This article will guide you through the selection of forklifts, sharing practical tips!
"Forklifts are the most commonly used technical equipment in the warehousing and logistics industry. Do you know how to select the right forklift?" Factors to Consider When Selecting a Forklift
This article will explore the dimensions to consider when selecting a forklift.
The selection of forklift model and configuration generally considers the forklift's operational functions, operational requirements, and operating environment, such as warehouse size, ground conditions, and aisle width. A comprehensive analysis of these factors can determine the required forklift type, tonnage, and configuration.
The following are factors to consider when selecting a forklift:
1. Operating Environment
Indoor vs. Outdoor: For indoor use, electric forklifts are recommended to reduce emissions and noise; outdoor environments typically require powerful diesel forklifts.
Aisle Width: Narrow aisle warehouses require narrow aisle forklifts (VNA) or reach trucks to accommodate limited operating space.
2. Cargo Type and Characteristics
Cargo Weight: Overweight cargo requires forklifts with high load capacity while ensuring load stability.
Cargo Size and Shape: Extra-long or irregularly shaped cargo may require side forks or special attachments.
Storage Method: Stacking height and rack design directly affect lifting height requirements.
3. Climate Conditions
Low Temperature Environment: For cold storage, forklifts with low-temperature protection should be selected, such as using low-temperature resistant batteries and lubricants.
High Temperature Environment: Forklifts with strong heat dissipation capabilities are recommended to avoid overheating.
Humid Environment: Forklifts with corrosion-resistant designs should be selected to extend equipment life.
4. Special Industry Requirements
Food and Pharmaceutical Industries: Forklifts must meet strict cleanliness and hygiene standards; electric or stainless steel forklifts are recommended.
Hazardous Goods Transportation: Must meet safety standards and be equipped with explosion-proof devices.
Forklift Equipment Introduction
01 Forklift Selection Principles
When selecting a specific forklift, we need to refer to the following parameters to make selection recommendations:
(1) Forklift Tonnage Configuration. Different cargo weights and maximum fork heights determine the forklift's load capacity. As the fork height increases, the safe load capacity of the forklift gradually decreases. For example, a 2T electric forklift can carry 2T of goods when operating at a low position, but when it is lifted to a height of nearly 5 meters, its safe load capacity may only be 800KG or at most 1000KG. Exceeding this weight may be dangerous.
(2) Forklift drive. Both electric and diesel forklifts are needed; due to the involvement of indoor and outdoor operations, the ratio of these two configurations must be considered.
(3) Forklift lifting height. The appropriate lifting height should be selected based on the warehouse's high-bay operation requirements and warehouse height. Generally, combining low-level and high-level operations can reduce the total procurement cost.
Forklift lifting heights from standard configurations of 3 meters, 4 meters, 5 meters, 6 meters, 7 meters, and 10 meters+ should be appropriately considered.
(4) Forklift mast height. Considering that the forklift needs to enter the container for operation, the mast height must meet the requirement of a net height of less than 2.3 meters inside the container, requiring at least two mast sections. However, it should be noted that the lifting height and mast height may conflict and need to be balanced. (5) Side shifter configuration. To improve the accuracy and flexibility of forklift operation, it is recommended to configure side shifters.
(6) Tire quantity selection: Choose a three-wheeled or four-wheeled forklift based on the width of the operating aisle. Three-wheeled forklifts have a smaller turning radius.
(7) Maintenance cost. Maintenance cost is also an important factor to consider. For battery-powered forklifts, choose between DC and AC motors, and further distinguish between fully AC and partially AC, as this will directly affect subsequent maintenance costs.
(8) Minimum turning radius. When the forklift is traveling at low speed without load and turning with the steering wheel fully turned, the minimum distance from the outermost and innermost sides of the forklift body to the turning center is called the minimum outer turning radius and minimum inner turning radius, respectively. The smaller the minimum outer turning radius, the smaller the ground area required for the forklift to turn, and the better its maneuverability.
(9) Considering the width of the forklift operating aisle. If it is not possible to purchase a high-cost forklift, it is also necessary to consider whether to choose a three-wheeled or four-wheeled forklift. Three-wheeled forklifts have a much smaller turning radius. 02 Introduction to Various Types of Forklifts
Warehouse forklifts are primarily designed for handling goods within warehouses. During multi-shift operations, motor-driven warehouse forklifts require spare batteries.
(1) Electric Pallet Truck: Load capacity ranges from 1.6 to 3.0 tons. The aisle width is generally 2.3 to 2.8 meters, and the fork lifting height is generally around 21 cm. It is mainly used for horizontal handling and loading/unloading goods within warehouses. Generally, there are two operating modes: walk-on and stand-on, which can be selected according to efficiency requirements.
(2) Reach Truck: Load capacity ranges from 1.0 to 2.5 tons. The mast can be moved forward or retracted as a whole. When retracted, the aisle width is generally 2.7 to 3.2 meters, and the maximum lifting height can reach approximately 11 meters. It is commonly used for medium-height stacking and picking operations within warehouses. (3) Stacker With a load capacity ranging from 1 to 1.6 tons, the operating aisle width is generally 2.3 to 2.8 meters, and the fork lifting height is generally within 4.8 meters. It is mainly used for stacking and unloading goods in warehouses.
Stackers are simple in structure, flexible in operation, have good micro-motion capability, and high explosion-proof safety performance. They are suitable for operations in narrow aisles and confined spaces, making them ideal equipment for palletized loading and unloading in elevated warehouses and workshops.
They are widely used in industries such as petroleum, chemical, pharmaceutical, textile, military, paint, pigment, and coal, as well as in places containing explosive mixtures such as ports, railways, freight yards, and warehouses for loading, unloading, stacking, and handling operations. They can greatly improve work efficiency and reduce the labor intensity of workers. Stacker - Classification
1. Manual hydraulic stacker (without any power unit, relying entirely on manual pushing and pulling for lifting, small turning radius, and laborious lifting)
2. Semi-electric stacker (using hydraulic devices, electrical control components, and a lifting mast, manually pushed and pulled for forward and backward turning, electrically lifted, small turning radius, flexible and convenient)
3. Fully electric stacker (self-propelled electric lifting, convenient and fast to use)
Stacker - Main Features:
1. High stability.
2. Low noise, no pollution, and low failure rate.
3. Front and rear movement of the mast, small turning radius.
4. High lifting height, suitable for high-rise stacking.
(4) Counterbalance forklifts
1) Electric forklifts. Powered by an electric motor and powered by batteries, with a load capacity of 1.0~4.8 tons and an operating aisle width of 3.5~5.0 meters, used for indoor operation and other occasions with high environmental requirements.
2) Ordinary internal combustion forklifts. Generally powered by diesel, gasoline, LPG, or natural gas engines, with a load capacity of 1.2 to 80 tons and an operating aisle width of 3.5 to 5.0 meters, these forklifts are commonly used outdoors, in workshops, or other locations where exhaust emissions and noise levels are not critical.
(5) Three-way stacker forklifts
These are available in high-level and low-level driving configurations. The forklifts do not require steering to stack and retrieve goods from both sides. The aisle width is 1.5 to 2 meters, and the lifting height is approximately 12 to 14.5 meters. Unmanned driving solutions can achieve even higher lifting heights.
Features of narrow aisle three-way forklifts: Narrow aisle three-way forklifts are a special type of forklift that can operate in narrow aisles. Their main features include:
1. Both the main and auxiliary wheels can rotate freely 360 degrees, effectively handling confined operating spaces.
2. They can travel in both directions within narrow aisles, improving the efficiency of goods handling.
3. They can store and retrieve goods on higher shelves, maximizing warehouse space utilization. Common applications include: Currently, it is widely used in industries such as machinery manufacturing, chemicals, and pharmaceuticals, as well as in supermarkets, cold storage facilities, and other locations for loading, unloading, storage, handling, and stacking operations.
04. The Combined Use of Forklifts and Shelving
How to select and match shelving and forklifts to minimize collisions?
1. When planning a warehouse, you can request the racking manufacturer to appropriately increase the width of the drive-in racking aisles to allow for safer distances for drivers, thus reducing forklift collisions with cantilever arms.
2. Adding protective covers to cantilever arms or guardrails can reduce forklift damage to the racking, but this method can provide opportunities for less skilled drivers, making it difficult for managers to assess driver skill levels.
3. Painting visual deceleration lines on the aisle floor instead of speed bumps can be ineffective. Experienced drivers often drive at high speeds, leading to discrepancies between visual perception and actual speed, so simple speed bumps may not be very effective.
4. Installing fork sleeves on forklifts can effectively reduce damage to pallet edges and corners. However, the feasibility of this method should ideally be verified through safety testing by the forklift manufacturer.
In practice, forklift selection must be based on a comprehensive consideration of production scale, workload, operational processes, and warehouse conditions. Have you grasped these key points regarding forklift selection?
