The scissor lift is a technique that provides the delivery of employees and goods to a height. The system is driven by levers and hydraulic drive. The working platform moves strictly vertically, which allows you to operate the unit in confined spaces.
Benefits
The main advantages of scissor lifts:
- compact dimensions;
- ease of use;
- versatility;
- high reliability parameter;
- good load capacity.
The technique under consideration allows solving various construction and repair tasks. The range includes universal models focused on work outdoors and indoors. For warehouse or small spaces, a mini version is suitable, which has good maneuverability and noiselessness.
Electric scissor lift replaces several regular tools and fixtures (ladder, ladder, scaffolding, jack). Specifiedmodification does not require installation of additional and auxiliary devices. In addition, the speed of delivery of crews or cargo to the required height is significantly increased.
Application
The technique in question is mainly used in the construction and automotive sectors. The lifting height of the platform is adjustable by 10-20 meters, some modifications have a load capacity of about 10 tons. Depending on the size of the platform, one person or a group of workers can work on it at the same time. Scissor lifts are used in the construction of bridges, buildings, other high-rise objects, assembling and repairing machines.
In addition, these installations are used by companies involved in the advertising business, installation of windows, air conditioners and other installation and finishing works at height. Compact units allow you to solve various problems indoors. The advantages of the equipment include noiselessness, small size, tires that do not leave marks on the floor, no harmful emissions.
Design features
The devices got their name due to the original appearance and the principle of operation of folding levers similar to scissors. The working elements are driven by hydraulics, powered by an electrical network or battery. The structure is controlled by a remote control, the mechanism is mounted on the platform.
The cost of construction and car scissor lift is determined by the level of safety of the installation. On themodern modifications, the frame immediately deactivates the drive, in the event of an emergency. Optionally, the settings can be supplemented with motor protection, smooth braking, emergency descent, platform speed adjustment.
Varieties
Distinguish between mobile and self-propelled scissor lifts. In the first case, the equipment is delivered to the workplace on a trailer or by towing. Some models are equipped with wheels, while they cannot move independently, due to the lack of a traction motor. They are attached to a tractor or other vehicle of the required power. For short distances, the unit can be moved manually due to its low weight and compactness.
Self-propelled versions are equipped with wheels or caterpillars. The second option is not very popular, it is used where a high cross-country ability on heavy soils is needed. In the premises, the machines are equipped with special tires. Equipment with electric motors is suitable for indoor use, diesel counterparts are allowed to operate outdoors.
Car service lifts
The considered types of lifting installations are actively used in automotive services and service stations. Despite the fact that the scissor versions are somewhat more expensive than the classic two-rack modifications, they significantly save usable space and have a large working resource. Using this technique, it is easy to diagnose or repair a vehicle, perform tire fitting orcamber setting.
Before purchasing lifts for a car service, you need to pay attention to a number of points:
- carrying capacity indicator;
- lift height;
- working speed;
- energy consumption;
- work platform size;
- type and weight of the unit.
Safety and accessories
Outriggers guarantee good stability of these devices in the working position. It happens that the working surface on which the installation is placed is uneven. In this case, special pillows are used. They are quite affordable, greatly expanding the possibilities of adaptation.
Despite the wide range of scissor lifts on the market, some customers have individual proposals for the configuration and functionality of the unit. Equipment can be obtained by special order. The price in this case will be higher, but the practicality and efficiency is such that is necessary in a particular case. Taking into account additional functionality and safety factors, the unit can be equipped with the following equipment:
- sides folding configuration;
- roller shutters or doors;
- lift control;
- rollback platform;
- light indication elements;
- fencing net.
Selection criteria
The cost of scissor lifts directly depends onnominal load capacity specified in the technical data sheet. In addition to the maximum weight that the unit can lift, its working height must be taken into account. Indoors, 3-5 meters is quite enough, and on the street, it is advisable to select this indicator from 10 meters and above. The performance of the procedure depends on the high-speed mode of raising and lowering the platform. This parameter is calculated by the number of lifts for a certain time period or in the total mass of movements in one hour. The weight of the lift is important for mobile modifications, since its relatively low price will not play a beneficial role if constant costs for the rental of transport equipment are required.
