Pin Type Forks, Special Mounting & Shapes
Pin Type Forks, Special Mounting & Shapes
Forklifts with over 15K lbs Capacity, Telehandlers, Wheel Loaders
All our forks are forged, shot-blasted, machined back, sides and tapers and are guaranteed to be level at the tips within ISO standards. All Fork-Co ITA/ FEM class Forks are high yield heat treated alloy steel, ASTM 4140 or 4340. Our larger pin-type (tube) forks are 15B37 very high yield steel. All our forks undergo individual magnetic powder crack checking.
Forks can be manufactured to your specific needs and dimensions.
Fork-Co can help you identify the correct fork for your application.
We welcome your calls and questions. Our pin type forks are manufactured in Alvin, Tx and we can customize and supply all types of specialty forks.
Pin and Special Fork Types
Pin type Forks:
Pin type forks have no standard shape or size. They vary from OEM to OEM and by trucks within a brand. Because of this we ask many questions of customers. We use 2 drawings to gain dimensional data needed to make the forks to fit. These tell us where the fork tubes are located. The most important dimension is the location of the tube center in relation to the rear face of the fork shank. This dimension tells us the “offset” or “inset” of the tube, or whether it is “in-line.”
In relation to the rear face of the fork shank, offset means the tube center is located toward the driver. Inset means the tube center is located toward the load. In line means the center is directly above the rear face.
Type of forklift that is mounted on the rear of trailers and is carried to building sites to unload the flatbed. These are called “piggy-back” forklifts.
Block or Brick Forks:
Block Forks are narrow forks, usually used in multiples, that enter the openings of concrete blocks that are turned on their sides. A layer of these blocks is used as the actual load carrying pallet in unit loads of blocks.
Lumber or Plywood Forks:
Lumber Forks or Full-Tapered Forks or Full-Taper and Polished Forks are made with a typical maximum thickness of 1.5 inches and in various widths, depending on the load weight. They are all made as full bottom taper forks, meaning the taper runs from the tip , back to approx. 2 inches from the bend. The top of the blade is polished, unpainted, for ease of entry and exit. Tips are thin with a top chamfer for chiseling between plywood sheets and the tips are squared off, not rounded, to assist the chiseling effort.
When these forks become very wide, they can block the driver’s visibility. Therefore, a “peek-a-boo” fork is used. This fork has a shank that is thicker than the blade. At a certain distance above ground level the shank narrows to allow the driver better visibility.
Gypsum Forks are forks having a tall shank that extends very high above the top hook. To this shank, a synthetic covering, usually replaceable, is added.
Coil Forks are used to handle steel or other coiled materials. These forks made with the top corners of the blades chamfered or radiused to prevent scoring or denting of the inner layers. When both forks are used together in the core, only the top outer corners need this shape. If each fork is used to handle one coil each, then both top corners of the fork are chamfered.
Kiss Forks are used to handle coils and are made with a bend in the lower shank. The bend shapes the fork shank so that even though the shanks are separated, they offset toward each other so that the blades “kiss” each other. The forks are then used in the core of the coil. The reason for this offset is that the center vertical support bar of the pin type carriage on which they are used does not allow the forks to touch. The standard width from outside to outside of the forks when fully closed down may be too wide for the core.
Tire Forks are forks having a full length bevel along the inner face of the fork. This bevel is used to allow the forks to slide under the tread of a tire or stack of tires for damage prevention and stability during handling. Tire forks have a blunt tip and no bottom taper.
Folding Forks fold up against the shank. They are used to shorten the overall length of a forklift. Uses could be in space restricted areas like elevators, or on forklifts that are transported on the platforms built onto the rear of flatbed trailers. Minimum thickness of these forks is 2 inches and they are mostly in class II or III hook configurations.
Spark Retardant Forks:
Spark retardant forks are used in hazardous operations where spark-proof forklifts are used or where sparks may caused combustion/explosion. These forks are brass coated both on the blade and the face and sides of the shank. The brass is usually 1/8” thick and perhaps a little thicker on the bottom for wear resistance. The brass cladding is a weldment made to fit tightly onto the fork. It is not removable. Stainless steel cladding can be used for applications where sanitary requirements are prevalent: Pharmaceutical, Beverage, food processing, where the fork is exposed to the product in the manufacturing process.
Drum forks are forks having the inside of the blade radiused to match the wall of a standard steel 55 gallon drum. This design is used on fork positioners and pallet fork clamps. These cut-out forks can be configured as one cut-out on each fork to handle single drums or two drums side by side, or two cut-outs per fork to handle two drums or four drums. The thickness of these forks should be increased due to a loss of capacity caused by the radius cuts.
