What a 5 Ton Chain Hoist's Chain Size and Net Weight Really Mean

How thick is the hand pull chain on a 5-ton chain hoist, and how much does the unit weigh? On the Harrington CB050 — the 5-ton model in the CB series, and the only unit this article covers — the chain figure is a load chain diameter paired with a chain fall count, and the weight question splits into net and shipping, two numbers that never substitute for each other. The pound figure sitting in that same row is pull-to-lift effort: how hard a person pulls on the hand chain, not how thick any chain is.

That confusion is the reason buyers carry the wrong number into a beam check, a quotation or a receiving count. Nothing on the row is hidden. The columns simply answer different questions, and the labels are terse enough that a pound sign gets read as a size.

Which Chain Does 'Chain Size' Describe?

A manual chain hoist runs two chains, and they do different jobs. The endless hand chain loops down from the hoist body and is what the operator pulls. The load chain runs from the hoist body down to the bottom hook and carries the load. The spec sheet describes the second one: its column heading reads Load Chain Diameter in millimeters times chain fall lines, so the honest answer to that phrase is two-part — a diameter, plus how many strands run between the hoist and the hook block.

There is no hand-chain diameter column on that sheet at all, and that is not an oversight. The hand chain is not a dimension a buyer selects; it comes as part of the hoist assembly, matched to the gearing inside, so the row has nothing for a buyer to spec there.

The number that gets mistaken for chain size is pull to lift load, in pounds. The reason it draws the eye is that it is the largest figure in the row and the only one a person feels directly — it is the effort at the hand chain, and it tells you whether one operator can make the lift or whether the lift takes two.

Why a 5 Ton Hoist Runs More Than One Fall

Start from the constraint. A manual hoist is powered by an arm, so the whole machine is built around how hard a person can pull. Because the pull at the hand chain is capped by the operator, the hoist trades hand travel for load travel: the operator pulls a long way to move the load a short way.

The reeving does the rest. In a multi-fall arrangement the load hangs on more than one chain leg, so each leg carries a fraction of the total tension, which means no single strand has to be sized for the full rated load. Chain diameter stays manageable, hand effort stays inside what a person can produce, and the cost is speed — a multi-fall hoist lifts slowly.

The manual puts the 3 Ton (CB030) through the 20 Ton (CB200) units in one group it calls multiple chain fall hoists, and a 5-ton unit sits inside that range. That is why its row shows a fall count beside the diameter instead of a bare diameter; the fall count is part of the machine, not an option. It also means the count is not a multiplier you apply yourself, because rated capacity belongs to the complete reeving as built.

Net Weight and Shipping Weight Do Different Jobs

The spec row carries three weight columns, not one: net weight, approximate shipping weight, and weight for each additional foot of lift. They answer three different questions, and mixing them is the most common way a 5-ton purchase goes wrong before the hoist is unboxed.

Size the beam and the trolley on net weight, and on nothing else. The reason is that packaging rides the truck to your dock and then goes into the dumpster — mass that never hangs from your structure has no place in a beam, jib or trolley calculation.

For the receiving count, flip it: shipping weight is the column that matters, because that is what lands on the pallet. A clerk who counts against net weight flags a complete shipment as short every single time, since the gap between the two columns is the packaging.

The third column is the one people skip and later regret. Each additional foot of lift adds its own increment of mass, which means a hoist built to a longer lift is a heavier installed unit. A weight figure is therefore meaningless until you know what standard lift it was quoted at, and anyone planning overhead support needs net weight at the lift length they are actually buying.

What the Manual Checks Before the First Lift

Before the first operation the manual requires two checks on the chain and hook: verify the load chain is not twisted or tangled, and make sure the bottom hook on the multiple chain fall models — 3 Ton (CB030) through 20 Ton (CB200) — is not capsized. Both failure pictures in that section, twist in the load chain and a capsized hook with its chain, are drawn on the double-fall version of the hoist.

The reason those checks sit beside a chain-size question is structural. A multi-fall reeving puts more than one strand in the same space, so a strand can roll over its neighbour, and the hook block can come up flipped while still looking assembled. A single strand has nowhere to go wrong that way. The manual also requires all chain irregularities to be corrected before the first hoist operation, which means the check happens before the load goes on, not after the first lift looks odd.

The hard rule on length belongs here too: never lengthen the chain by attaching additional links to it or by any other means. That is a prohibition, not a preference, and it applies to the chain that carries the load.

Why You Order Chain Length, Not Extra Links

If a job needs more height than the standard lift provides, the answer is a longer chain ordered with the hoist. Any lift of chain is available on request, and the buyer specifies the length desired when ordering. Harrington states that its chains are specially heat treated and that only authentic Harrington chain should be used on the hoist, which is why this chain is not a commodity you match by diameter at a supply house.

Ordering length instead of splicing has a weight consequence. Because the spec row prices extra height as a per-foot weight increment, a taller lift is a heavier hoist, and the beam or trolley carrying it sees that added mass.

Suppose a warehouse plans a 5-ton pick from a mezzanine rail where the hook has to reach further than the catalog lift allows. Model the longer lift and its added chain mass at the quotation stage, while the beam is still being sized and the chain is still being made to length, because on site the remaining options are all wrong ones. Note which dimension you are changing, too: load chain length moves the hook, while the hand chain loop hangs at the hoist body, so extra lift height does not put the pull any closer to a standing operator.

Fields to Confirm on the CB050 Spec Row

Match the capacity to the product code, not to the capacity alone. CB050 is the 5-ton unit, and the row is what identifies it; a quote that says 5 ton with no model code cannot be checked against anything.

Read the chain column the way it is written, never as a single number, a link pitch or a hand-chain size. Keep net weight and shipping weight in separate cells with the per-foot lift increment beside them, and record the standard lift the weight was quoted at, because the figure only holds at that lift. Confirm the chain is the original maker's heat-treated stock, since that is the one substitution the manual rules out.

Then check the page itself rather than a copy. A spec table pasted into a spreadsheet or a text file can lose the relationship between a merged cell and its column heading, and a figure that has drifted one column to the left still looks like a figure. The deliverable that holds up is a checked row with the model code, the column name and the lift length attached.

That is the trade. Reading the row this way costs you the one headline number you could have fired off in a reply, and it costs a few minutes with the PDF open. What it buys is a chain size and a weight you can defend when someone asks which column they came from, which is what the beam, the trolley and the receiving clerk actually need.
