In accordance with Section 7 of the Use of Work Equipment Regulations, the acceptance must be carried out in Austria by a sworn civil engineer.

See ramp.

Indicates whether the hydraulic unit is installed underneath the platform (internal) or whether it is arranged separately, near to the lifting table (external).

There are internal and external aggregates. External aggregates enable the lifting table to be more even. The aggregate consists of the motor, the hydraulic pumps, the tank and the valve block.

In hydraulic systems, the ambient temperature is important to the design of the lifting table. Extreme ambient temperature values must be detected. Too high or too low temperatures require special measures, such as oil cooling or oil heating.

Forces acting in the direction of an axis.

The substructure of the lifting table. The base frame drives the forces acting on the lifting table towards the ground.

Bio-oil is biodegradable hydraulic oil. It is used if an environmental hazard may arise due to oil leakage.

Bolt locking mechanisms mechanically connect the lifting table to a wall. The lifting table is therefore stable during loading and unloading.

The control circuit is connected to the main circuit. It is used for the activation and control of the valves. In most cases, the control circuit has a voltage of 24 V or 12 V.

Indicates the number of cycles that a table can/should complete per hour.

Indicates the time between one motor start and the next motor start during lifting, or the time between one valve opening to the next valve opening during lowering. For short cycle times during lifting, i.e. several motor starts per hour, it is advisable to implement an aggregate with pressure-less circulation. This way, the engine will continue to run, and the lifting and lowering can be controlled using the valves.

Short form of the lifting cylinder, which operates in the scissor lift.

A dead man’s switch is a control method. It is not automatic – the control pulse is generated by buttons. If the button is not repeatedly pressed, no more action will be taken.

The remaining difference in pressure can be deflected by loading or unloading a table.

The door locking system locks any existing doors on the lift table or doors on the shaft at the customer’s site.

The cylinder is filled with hydraulic fluid from both sides of the piston. This results in the table being lowered by a hydraulic unit, as opposed to the weight of the platform and the load.

Double-scissor lifting tables have 2 scissors – one on top of the other. This design allows greater lifting heights and shorter platform lengths.

A pair of bellows is a protective device which is mounted underneath the lifting table platform, and which expands or contracts when the table is raised or lowered. A pair of bellows protects the area below the platform against dust, and also prevents personnel from reaching into the scissor lift. A form of underflow protection, usually used for dust protection.

The speed at which the lifting table is lowered when it is loaded.

The lowering time indicates the time taken for the lifting table to go from its maximum extended position to its lowest end position. The lowering time may vary due to the load on the lifting table. In order to achieve a constant lowering time, a double-acting cylinder is necessary.

Maintenance supports must be placed under the platform prior to carrying out maintenance or repair work. They prevent the platform from lowering.

Unlike the emergency stop button, the master switch cuts off the entire power supply of the system. It is necessary for system maintenance or repairs. The main switch must be lockable so that the machine can be safely shut down.

A normalized colour table, from which the colour of the lift table is selected.

It is usually necessary for a lifting table to be driven by a forklift or pallet truck, to compensate for the construction height.

The easy lowering of the lifting table when it is loaded in the extended position. This lowering is caused by the compression of the hydraulic oil or the expansion of the hoses, and the deflection of the scissor construction.

A relay is an electromagnetic switch. A contact is tightened or loosened by a control voltage.

Secures a load, e.g. on wheels, before it rolls off. There are manual and automatic systems. While the manual systems are usually pluggable, automatic systems normally have a lever mechanism that extends when the platform is raised.

The roller blind is a form of underflow protection consisting of a spring shaft and a rolled up PVC or fabric curtain that automatically rolls up or unrolls when the platform moves. The roller blind is positioned on the outer edge below the platform.

The rotor is the movable (rotating) part of an electric motor. The rotor is also known as an armature.

The safety edges are positioned on the outer edge below the platform. The lowering of the platform is interrupted when the safety edges are activated. This therefore prevents, for example, feet being crushed by the platform edge.

The scissor lift construction causes the platform to move upwards and downwards, usually by means of a lifting cylinder.

The viscosity indicates the thickness of a liquid.

The volume flow is the measurement unit that indicates how much volume is flowing through a certain cross-section at a specific time. The volume flow decisively influences the lifting and lowering speed.
