How to maintain and use a pit lift?

Repairs and maintenance of trucks, buses and other heavy vehicles are usually done using service pits. Because of the large dimensions and weight, column lifts require more space and longer preparation to lift a truck or bus. However, inspections of vehicle services for both trucks and buses achieve a high cycle time, making it much more convenient to use pit lifts. Which are suitable for high working speeds and bulky vehicles.

One of the most popular pit lifts in Lithuania is the manufacturer of AC Hydraulic, which are produced in Denmark. They are so confident in their durability, technology and engineers that all their equipment comes with a warranty of up to 10 years. The 3-year warranty applies to the hydraulic system (pump and cylinder), the 10-year warranty applies to frames, chassis, construction, and the spare parts are covered by a 15-year warranty.

However, the AC Hydraulic warranty is just one nuance that sets it apart from the competition. The equipment of this manufacturer is characterized by a particularly fast and precise hydraulic device, the stroke of which is not only lowered but also raised. These are space-saving and easy-to-use pit lifts that do not have any external oil supply pipes and hoses, making the system less vulnerable. And because of the robust and reliable design of all lifts, the lifts have the least maintenance requirements.

However, the main feature of AC Hydraulic pit lifts is that they are almost always made to your pit dimensions. So you will not have to adapt to the equipment you buy, but we will adapt to your needs. However, keep in mind that in order to purchase the most suitable pit lift, you will need to fill out the pit lift specifications form according to which it will be manufactured.

What you need to know about the operation and maintenance of pit lifts:

• The rails for pit lifts on which they will travel must have a uniform area and must not widen or narrow;

• Max. rail inclination can be 2 mm / m, max. the difference in rail height on both sides may be up to 10 mm and the maximum narrowing or widening of the rails may be up to + -6 mm;

• The front axle wheels must be straightened and the parking brake applied before lifting the truck or bus;

• The minimum distance between operating pit lifts when the vehicle is being lifted is 3.5 meters;

• If you notice that when lifting a truck or bus, it is moving to one side or the other, you need to reposition the pit lift and find the right balance point;

• Pneumatic pit hoists that use a compressor must be equipped with a moisture filter with lubricant attached to the compressor;

• ISO VG 5 (or ISO VG 15) hydraulic oil must be used and not the DOT brake fluid often used in practice;

• The truck and bus must only be driven when the well lift cylinder is fully lowered;

• The pit lift must not be washed with high pressure equipment and tools, it must be cleaned with cloths;

• The hydraulic cylinder must be maintained so that there are no solid particles on it that could scratch it;

• The wheels of the pit lifts must be completely on the rails with the entire body up to the spreading part;

• Do not use the pit lift if its body is cracked, the hydraulic cylinder is bent or hydraulic oil is dripping through it;

• Pit lifts that run on rails on the pit floor are perfect for use not only to lift a heavy vehicle, but also to lift transmissions;

• When lifting transmissions with floor pit hoists, never forget to fasten the transmission itself to the hoist;

• When lifting trucks and buses, people must be disembarked from the vehicle and it is recommended that there are no people around.
