Installation and use of the winch on wrecker truck

Hydraulic winch is widely used in the repair car, it is an important feature, they can be used for lifting and towing tractor(for wrecker tow truck), hydraulic winch from light to heavy have many specifications, the commonly used hydraulic winch has worm gear and worm and planetary gear reduction two kinds of structure, winch driven by hydraulic motor, through the reduction gear to achieve the purpose of the slow down and increase the output torque, so as to realize the relative overloading of capstan drawing ability, worm and worm wheel type hydraulic winch is relatively simple in structure, make easy, transmission efficiency and production costs are relatively low, generally used for MLJ hydraulic winch, and the planetary wheel type hydraulic winch structure is relatively complex, Large transmission ratio, transmission efficiency and production cost is relatively high, generally used in medium and heavy hydraulic capstan.

wrecker tow truck

On the repair car, hydraulic winch used more in the place of installation, and offset the hydraulic winch is gradually applied on some repair car, general repair car installed on one or two winch, according to the needs of design, the winch wire rope can be used both up and down the line direction, in order to better prevent disorderly rope, wire rope on the winch shall be equipped with pressure guide rope device, repair car of the winch and the selection of wire rope and installation is very important, it relates to technology and safety performance of the vehicle, therefore should note: when installing and using

(1) before the installation of the winch to check whether the parts are complete, there is no damage phenomenon, such as parts damage, must be replaced after the installation.

(2)The winch with the connection base or bracket should be mechanical for 10.High strength bolts of grade 9 or above are fixed to ensure adequate bond strength.

(3)After the capstan installation, to check the hydraulic pipeline is wrong, clutch can be normal combination, separation, capstan drum can be normal rotation, can not appear stuck phenomenon.

(4)In winch winding wire rope, the rope head into the drum hole, and then tighten the screw, and in the rewinding condition, winding 4-5 circles, loading 3-5kn force to wire rope wrapped.

(5)Wire rope around and around the drum when the maximum Angle of not more than 3 °, in case the rope and the winch force deflection.In the out of service, the wire rope pressure device will be pressed tight, to prevent loose wire rope and random rope.

(6)After the installation of capstan, in the heavy load test before or long time to use when the idle running, in order to facilitate the smooth running of the motor.

It is strictly prohibited to take off the capstan clutch during the hoisting of heavy weights or pull-up, during the operation of the capstan, the steel wire rope has at least 5 rings on the drum.
Therefore strictly prohibited capstan overload use, in case of damage to the capstan and a safety accident.

The Maintenance of LED Advertising Truck

 The generator is an important part of the LED advertising truck , and it is the power supply system of the whole truck. Except for the fixed-point parking of our advertising vehicles and plugging in an external power cord for playback, our generators are needed for power supply at other times. Therefore, in order to do a good job in advertising, we must pay special attention to the maintenance of our advertising truck generators. So how do we maintain our LED advertising truck generator? First of all, we have to regularly check the generator of our advertising truck, especially the inspection of the generator oil, and change the oil frequently. Take out the oil dipstick 20 minutes after it is not started or shut down, wipe the oil dipstick with a clean rag or paper towel, reinsert it into the oil hole for 10 seconds, and then take it out to ensure that the oil reaches the middle and upper parts of the lower and upper marks on the oil dipstick. Secondly, we need ...

Welding Process of Fuel Tank Truck

  CLVEHICLES.COM has a tank body welding process for fuel tanker truck . Many users who use oil tankers must also want to know how the tanker is made. Now I will introduce the welding of the oil baffle. Welding of the oil baffle plate of the refueling truck: the main work is the welding of the oil baffle plate in the cylinder body. According to the above, three oil baffle plates are generally arranged inside the 6M long cylinder body, and the cylinder body is divided into four compartments. Each oil baffle plate The plate must be intermittently welded with the cylinder body. If it is a separate tank, the oil baffle will be replaced by a partition, and continuous welding must be carried out. The length of each girth weld is based on the aforementioned 6-7.5M length. The continuous welding is calculated according to half of the welding length. The total welding length of this station is about 20M, and the welding speed is calculated at 5mm/s. The welding time is about...
Sprinkler truck maintenance in low temperature: 1、 When starting, pay attention to moderate heat:it is a good habit to start a moderately hot truck before starting the car. First idle for about 1 minute, then let the car run slowly for a long distance. The long-term in-situ hot car will increase fuel consumption; Operating the air conditioner at idle seed consumes fuel in particular. 2.When driving, pay attention to gentle refueling, and avoid stepping on the throttle. Cooling system, check the water tank, water pump and belt, water pipe, water supply tank and other components regularly in low temperature weather, especially for suction pump. If there is damage or malfunction, it is best to promptly, repair or replace. 3.Avoid low-speed at high-speed driving: sprinklers should avoid low-speed at high-speed driving, in addition to easy to lose grip, the engine speed is too high, it will be a little”only drink oil does not walk”. 4.Chassis: it is best t...
