Usage lifting device must have sufficient capacity. Before starting work, you must ensure the suitability of existing available in your possession lifter or device. Before the start of the lifting system should be removed additional load in the cargo compartment of the car. When hanging the whole car ascent should begin with Chuck. Under the rear wheels need to enclose the stops (or bricks) that the vehicle is not started at the beginning of the lifting movement. To do this, apply the parking brake. Podkatnye hydraulic jack mounted in the middle, under the front of the vehicle. If you decide to use the on-board hydraulic jack, which is equipped with a car, then it must be installed as shown in the upper part of Fig. 7, next to ladders fixing spring, just before the bridge girder. Lifting the car, you need to install the left and right sides under the beam reliable support to withstand a raised weight of the vehicle. It should be remembered that the supports conventionally used for the repair of cars, in this case unsuitable. The height of the pedestal is adjusted by the retainer being inserted in different holes rack support. In the process of their manufacture strength of the fastener is adjusted for load bearing. Experience shows that a chain of insert locks are often torn, and the clips themselves are lost.
A warning It is impossible in any case to use in such situations, any bolts suitable for the diameter of the holes, always use only steel fasteners suitable strength. |
Before hanging the car, make sure the properties of the ground (floor / base) to prevent sagging jack (hoist). If there are concerns that the set of support are not reliable enough, it is possible, for example, to lift one side of the car, remove the wheel and substitute it under suspension vacated. In this case, even if the car falls from the set of poles, between the vehicle and the floor (ground) will be clearance equal to the thickness of the wheel, which will also be an additional safety measure. The rear part of the car or lifted by a hydraulic jack podkatnye or using kit jack mounted under the rear axle of a vehicle, as shown in the lower part of Fig. 7. Supports shall meet the above recommendations. Since not all cars have the same space for the installation of the jack, then the following are some recommendations for alternative points for hanging a vehicle for changing wheels. In Fig. 8 (a-d) provides various methods hanging car.
