ELECTRIC CHAIN HOISTS

What is included with an electric chain hoist?

The electric chain hoists are operated through a pendant control handset and cable, so you are ready to plug in and start work straight away. You will receive your electric chain hoist with a high-tensile galvanised chain with chain container, a hinged and removable suspension bracket and overload protection via a slipping clutch, which is adjustable without having to take the hoist apart (for hoist types GM 2/4/6/8).

The standard equipment includes a safety slipping clutch as reliable protection against overload with minimal wear. The quick plug-type connectors with error-free twist locks enable a fast, easy electrical connection. The specially hardened and galvanized chain is designed as a steel profile chain and has, therefore, a 25% higher load capacity than a comparable round steel chain, which offers additional safety and a longer service life.

How is the electric chain hoist controlled?

The smallest size GMC (operating voltage 230 V) with electronic control lifts the loads using a step-less inverter.

The chain hoist types GM 2/4/6/8 are equipped with contactor control using semiconductor technology which provides 48v low voltage control. These four sizes run at an operating voltage of 380-415 V / 50Hz however special voltages are possible on request.

What performance features does the chain hoist have?

In addition to the five hoist types, various lifting speeds, load capacities and hook paths are available. The electric chain hoists can also be reeved single or twin-fall. With the single-fall chain hoist, the chain runs directly from the lifting unit to the hook. On a double-reeved chain hoist, a pulley is located in the bottom block. The chain runs back to the housing and is attached there. According to the proven principle of the block & tackle, the maximum load capacity is doubled at half the lifting speed. 

Extensive additional equipment complete the electric chain hoists

The chain hoists can travel with manual trolleys (push trolley) or electric trolleys on an I-beam (trolley track). The flange width range for our trolleys is between 42 – 400 mm and they are adjustable to suit your requirements. If more than one chain hoist travels on a beam, special buffers serve as collision protection. At the end of runway, a clamping buffer limits the travel distance.

As standard equipment, the electric chain hoist can be equipped with a radio remote control, which has an effective range up to 50 m. If the electric chain hoist and electric trolley is delivered with a radio remote control, an electric trolley travel limit switch (cross-type limit switch) is also included. It stops the trolley automatically at the end of the working area.

Safety load hooks are available for production areas with the highest safety requirements. The load cannot be unhooked accidentally. When under load, the load hook closes and it can then only be opened by pressing the locking release when the hook is no longer under load.

The electronic hoist limit switch provides additional safety. The freely selectable switching points for a highest and lowest hook position are individually adjustable by the operator via a teach-in button in the pendant control or if required by a separate unit for use only by your maintenance department.  

For the transport of sensitive goods, we recommend our ABULiner frequency converter for an infinitely variable and smooth lifting operation. This makes the exact positioning during difficult assembly and joining processes considerably easier.  

In order to facilitate the connection of underhook equipment, we can also provide our electric hoists with a 5-pole (3/N/PE) power socket. This makes it easy to establish the power supply for an additional device (e.g. vacuum system). 

What lifting technology advantages does an ABUS electric chain hoist offer?

An ABUS electric chain hoist combines many advantages: It impresses with its simple operation, high duty cycle, low dead weight and a high load capacity. Furthermore, the lifting devices are robust, reliable and low-maintenance.

The electric chain hoists are built and tested according to European standards, rules and regulations. They are subject to periodic inspections in accordance with LOLER regulations but they should also be serviced regularly. We will be pleased to carry out both the statutory inspection according to LOLER and also to service the hoist for you so you can benefit from the ABUS 4 Year extended warranty. Please contact our office for further information.

Our series of chain hoists ABUCompact is designed for easy maintenance. When service is needed, for example to replace a worn chain, only a few screws have to be loosened and the chain including the chain guide can be pulled out and replaced with a new one.
