Forklift types that commonly utilize counterweights are the stand-up rider and sit-down counter-balanced forklifts. … Counterweights are used to secure a proper weight distribution and maintain stability, to prevent the vehicle from tipping over and to ensure the safety performance of the vehicle.
What is a forklift counterweight made of?
The manufacturers prefer using either full cast iron, full concrete, or a mix of concrete and metal bits. For example forklift counterweights are commonly made of metals for maximum space utilization.
What is the purpose of a counterweight?
A counterweight is the stabilizing part of a balancing system for a lifting mechanism or machine. They are used in lift trucks, draw bridges, elevators, cranes, and any machine that lifts a lot of weight.
Where is the counterweight located on a forklift?
Internal combustion forklift counterweights are located toward the back of the forklift, or on the opposite side of the forks.
What acts as the counterweight on an electric counterbalanced forklift?
In an electric counterbalance forklift, the battery often forms the counterweight. Counterbalance forklifts can be found in practically every manufacturer’s product range. They are manufactured in a variety of sizes and configurations, and use a range of fuel sources.
What are the three major parts of a forklift?
The three major parts of a lift truck are the body (truck), overhead guard, and hydraulic lift.
How much can a 5000 lb forklift lift?
A 5,000-lb. capacity forklift will lift that much weight up to 48-inch forks (with a 24-inch load center) but going out to 60 inches (with a 30-inch load center), for example, drops the capacity to 4,000 pounds.
How does a counterweight system work?
A counterweight is a weight that, by applying an opposite force, provides balance and stability of a mechanical system. The purpose of a counterweight is to make lifting the load faster and more efficient, which saves energy and is less taxing on the lifting machine. … The objects are then said to be in counterbalance.
How do you calculate counterweight?
Suspended access equipment—Counterweights
The load required by the counterweights is determined by dividing the resisting force by the distance on the beam from the centre of counterweights to the fulcrum (L).
How much weight do I need to counterbalance?
Using the equation, _Fe × de = Fl × dl, the torque for the weight, or effort force, is then 2,000 pounds times 50 feet, or 100,000 pound-feet for the weight. The counterbalance weight, or load force, is then, 100,000 pound-feet divided by 20 feet, or 5,000 pounds.
Which side of the forklift is supporting more weight?
Weight distribution refers not only to the weight of the load, but also the weight of the forklift itself. An empty forklift has most of its weight in the rear, but when a load is placed on the lift, the weight distribution moves forward.
What are the 3 levers on a forklift?
A forklift’s directional controls help move the lift forward and backward. There are three forklift directional controls: park, drive, and reverse. Directional controls can be mounted to a lift’s steering column. Or, they may be placed in a position where an operator controls them with their foot.
Can a forklift tip-over without a load?
Can a Forklift Tip-Over Without a Load? A forklift can become unstable, even if it does not have a load. For example, if a driver turns too fast around a sharp curve, their lift can tip. Or, if a driver is traveling on an unbalanced surface, their lift can tip if it shifts too far in one direction.
What do the 4 levers on a forklift do?
One that lifts the forks up or down, the second one tilts the forks/blades down or up to secure the load, and the third to move the load side to side. Some types of forklifts have a knob that controls the width of the fork.
When picking up a load the forks should be spaced?
The forks should be at least two-thirds the length of the load. The mast must be carefully tilted backward to stabilize the load. Ensure the load is secured before moving. Slowly move the truck to 20 to 30 cm (8 to 12 inches) away from the stack.
What is the load backrest connected to?
Load backrests play an important role in keeping your drivers safe. They prevent your forklift’s load from falling toward the driver. It features a steel grid above the forks and attaches to the sides of the forklift carriage with heavy-duty, steel framing.
