The Sky Hook Crane with Mobile Base is the perfect solution for lifting and transporting items off of and onto benches or pallets and is great for general material handling such as pulling out pumps, motors, and other parts. It is ideal for maintenance and service departments and costs less than a forklift or crane—with the added benefit of maneuverability.

It’s easy to take it just about anywhere—even to a job site—because this Sky Hook Crane easily disassembles into sections weighing 34 lbs. or less. The added value of 360° rotation with the ability to straddle the corner of benches, pallets, etc. makes it the perfect portable, manual lifting device for you.

Back injuries and manpower are reduced because it can be used by one person to safely lift and position up to 500 lbs. For specialty applications, custom units of Sky Hook products are also available.

This davit crane comes with either a roller chain or a standard 3/16” cable. Both options are sturdy enough in dealing with heavy duty lifting tasks and provide you with smoother lowering and raising of your load, smoother braking, as well as providing a stronger solution, therefore needing to replace your cables and chains less often. A great advantage when using the Sky Hook Crane with a roller chain is that it also doesn’t stack up like cable on a spool.

The Sky Hook Crane with Mobile Base is available with two different types of braking style which are the friction style brake and the clutch style brake. Please take time in reading our Q & A tab above for the benefits of each one. Both models features an easy to use hook system, allowing you to attach it directly to you load, or to use it with one of our popular add on accessories (see below). We can also customize these units, see detailed images above for details.

Q & A

What is the difference between the chain and cable lifts?

All the Sky Hook models are available in either roller chain or cable configurations.  Each configuration has unique benefits and are best suited for the appropriate lifting application. 

The Steel Roller Chain option provides a consistent travel rate and precise load positioning. Cables on the other hand stack up on the spool, requiring a slightly more amount of force as the cable is reeled in.

Cables are typically quicker and easier to inspect, and many large corporations require cable only for all their lifting devices.

The chain option creates a smoother lowering and raising of your load, smoother braking, as well as providing a stronger solution, therefore needing to replace your cables less often. The cable option is more useful in wet areas where moisture and rust build up is more common.

What is the difference between a friction style brake and a clutch brake?

There are two brake styles offered for the Sky Hook lifting devices. Each brake style offers specific benefits for different applications.

Friction Brake (Economy):

The standard Friction Brake utilizes the friction of a brake on a hub to hold the load applied to the hook of the Sky Hook. This brake style has a lever that protrudes from the top of the Sky Hook gearbox by the hand wheel. Using the Friction Brake is a simple one-hand operation. For the operator to raise the load he must simply rotate the hand wheel clockwise*.

To lower the load, the operator will need to slowly pull back on the brake lever while controlling the rate of descent with the palm of the same hand against the outer ring of the hand wheel. The operator can lower the load as slow, or fast, as desired. If there is a very light load or no load at all on the hook of the Sky Hook, the operator may need to either rotate the hand wheel counter-clockwise*, or pull down on the hook, while pulling back on the brake lever. If at any point the operator lets go of the brake lever, the Sky Hook will hold the load at that position.

The benefits of this brake style can be seen in that it is very economical in that it does not add any cost to the Sky Hook unit. It is also a great option for customers requiring quick operation especially when lowering the load. Customers lowering the load long distances would find it to be beneficial because of the ease of operation.  

Clutch Brake (Premium - Weston Style Brake):

The Clutch Brake option uses the design concept used commonly in handchain operated chain hoists. The Clutch Brake uses mechanical screw forces to hold the load at all times. Releasing the brake is done by the operator rotating the hand wheel counter-clockwise*. There is no lever required to operate this brake. Operation of the Clutch Brake is seamless and convenient.

Raising the load with a Clutch Brake requires the operator to simply rotate the hand wheel clockwise* same as on the Friction Brake. The difference between the two brake styles is in the operation of lowering the load. Lowering the load with a Clutch Brake requires the operator to simply rotate the hand wheel the opposite direction from raising it. The brake does all the work for releasing when necessary.

If at any point the operator lets go of the hand wheel, the Sky Hook will hold the load at that position. The benefits of this brake are in simplicity. It does not require explanation to operate. Employers can trust that the Sky Hook brake will not likely be used incorrectly as the room for error is nearly non-existent. The extra cost of this brake style is easily respected with the additional ease of use it offers.
