three point fork lift mast?

[Baby Grand]

One thing to be mindful of with those fork lift type 3pt mast set ups:
Check garage opening heights vs mast height when entering or leaving - same goes for low tree limbs.
I mention this after having witnessed someone in a hurry to load a truck, zipping out of the warehouse, lowering a pallet of cedar shakes grabbed from up on a storage rack, but not lowering them quite in fast enough. What a mess.

thanks for the ideas, and links

can someone enlighten me why some have chains+cylinder and some just a cylinder ? What are the pro's <-> cons of both systems ? Safer, stronger, ... ??

Chains allow for a shorter cylinder (moving the cylinder 1" moves the forks 2") which allows for multistage masts and cheaper cylinders (cheaper to use a thicker cylinder than to use a longer one).
Most forklifts have chains, not a direct connection to the cylinder.

Same reason (or opposite I suppose) you have multiple loops of chain/cable on a crane or chain pulley. It basically acts like a gear. Increased movement and speed at the cost of power or decreased movement & speed with more power.

Also not unlike your average extension ladder. It makes it easy to raise a boom really high above the mechanism raising it.

How badly was the mast damaged

Unless it was a heavy metal doorframe, the mast was probably ok, the door frame and the pallet of cedar shakes, probably not so much.

Ok I get it now, thanks for explaining why they use chains guys.
