Dock Building

Types Of Dock Lifts

There are different types of dock lifts, which depend on your location and the type of boat you own. Some key specifications include the lifting capacity, vertical lift travel, and platform width, as well as actuation methods.

Free-standing lifts are great options for shallow waters and can stand alone or connect to shore-mounted docks. Other choices for Dock Lifts Charleston SC include cradle lifts, piling mount lifts, and floating lifts.

A bottom-standing lift is a popular choice for docks that need to be able to accommodate boats of different sizes and weights. It works by anchoring a metal frame to flotation tanks, which are filled with water to sink the drydock and empty of water via a pump to raise it. This allows the lift to operate without stressing the dock or pilings. In this way, it can work in most water depths and can be used with many dock designs.

Another type of dock lift is the floating lift, which uses a system of air-filled plastic or metal chambers. The lift rises when you drive onto it, then sinks again when you are completely positioned in the water. These lifts are great for areas with fluctuating water levels because they can be easily removed or reinstalled as the water level changes.

You can also get a suspended lift that uses two or more forklift-like arms that extend out and support the boat. These lifts can be operated manually or through an electric motor and are ideal for shallow waters with a firm, silty, or powdery bottom. However, they can be difficult to use in high winds because part of the aluminum frame is always underwater and they require frequent maintenance to prevent corrosion.

Finally, you can also get a tunnel lift that has been designed specifically for disabled boaters. This type of lift enables boaters to enter and exit their boats more easily because the gangway is on the dock and the lift moves in and out of the water. This lift also provides protection for the boat from algae growth, corrosion, and damage caused by waves or debris.

Free-Standing Lifts

A free-standing lift system offers the convenience of portable patient lifts and is ideal for temporary lifting needs, rental applications, or for use in homes where ceiling lift track installation is not possible. This freestanding 2-post frame system is designed for use with portable or semi-permanently mounted ceiling lift motors and is easily set up in only 10 minutes without tools. Its height and width are adjustable to accommodate varying floor heights.

Its side pole supports and tracks are constructed of heavy-gauge steel for superior reliability and a maximum weight capacity of 400 pounds. The system legs, “feet” and rail are easy to disassemble for transport and storage.

The Bestcare sit-to-stand lift provides caregivers with a simple, maneuverable, and cost-effective solution for raising weight-bearing patients from sitting to standing positions. This stand-up lift eliminates the need for manual lifting, which reduces caregiver injuries caused by overexertion.

Before using a lift system, the individual receiving assistance must see a medical professional and mobility therapist for a thorough evaluation of their specific needs and proper care instruction. This will help ensure the equipment chosen has an appropriate maximum weight capacity and is sized appropriately for the user. It’s also important that the lift system is used correctly and regularly to prevent overuse.

Suspended Lifts

Working with suspended loads is a daily reality in many industrial environments. It’s important to recognize the hazards and follow strict safety guidelines when handling these loads.

Essentially, anything that’s lifted above the ground is considered a suspended load. These types of loads are typically found on riggings, pallets, and equipment. The larger and heavier the loaded material, the more dangerous it is for workers to work with. Among the risks, there’s always the risk of the load falling due to equipment failure or overloading. In addition, the load may start swinging or shifting during movement, posing a serious threat to anyone in its path.

On construction sites, cranes often suspend large materials, such as steel beams or concrete blocks, to transport them to specific locations for building structures. Warehouses also use forklifts to lift and transport heavy pallets of inventory. In logging operations, fallen trees or heavy machinery are sometimes suspended on cables for transportation to new locations.

One of the most dangerous dangers associated with suspended loads is catching an individual or object between the load and another surface. Injuries from this can be severe, and they’re a major concern in the workplace. Another potential issue is a structural collapse from an overloading or improperly rigged load.

To minimize these risks, workers should have clear communication with each other when performing lifting tasks and follow established emergency procedures if something goes wrong. They should also stay vigilant and focused throughout the operation, and avoid distractions like personal electronics. Finally, it’s crucial to establish a safe zone around the area where lifting operations take place, using barriers or tape to block off the area and keep workers away from the load.

Top-of-Ground Lifts

Top-of-ground lifts are a good option for facilities that have limited space in their bays, as they don’t require any additional space beneath them. They can accommodate a wide range of vehicle sizes, including full-size trucks and low-step vans.

There are two types of top-of-ground dock lifts: symmetrical and asymmetrical. Symmetrical lifts have arms that are directly across from each other, while asymmetrical models feature arms that are offset from one another. This is useful for naturally unbalanced vehicles, as it helps ensure they’re lifted evenly while still giving technicians access to the vehicle’s doors.

Both types are available in a variety of capacities and platform sizes, from 6′ x 6′ to 8′ x 12′. They can also be modified to meet the needs of unusual loads, such as aircraft cargo containers or large artwork for museums.

Depending on the brand, they can be mounted either in-ground or above ground and can either be fixed or adjustable in height. If you choose to mount it in-ground, make sure that the concrete slab on which it is installed can support the load. Otherwise, it will sink during the summer and could present a safety risk.

Above-ground lifts, which are usually mounted on a metal plate that hides the hydraulic mechanisms underneath, can be installed in just a few hours. They’re great for businesses that don’t have the time or money to install a pit-mounted lift, and they can also be moved later if needed without leaving a pit behind for you to fill in.

They can be mounted on a blacktop or a flat concrete slab, though Eagle Equipment recommends using 3,000-psi reinforced concrete for lifts with capacities of up to 10,000 pounds. If you opt for an above-ground lift, it’s a good idea to have the pad leveled by professionals.

Recessed Lifts

A variation on the dock lift, this style features a platform that slides laterally to help bridge gaps between the lift and other surfaces. This is most commonly used to facilitate truck loading and unloading. Other variants include wheels to provide mobility or a ramp to enable the use of pallet jacks (although this requires increased manual force to push them up the ramp) and hand or safety rails for personnel control. These units are usually powered by an external 6.5 HP motor and can be surface or pit-mounted to allow for easier maintenance.

Sized to handle powered equipment such as two-wheel dollies, power pallet jacks, and small fork trucks, these dock lifts offer a wide range of working heights. They typically have capacities up to 20,000 lbs. and platform sizes up to 8′ x 12′.

These are the most popular dock lift styles available because they are simpler to install and afford more crush space beneath the platform than the smaller pits required by other designs. They are also designed for easy accessibility from inside the warehouse where they can be powered and controlled with a remote pendant.

The base frame of a recessed dock lift is designed with a wider stance to minimize deflection. The scissor’s legs are tied together with torsionally rigid torque tubes that add to the overall stability of this type of dock lift. Whether it’s installed on a recessed pit or in the ground, these units can be leveled at any trailer bed height, making them more versatile than dock levelers and safer than ramps and inclines. They are also less expensive than recessed truck wells. They can be used to service any vendor, unlike truck tailgates, which reduce capacity and increase wear on the vehicle, increasing operating costs that are passed to the customer.
