The gun nicknamed "Long Tom" is a 155mm heavy gun. The gun is so long that if the trunion, which effects the raising and
lowering of the rifle, were put at the center of balance, the breech of the gun would go into
the ground whenever the muzzle was raised high. The solution is to put the trunion farther back, and to make the gun easy to raise and
lower by hand by substituting mechanical balance for natural balance.
It can fire a 95lb projectile upwards of 15 miles with high accuracy.
The equilibrator does the mechanical balancing. |
