Electric cranes - eQuip

X

Linear actuator

With traditional machines, hydraulic cylinders are used to perform linear movements. For electric machines, eQuip uses robust, self developed electro-hydraulic linear actuators. This development has been crucial in the electrification of machine drives. In this product, all benefits of hydraulics (such as simple overload protection and shock- and vibration resistance) and electronics (such as high energy efficiency and low maintenance) come together.

Electric motor

Electric motors are of course available in countless variants and designs. The electric motor is used to convert electrical energy into mechanical energy. Traditional electric motors are heavy and relatively large. eQuip's electric motors find their origin in the automotive market, where a lot of developments are taking place. These developments have caused them to be very compact, light and robust. As a result, there are a lot of possibilities to convert new and existing machines to electrically powered solutions.

Energy storage system

There are various types of batteries. For professional usage Lithium-ion batteries have become the standard. This generation batteries does not suffer from a memory effect and have a very high energy density.

X

Control inverters

We use a control inverter to convert direct current (from the battery) to alternating current, with which we control the actuators in torque/force and speed. This control is extremely accurate and quick and is accompanied by high efficiency of approximately 99%. Dependent on the application, we might opt for singular or multiple control inverters. We also have special inverters for the regulation of voltage and charging of the batteries.

Linear actuator

Up to 90% energy reduction can be achieved with this passively compensated electrohydraulic actuator. This is because part of the load is carried by a volume if gas, which acts like a spring. For cranes, this is ideal.

Electric cranes

The advantages of electric cranes are getting more and more relevant, not only in construction but also in the maritime/offshore sector, due to the high power applications. Electrically powered cranes can save costs and energy consumption, mainly due to the fact that the required power and maintenance can be reduced. The largest improvements can be achieved with heavy compensation systems, where eQuip offers various innovative solutions which buffers the energy between cycles. This can lead to 90% energy reduction compared to traditional hydraulic systems.

eQuip's products can be integrated in existing cranes, but we can also work together from the design phase to achieve the best drive concept.

The advantages

NO EMISSION

Electric cranes produce no emissions. This benefits both public health and the climate. With zero emission, you meet current (or future) regulations, which gets you ahead of your competitors.

HIGH POWER DENSITY

The notion that electric motors are large and not powerful is one that belongs to the past. The power density of electric motors is higher than a combustion engine and similar to a hydraulic motor. Lightweight and powerful.

LOW ENERGY CONSUMPTION

Technological development has led to far better batteries. The battery life is now more than enough for a work day. This is partly due to the efficient regeneration during braking movements.

LOW MAINTENANCE

Electrically powered cranes are very maintenance-friendly, because they have (much) fewer moving parts than traditional cranes.

LESS NOISE NUISANCE

Electric motors produce far less noise than combustion engines.

NO PIPING SYSTEMS AND FILTERS

Electric cranes do not have any piping systems and filters. This lowers the costs and assembly time of the machine.
