-effective freight shipping method for your order. The customer is financially responsible for all shipping and handling charges of their order. BH-USA will select from one of its preferred freight carriers to ship your order unless otherwise specified in writing.

The customer must work with the freight carrier for delivery. Two options; pick up at the terminal or deliver to a location. Freight carriers will not unload and drop freight at the door like UPS or USPS. The freight carrier will make every effort to arrange delivery with the homeowner. If the customer is uncompliant with the freight carrier, the order will be returned to BH-USA. The purchaser will be charged for all freight costs and an additional 20% restock fee.

BH-USA is in no way responsible for any type of issues with the delivery of freight such as gates, neighborhoods that do not allow large trucks, inaccessible roads, homeowner being out of town, or any other issue that might hinder the delivery of the freight.

BH-USA cannot promise any special requests from a customer regarding freight, this must be handled between you and the freight company. If you are concerned that a large truck cannot deliver to your address we suggest not ordering this item until you have made arrangements to have it shipped to a commercial address.

Freight Quotes

We are here to help if you need a freight quote. BH-USA will quote based on information supplied by the customer at the time of the quote.

BH-USA will not be held responsible for this quote if unforeseen charges are applied. Such charges could be a residential delivery charge, drop gate, missed delivery attempts, or other types of charges. If this happens, BH-USA will bill the customer for the additional charges with the payment method used to place the order. BH-USA reserves the right to run the credit card provided again for the additional freight charges.

Due to the fluctuation of fuel costs, all quotes are considered an estimate. Charges could be higher than previously quoted on the order. The customer is responsible for the cost difference.

Receiving a Freight Shipment

Signing the delivery ticket as received is a contractual agreement transferring ownership of the shipment from BH-USA to the signee.

BEFORE you sign the delivery ticket make sure delivery is complete and no visible damages are present. If items are missing or damaged either notate this on the delivery ticket. Have the delivery driver sign the notation or refuse the shipment.

If the shipment is delivered and signed it is complete delivery. Then it is understood by BH-USA that the shipment arrived complete with no damage or issues.

Filing a Claim

BH-USA will help with the claim process. It is the responsibility of the customer to file the claim with the shipping carrier. BH-USA is not responsible for replacing any missing item that was lost in transit and signed as received by the customer. Once a claim is approved by the shipping carrier, BH-USA will send a replacement item.

Please note that most shipping carriers will not approve a claim if the customer has signed received it in full. BH-USA is not responsible if an unauthorized person signed for the shipment with missing or incomplete items.

Incorrect Order Shipped

If BH-USA is at fault for shipping the wrong item or amount, we will reship the item(s) at our own expense. The correction will process like other orders and follow standard BH-USA shipping procedures.

Claims for shortages or unseen damages MUST be made within 10 days of receipt of shipment.

BH-USA will arrange the wrong item(s) return at our expense. If the wrong item is not returned within 10 days of the claim, the customer will be billed for the item.

BH-USA reserves the right to select a carrier for any shipment that qualifies for prepaid freight. BH-USA will not prepay overnight, next-day air, second-day air or priority shipments regardless of the situation.

Call Tags

Only one call tag issued when picking up items sent by mistake. The customer will be billed for additional call tags. Returns or warranties will not be issued a call tag.

Labor & Time Lost

BH-USA is not responsible for any labor or time lost by a company due to faulty equipment, incorrect shipments, lost shipments, backorders, or other issues that might be caused by BH-USA or the freight carriers.

Extended Block Worm Assembly

The Extended Block Worm Assembly has a 2-inch bearing block, a worm on a driveshaft, and an aluminum housing with 1/4 inch grease fittings. Attaches directly to the gear plate. The assembly has standard flat-plate mounting holes.

The assembly is fitted with standard flat-plate mounting holes Factory assembled. Blocks are fitted with flange bushings. They have 1/4-inch grease fittings, which can be accessed easily.

The bronze worm is featured on the Standard and Deluxe series flat-plate boat hoists. On the gear plate, the bronze worm turns the 96-tooth cast iron worm gear. When the flat-plate hoist is assembled, the cast iron worm gear turns the drive pipe.

The Advanced series flat-plate boat hoists feature steel worms. The 96-tooth bronze worm gear that is mounted on the gear plate is turned by the steel worm. Once the flat-plate hoist is fully assembled, the bronze worm gear turns the drive pipe.

Worm gears are mounted on the gear plate at the top mounting holes. An assembly block is installed around the middle of the gear plate to match up the gear. When the assembly block’s drive shaft rotates, the worm gear inside the assembly block turns the 96-tooth gear. There is a pulley mounted on the drive shaft of the assembly block, and there is a smaller pulley mounted on the drive shaft of the motor, which is mounted at the bottom of the gear plate. On both pulleys, a belt is installed. The motor rotates its drive shaft in response to the motion of the pulleys on the motor and assembly block, which then turn the worm gear inside the assembly block, which turns the 96 tooth gear. A drive pipe installed through the 96 tooth gear’s bore causes the drive pipe to rotate. If the motor is turning in one direction, or the other, the drive pipe will either raise or lower whatever is attached to it.

There are no mounting fasteners, key stock for the pulley, or pulley included.

Extended Block Worm AssemblyNever use the same material for both worm gears. The use of steel-on-steel or bronze-on-bronze is not recommended for flat-plate hoists. Return policy.
