  1. 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD The Knowledge of 1-10t Balance-weight Type Forklift Truck with Engine HELI CHINA 2012.01

  2. The Types of Forklift 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 1、According to power types, forklift can be divided into two major categories of internal combustion engine forklifts and electric forklifts. 2、According to structure types and the methods of stability, forklift can be divided into balance-weight type trucks, reach type trucks, straddle type trucks and sideway type trucks. 3、 According to transmission types, forklift can be divided into Mechanical transmission type trucks and Hydraulic transmission type trucks.

  4. The Brief Introduce of HELI 1~10t Forklift 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 1 to 3.5 ton gasoline/diesel/LPG(Liquefied petroleum gas)/gasoline or LPG forklift trucks with clutch/torque converter have 3 series: α, H and G in HELI. 5 to 7 ton gasoline/diesel/LPG(Liquefied petroleum gas)/gasoline or LPG forklift trucks with torque converter have 2 series: X and H in HELI. 8 to 10 ton diesel forklift trucks with torque converter have 1 series: H in HELI. The tonnage distribution in HELI is 1t、1.5t、1.8t、2t 、2.5t 、3t 、3.5t、 4t、4.5t、 5t、6t 、7t、8t 、10t 。 For example, CPCD50-CU3 ( CP: balance-weight forklift truck; C: diesel; D:torque converter CU: Cummins engine made in USA 3: NO.3 type)

  5. THE CONTRAST OF HELI TRUCKS WITH OTHERS 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 1、HELI design and manufacture drive system ourselves. Our machine devices keep ahead in the international. The key components of transmission which has lower failure rate are the best in the international. The quality of HELI transmission is NO.1 in CHINA. 2、Brake system apply a type of hydraulic dynamic braking system, and hydraulic spring storage (5-10t) that termination pressure ≥10MPa, oil volume ≥100ml. You may only consume a little strength for pressing the pedal. The reliability of system is very well, and it has higher efficiency. 3、The mast which may fix many types of attachments has double internal hose pulley assembly, and do not need to apply hose reel device. This design can reduce your costs, increase the beauty of truck and the sheave space. 4、All hydraulic lines of mast have some explosion relief valves for safety while lifting goods. 5、The link between exhaust system and frame are bellows, can cut down more vibration and noise.

  6. THE CONTRAST OF HELI TRUCKS WITH OTHERS 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 6、The junctions of steering axle and frame have been redesigned for reducing vibration. The truck’s vibration reduce 30%. 7、Muffler expand and interference the airflow which going in engine, inhibit the inlet pulse, and reduce the inlet noise. 8、All types of hose connector and transition connector in pipeline apply cone sealing form which effect is very well. Do not need ring, and will have not any oil leakage in a long time. 9、The key seals all come from Japan or German. 10、Steering trapezoiddesign apply optimization program. it’s error angle＜1°,and can reduce more abrasion of tires. 11、16 automatic tests can detect torque, speed of engine, oil temperature, oil pressure, and so on. More 10 parameters can be show, memory, count, analysis and output in real time.

  7. THE CONTRAST OF HELI TRUCKS WITH OTHERS 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 12、About differential , a pair of spiral bevel gear impacting noise should be checked one by one, especially noise inspection which can ensure the prevention of howl. 13、Torque converter has been designed and manufactured on the basis of Japanese technology, and now has been improved for HELI trucks, make the efficiency increase 2% to 3%. 14、 G series forklift trucks have apply a type of muffler , can eliminate many types of noise such as LF, IF, HF, and can reduce noise outside the truck or outside driver ’ s ear. 15、 The mast of G series forklift fix a type of buffer device, can reduce some vibration and pound. 16、 The human design of G reduce the pressure of pedal, relieve our arm’s fatigue, improve driver’s vision. More safety and more cozy. No apply asbestos. 17、The safety of G is very well. It have all types of protection facilities , especially operating sensing system.

  8. THE CONTRAST OF HELI TRUCKS WITH OTHERS 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 18、For G, its main oil pump displacement is low, but lifting speed is high, Hydraulic oil temperatue is low, fuel temperature is low, traction and climbing ability all are high. 19、G forklift trucks’ emission are lower than others, correspond the last standard of EC in Europe and EPA in USA. 20、 G may apply a tape type cab, which can ensure truck’s safety. 21、G fix a type of intelligent parking brake system, can ensure truck’s stillness at any circumstance. 22、The design of low-energy can reduce some loss of energy and torque.

  34. DRIVE AXLE 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 1、Drive axle The drive axle(5 to 10 ton) that consists of a main reduction, differential, hub reduction and brakes as shown in fig is bolted to the front side of the frame. The masts are installed on the axle housing. The drive axle(1 to 3.5 tone) have no hub reduction.

  35. DRIVE AXLE 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 2、Working theory The power is transmitted to the halfshafts through the differential and drives the front wheels through the hubs.Each hub is fixed on the housing with two tapered roll bearings, so that thehalf-shafts bear only the torque transmitted to the hubs, In the inside of the hub are oil seals to prevent water and dust from entering and oil leakage.

  36. STEERING SYSTEM AND STEERING AXLE 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 1、Characteristics The functions of forklift trucks are loading, unloading, and transporting in a finite distance. Because the smaller working ground and frequent turning, the trucks need high-powered steering system which is flexible and agile very much. 2、Components of steering system The steering system of forklift truck is a set of machines that can be control by driver, make the wheels turn left or right. The system include: 1）control device: (including handle shaft, turning shaft, steering column, locking device of handle shaft)transferring and magnifying the torque of handle shaft from driver, and change turning to swing of steering rod units. 2） steering rod units: make turning angle of the inner wheel is different from the outers, accord with steering disciplinarian. 3）supporting device：(including knuckle, king pin, and steering axle)support rear wheels and limit steering of wheels circling king pins. 4）Hydraulic pipeline(only for hydraulic type powered steering system)

The supporting positions which are axis and bush locate middle, front, and rear of axle body. The axis is been fixed in the frame of truck, also may swing a little. 1-Body2-Tie rod3-Steering cylinder 4-Knuckle 5-wheel

  39. BRAKE SYSTEM 安徽叉车集团有限责任公司 ANHUI FORKLIFT TRUCK GROUP CO.,LTD 1、General description The brake system can make the forklift truck run slowly or parked, also control truck’s speed when declivity or parking on the ramp. The brake system must have the best safety, can ensure the security of truck and driver. The system consists of brake control and parking system. The brake control and parking system all have been controlled by wheel brake for 1-3.5t. In 5-10t trucks, brake control is fixed in drive wheel, while parking brake is fixed with a axle in transmission. The types of brake system are hydraulic brake(for 1-3.5t), brake commixing baric and hydraulic, hydraulic type powered brake(for 5-10t).
