2. Which brand of truck-mounted crane is good?
Selecting aထရပ်ကားတပ်ဆင်ထားသောကရိန်းisn’t simply a matter of determining which brand is superior. Aထရပ်ကားတပ်ဆင်ထားသောကရိန်းis a modified vehicle and is composed of three main parts: the chassis of the vehicle, the crane itself, and the cargo box.
(1) The chassis of the vehicle can be sourced from manufacturers like Dongfeng, FAW, ဓာတ်ပုံများ, Sinotruk, etc.
(2) Popular crane machine brands include XCMG crane machine, Shimei crane machine, Dahan crane machine, နှင့် ပို.
(3) The cargo box is typically modified by enterprises with the necessary modification qualifications. The choice of a goodထရပ်ကားတပ်ဆင်ထားသောကရိန်းinvolves considering the quality and reputation of each component manufacturer, as well as the overall integration and performance of the assembled vehicle.
3. What certificates are required for the driver of a truck-mounted crane?
The driver of aထရပ်ကားတပ်ဆင်ထားသောကရိန်းis obligated to possess three essential certificates: a Class B driver’s license, an operation certificate for getting on the vehicle, and a professional qualification certificate. The driver’s license is commonly referred to as the off-vehicle certificate, while the operation certificate is known as the on-vehicle certificate. These certificates ensure that the driver is qualified and legally authorized to operate the ထရပ်ကားတပ်ဆင်ထားသောကရိန်းsafely and in compliance with the law.
4. How long can the carriage of a truck-mounted crane be?
The carriage length of aထရပ်ကားတပ်ဆင်ထားသောကရိန်းvaries depending on its capacity. 2-ton crane machines are usually installed on relatively small vehicle chassis, such as those produced by Dongfeng, including the Dongfeng Xiaobawangထရပ်ကားတပ်ဆင်ထားသောကရိန်းchassis and the Dongfeng Jinba truck-mounted crane chassis. The carriage size of 3-ton, 4-ton, and 5-tonထရပ်ကားတပ်ဆင်ထားသောကရိန်းs generally ranges from 3 ရန် 6 မီတာ. The length of the carriage for 5-ton, 6-ton, 8-ton truck-mounted cranes can typically be 5.8 ရန် 6.1 မီတာ. For 8-ton, 10-ton, 12-ton, and 16-tonထရပ်ကားတပ်ဆင်ထားသောကရိန်း၎, the carriage length can extend to 7.5 – 8.5 မီတာ. It’s crucial to select the appropriate carriage length based on the specific tasks and payload requirements to ensure efficient and safe operation.
5. Are there any differences between a truck-mounted crane and a vehicle-mounted crane?
Yes, there are distinct differences. Aထရပ်ကားတပ်ဆင်ထားသောကရိန်း, also known as aထရပ်ကားတပ်ဆင်ထားသောကရိန်းtransport vehicle, represents a seamless combination of a freight vehicle and a crane. It enables both lifting and transportation in a single operation. မတူတာကတော့, a vehicle-mounted crane refers to a lifting platform installed on an automotive platform but lacks the capability to carry goods. Its sole function is lifting and it is not designed for the transportation of goods.
6. Are there currently dump-type truck-mounted cranes?
Typically, standardထရပ်ကားတပ်ဆင်ထားသောကရိန်းs come equipped with regular cargo boxes and do not inherently possess the dump function. သို့သော်, upon customization by the manufacturer ofထရပ်ကားတပ်ဆင်ထားသောကရိန်း၎, the dump feature can be incorporated. Naturally, in such cases, the strength of the cargo box also needs to be concurrently enhanced to withstand the additional stress and functionality.
7. In an 8-ton truck-mounted crane, does the “8 တန်” refer to the maximum lifting weight of 8 tons or the limited load of 8 တန်?
In an 8-tonထရပ်ကားတပ်ဆင်ထားသောကရိန်း, အဆိုပါ “8 တန်” indicates the maximum lifting weight it can handle.
8. What can a 3-ton truck-mounted crane haul?
A 3-tonထရပ်ကားတပ်ဆင်ထားသောကရိန်းfinds applications in landscaping, small-scale construction sites, power companies, and similar settings. A 3-ton ထရပ်ကားတပ်ဆင်ထားသောကရိန်းoften features a powerful card blue-plate truck-mounted crane and can be equipped with a 2-ton or 3.2-ton straight-fold boom crane machine.
9. What does the boom section of a truck-mounted crane mean?
ထရပ်ကား တပ်ဆင်ထားသော ကရိန်းs typically offer two types of booms: the folding boom and the straight boom. The straight boom can be further divided into two sections, three sections, four sections, five sections, and six sections. When not in use, all the boom sections can be retracted for convenience and storage.
10. How to select the slewing bearing for a truck-mounted crane?
Generally, the selection of the slewing bearing for a truck-mounted crane is based on the load-bearing curve. ပထမဦးစွာ, the static safety factor is taken into consideration. ပြီးတော့, calculations are made for the maximum working load, axial force, and overturning moment. နောက်ဆုံး, the static reference load of the slewing bearing is computed.
ကဲ, let’s delve deeper into some additional aspects related to truck-mounted cranes: When it comes to the maintenance ofထရပ်ကားတပ်ဆင်ထားသောကရိန်း၎, regular inspections of the crane’s mechanical components, such as the winch, pulleys, and cables, are essential. Any signs of wear or damage should be addressed promptly to prevent potential failures during operation. The hydraulic system of the crane also requires frequent checks for leaks, proper fluid levels, and the functionality of valves and pumps. Contaminated hydraulic fluid can cause significant damage, so regular fluid changes and filtration are necessary. In terms of safety precautions, operators should always ensure a stable and level working surface before operating the crane. Overloading the crane beyond its specified capacity is strictly prohibited and can lead to dangerous accidents and damage to the equipment. When transporting theထရပ်ကားတပ်ဆင်ထားသောကရိန်း, it’s important to secure all components properly to prevent any movement or damage during transit. Special attention should be given to the boom and any loose attachments. For those considering purchasing a usedထရပ်ကားတပ်ဆင်ထားသောကရိန်း, a thorough inspection of the vehicle’s history, including maintenance records and any previous accidents or damage, is crucial. It’s also advisable to have a qualified mechanic assess the condition of the crane and its components. The location and environment in which theထရပ်ကားတပ်ဆင်ထားသောကရိန်းwill be used can also influence the choice. ဥပမာအားဖြင့်, if the crane will be operating in corrosive or extreme weather conditions, special coatings or protective measures may be needed to prolong the lifespan of the equipment.
နောက်ဆုံး, staying updated with the latest industry standards and regulations regarding the operation and maintenance ofထရပ်ကားတပ်ဆင်ထားသောကရိန်းs is vital to ensure compliance and safe operations.
