Lifting Hooks for Cranes
With the evo range of lifting hooks for cranes, elebia, the market leader in automatic lifting solutions will boost the safety and productivity of your cranes. The patented evo automatic hooks range from the 2.5 tons capacity of the evo2 crane hook to 25 tons capacity and allow you to hook on and release any load remotely.
The patented automatic hook is equipped with a magnet in its lower section. When the magnet is close to the load, it attracts and correctly positions the sling. The operator pushes the control button, the hook closes, catches the ring and lifts the load without any additional handling.
The automatic crane hook works with cable slings, chains slings, master links, textile slings and even big bags. With the unique elebia automatic hook, you will be able to pick up and release loads remotely, avoiding any handling and moving, minimising risks, enhancing safety and increasing productivity.
How does it work?
The automatic safety hooks lift and releases the load remotely. The remote controlled crane hooks generate a magnetic field that attracts and orients the sling, masterlink or rigging gear. The operator then presses the “close” button on the remote control to automatically close the lifting hooks for cranes, without any manual intervention, operating remotely from a safe distance.
We’ve redesigned the high capacity battery to improve efficiency and minimise energy consumption of the automatic hook. The battery is fully charged in 3 hours, and allows up to 5,000 cycles or 250 hours in standby mode.
Designed to work in the toughest conditions (steelworks, ports, low temperatures) and built with the best materials. WELDOX body of high strength steel, forged hook type T or V.
The evo range of lifting hooks for cranes was designed to enhance safety and increase productivity. It is designed under a fail-safe principle. The automatic hook CAN NOT drop a suspended load. This is a feature of all our designs, geometrically fail-safe, without any sensors or electric components.
Our automatic hooks come with a unique magnetic system, formed by 32 neodymium permanent magnets. These magnets are placed in a precise configuration that generate an oriented magnetic field with 3 functions: attract, center and orient the masterlink. The complete range of our automatic hooks carry this basic component, which allows the remote engage of loads.
Other options can also be configured with the automatic hooks:
REF.: OPTION S
A sensor in the magnet indicates when the masterlink is attached to it. This info is displayed in the eMAX remote control. Units with the magnet sensor can be configured in ‘Autoclose Mode’: the hook will automatically close when the magnet sensor detects the ring is in position. The magnet sensor’s sensitivity/trigger level can be adjusted to customer needs.
REF.: OPTION PM (Not available for evo2)
Increased magnetic power.
Power Magnet & Rigid Safety Latch
REF.: OPTION PMA (Not available for evo2)
Instead of the standard safety latch (movable, spring loaded), this is a fixed latch, forming a complete closed loop along with the automatic hook.
Void, No Magnets
REF.: OPTION V
No magnetic system.
The complete range of lifting hooks for cranes can be upgraded with a load cell to weigh the load that is being lifted. This cargo cell is accurate, powerful and fully integrated into the hook, representing no increase in weight or dimensions of the unit. The load cell is highly recommended for preventing overloads and as an additional safety measure. Load cells can also be retrofitted into older models of our hooks.
The load cell in combination with the eMAX remote control transforms all of our hooks into a precise weighing scale with advanced features.

The innovative position encoder has been integrated into the evo10, evo20 and evo25 lifting hooks for cranes representing an added safety element in all lifting operations. The encoder highlights a technical upgrade of our remote hooks, as it allows to know the exact angular position of the hook at any given moment thanks the information relayed to the eMAX remote control.
This important feature comes in very handy in operations where the operator can not see the hook’s position. The automatic hook’s status is displayed on the eMAX remote control, transmitting real time information to the operator.
With the position encoder and the eMAX remote control, the user is always aware of the hook’s status (open/closed) and is informed with the buzzer/vibrator and display features of the eMAX if the load is not placed correctly on the safety hook. (e.g. tip of the hook)
With the specifications of this advanced feature, the chances of impacts are reduced, the life-span of the motor and clutch increase and most importantly, safety is enhanced in all lifting operations.
The position encoder can be retrofitted into older units of the evo10, evo20 and evo25 (*except for versions with a spring loaded latch)
Simply open and close the automatic crane hooks or receive real-time information of weight, battery level, and other values of the lifting and manoeuvring operation.
Just like our lifting hooks for bell furnaces and automatic lifting clamps, the automatic crane hook can be paired to the eMAX, eMINI or Installable remote controls.
