The Challenge riggers face in the field is the delivery of unrated crane bins. Items show up on a truck and they rig it up with straps to get it off of the truck. If you don't fly overhead, most jobs wouldn't think much of it. If you are with a large contractor with any sophistication, they'll want that box rated. It's required in OSHA 1926.251 and ASME B30.20. 

Subcontractors and suppliers make life difficult with bins that solve their issues without considering the legal requirements to attach them to a crane. What we can do is supply bins that either take care of this at the supplier level, or you can transfer them on a job site. 

We have Pallet Bins that are designed to be the size of a pallet at 40 by 48 inches. They can be singles or doubles. Rated at 3300 or 6600 lbs respectively. You can get them with gates like these, or a drop down ramp so you can land it on a roof then pallet jack the items out. You have a 4 point lifting system at the top so it can't get out of level. These would typically have a shackle at the top so you can just hook in. If you wanted to use it with a forklift, it has the pockets integrated for that. 

We have Pall Skips that come up to 7' long by 4'-9"  and 2.5 tall. The result is that it's a 2 yard bin rated at 6600 lbs on a four point lift. Toss in that random rebar that is sharp and hard to rig up. Those rolls of roofing or shoring waterproofing. Really, just anything random can go in these and be safety transported. Stop thinking the box will be ok and feel the certainty the Pall Skip can deliver. When you get to the location, if you wanted to dump out the items, the front is sloped to make this easy if you simply remove the two front connections and hoist up just on the back two lifting loops. 

Universal skips are set up to work with both cranes and forklifts. The stack together for easy storage and shipping. They vary in size from 0.39 yards to 1.3 yards. At 1.3 yards, think of them as similar to a pallet sized bin. It's a good option to replace plastic tote bins that are set up by subcontractors on castors. These are simply rated and won't fail at an undetermined time because they aren't plastic. 

These are the size of a pallet at 47 by 41 inches. Most pallets won't fit in them, but essentially the same items will. Coming with castors optional, if you are looking for pallets or pallet totes to solve your needs in transporting gear, this is a solid offering to get in compliance. In doing so, you'll be faster and safer at the same time. 

On the market you'll find Bulk Bins. These are stackable, add castors, lids, powder coated, galvanized, dumps out on the rear lifting eyes. And they range from 0.39 yards to 5.3 yards and have a rating of 13,230 lbs. Four point lifting as a stack of two as well. These are an awesome utility. When set up to 1 yard as the size, you can access materials in the top or bottom bin. You could replace stillage bins quickly with these.

In Europe these are used to collect waste. Much of their construction is brick based. So you'll see these getting abused with people throwing bricks at them for decades. And they take it. The durability for our operations in the US would be incredible. They'll last careers. 

Drop Bottom bins are another incredibly durable bin that is for cranes, forklifts, Castors, they can be done in two compartments, with mesh instead of 3 mm plate. Rated at 4400 lbs and up to 2.6 yards, these can be trash bins, move supplies, or materials. Put castors on them and push them around a floor. Then take them to the hoist where they can be brought down and dumped out with the forklift. Or if you need to scrap out a floor with a crane, little gets in the way of loading it. When you get to the dumpster you can drop the bottom either quickly if it's light (think of the shockloading) or set it in the dumpster, pull the rope and hoist up so it gently comes out. This is another item that will last a career. 

Square stillage with Eichinger is rated up to 4400 lbs for crane lifts. 

They come as bins as well. 

The round variant can have links as the lifting points and be rated to 3300 lbs. 

They also come in mesh or steel sides. 

Beyond the safety of having lifting eyes versus slings, if you spend 20 minutes a day looking for slings, rigging them up, and inspecting, and let's say the sub contractors lose 2 hours a day in pre-rigging items, that miniscule number leads to an $84,000 loss of income for the job. 20 minutes on a 5 day work week. We are expensive as labor. Eichinger and Seattle Tower Crane can help mitigate these expenses simply by supplying four point lifting eyes on all of our bins. The question is, do you spend up front to save multiples on the back end? I would suggest it as a good idea.
