How to Operate a Forklift
Driving this type of forklift differs from driving a car in that the movement is carried out by the rear wheels.
There are several rules for driving a forklift vehicle:
- It is prohibited to carry passengers in the cabin.
- Before starting work, you must ensure that the locking batteries, fuel tanks and their caps are securely fastened.
- During the execution of the task, the unit's load-carrying capacity restrictions must be observed.
- The forks should be positioned as far below the load as possible. The fork spacing must be correct to ensure load support.
- You cannot transport goods that are poorly folded or packaged.
- If visibility is lost due to the load, then you need to move in reverse.
- It is forbidden to make sharp turns and stops; movement must be smooth.
- It is necessary to monitor the position of the wheels in relation to the edges of loading ramps, platforms and other vehicles.
- It is recommended to mark the work area with yellow lines.
- Before parking, you must move the control levers to the neutral position.
- It is prohibited to lift people on the forks of the forklift.
Selection criteria: what to look for when choosing
From our review you will learn what a forklift is and what types there are, and we will also consider in detail the following characteristics, knowledge of which affects the correct choice:
- engine types;
- load capacity;
- lift height;
- building height;
- fork size;
- number of wheels;
- tire type;
- transmission type;
- counterweight;
- optional equipment;
- safety;
- price.
Basic faults, maintenance and repairs
Operators may encounter the following forklift problems:
- Breakdown of the working mechanism.
- Engine or transmission failure.
- Malfunctions of the brake, hydraulic or steering systems.
In order to avoid breakdowns, it is necessary to carry out scheduled maintenance of the unit in accordance with the operating manual.
Repair of forklifts can be carried out as follows:
- If the working mechanism fails, you need to inspect it, lubricate the bearings, check the condition of the tension chains, the movable frame booms and the integrity of all links.
- If the engine or transmission fails, it is necessary to replace the fuel filters and check the oil level. Do not allow the oil fluid to overheat.
- If the breakdown is in the brake or steering system, you should check the brake fluid level and make sure that there is no leak in the brake master cylinder. The steering rack needs to be inspected.
Mast replacement
Practice shows that when buying a forklift, customers try to save money and buy forklifts and electric forklifts with a standard mast, since it is cheaper.
Then they move to another warehouse, where the racks are already one tier higher. So what should I do? Buy a new forklift? But the existing one is satisfactory, except for the lifting height. Change the mast? But who will help? "Sklad.ru" replaces the mast or replaces the loader in its own Service Center. Send a request or call 8-800-250-83-33
Terms of use
To ensure reliable and uninterrupted operation, reduce depreciation and increase the service life of components and components when operating forklifts, it is important to follow certain rules and regulations.
For example, the Operating Instructions for a forklift require mandatory compliance with the following points:
- 1.Operator qualifications.
Skilled worker
Loading and unloading operations must be carried out by an employee who has the appropriate skills and has been trained to operate this type of equipment.
- 2.Use of special work clothes.
It must have protective properties. The operator's kit must include: a helmet, safety shoes and a jacket with reflective elements. When working, clothing should not cling to the elements and parts of the loader.
- 3.Preliminary inspection.
Before loading and unloading operations begin, the operator must inspect the vehicle to identify possible problems and malfunctions. If they are detected, the loader cannot be allowed to operate.
- 4.Launch.
Access to the cabin is via steps supported by handrails.
The operator must be fastened in it .
Work can only begin in a seated position, unlike crawler loaders.
Load capacity
This is the first thing to think about. At first glance, it may seem that there is nothing complicated in this issue, and to make a final decision regarding the forklift model, it is enough to read the technical documentation. In practice, everything is more complicated. If only for the reason that lifting capacity can be nominal and residual: nominal lifting capacity is the maximum permissible weight of cargo that a forklift can lift. Residual lifting capacity is the weight of a load that can be lifted to a certain height without losing the stability of the forklift. More lifting height means less residual load capacity. The higher the lifting capacity of a forklift, the more expensive it is. Therefore, try to determine as clearly as possible the operating parameters of warehouse equipment and the cargo being processed before purchasing.
Engine
The main element of any machine, the right choice guarantees trouble-free operation of the equipment and saves the budget from unplanned expenses.
First, you should clearly determine where the loader will be used. If we are talking about working only indoors, the best solution would be an electric motor (especially if the work involves loading such categories of goods as food, medicines, etc.).
Electric forklifts are economical to operate and maintain and are highly reliable. The standard acid battery of an electric forklift is designed for continuous operation within 5-7 hours; if this operating time per shift is not enough, then it is necessary to purchase an additional battery. It should be remembered that to charge acid traction batteries you will need a specially equipped charging room with ventilation.
The diesel engine, on the contrary, is designed for operation on the street or under a canopy; it has the longest service life, is unpretentious in operation, and economical, but, unfortunately, its exhaust gases are toxic and dangerous for personnel when working in a confined space.
A gasoline engine will be an intermediate option; it makes sense to immediately equip it with gas equipment, which will make it possible to work both in a warehouse (with good ventilation) and on the street. This engine option will be cheaper than an electric one and will not create the need to equip a warehouse with a charging room, which is important for small enterprises.
The next important question regarding the choice of internal combustion engine will be the manufacturer. How not to make a mistake and not overpay? Let's explain. If the forklift will be used in a standard eight-hour shift or less, then you can safely save money and opt for a diesel engine version from a Chinese manufacturer, for example Xinchai 485, 490, Weichai WP4.1 and LuoTuo LR4B3. They are reliable, have good power and will more than return the money invested. For enterprises with a round-the-clock operation cycle, we recommend purchasing configurations with Japanese engines Isuzu C490, Mitsubishi S4S, S6S. With long operating hours, the Japanese engine shows itself to be more efficient and cheaper to operate due to its longer time between failures. Definitely choose a gasoline loader with a Japanese internal combustion engine (Nissan, Kubota, etc.), the quality of gasoline engines from Chinese manufacturers leaves much to be desired.
A few words about attachments
The forklift comes standard with forks. But to get a truly functional lifting and transport machine, this is not enough. We recommend that you think in advance about equipping your equipment with attachments and consult regarding their compatibility.
All attachments are divided into 3 large groups:
- devices to improve the convenience of working with forks (for example, side shifters and positioners);
- devices that expand the capabilities of equipment (load pushers, fork extensions and tippers, clamping parts, carriage rotation mechanisms);
- mechanisms for solving new problems (mechanical grippers for bales, barrels and paper rolls, buckets for bulk materials, mandrels, etc.).
Before connecting the attachments, you need to expand the capabilities of the hydraulic distributor, separate the hoses, and perform other manipulations. Next, it is important to make sure that the new devices work correctly.
