FEATURE CRANES & HOISTS
V-TYPE DOUBLE GIRDER CRANE provides precise positioning
The reduced weight of the girder of the Demag V-type crane allows a rope hoist with a higher load capacity to be accommodated, enabling faster, gentler material handling

Terex Material Handling has extended the range to include V-type double girder overhead travelling models. V-type double girder cranes are available with load capacities of up to 50 tonnes and are offered with spans of up to 35 m as standard with longer girder lengths available upon request.
A significant feature of the V-type crane is the reduced weight of the girder compared with those manufactured in box section girders. This facilitates the accommodation of a rope hoist that has a higher load capacity for the movement of heavier unit loads. The reduced crane deadweight produces less wheel pressure, minimising the forces transmitted to the crane runways and building structures. Consequently, the Demag V-type crane provides architects with greater freedom in planning new factory buildings.
PRECISE POSITIONING OF SENSITIVE GOODS A further advantage over conventional box section girder design is that the V-type’s mechanically connected girders are inherently more rigid, enabling faster material handling and the ability to transport and position sensitive loads gently and accurately.
EASILY ADAPTED TO BUILDING STRUCTURES The V-type double-girder crane is offered in four designs with the side connection of the end carriages to the girder a common feature to all models. The different types are distinguished by the shape of the girder ends and their vertical connection position, ensuring
that the crane design may be best adapted to the existing building. For new structures the space between the crane and building roof may be reduced for construction cost savings and lower maintenance expenses. In existing buildings with sufficient headroom the height of the V-type girder can be increased to further reduce crane deadweight. This provides benefits for applications where the load bearing capacity of the building is an issue.
TORSION-FREE CRANE GIRDERS
The Demag V-type double girder crane offers improved precision for its crab runway. By placing the crab rail in the
ELECTRIC CHAIN HOISTS HANDLE LOADS UP TO 5000KG
VERLINDE´s new range of electric chain hoists has been extended to cater for loads for up to 5000kg. With its entirely ergonomic design EUROCHAIN VR ensures best safety and productivity levels while facilitating maintenance. Designed to ensure maximum user safety, the standard version is fitted with a new hoist load wheel concept with intermediate teeth for the drive chain, 2 lifting speeds, a Start/Stop palm button on the control box, torque limiter, hoist disc brake, very low voltage control system (48V), a variable speed
travel motor, an electric safety limit switch for high and low positions and it complies with the EC machinery directive. Options available on EUROCHAIN VR16 and
EUROCHAIN VR25 include gear limit switch, second brake on the hoist motor mounted with a lug replacing the top hook, automatic closing of lifting hook, travel limit switch, short headroom trolley, curved track trolley and 2-speed travel trolley.

The V-type double girder design allows much more light to pass through which improves line of sight within the building and creates a brighter workplace for a safer working environment
middle of the V-type crane girder the distribution of forces is balanced and the crane girder remains torsion-free. The V-type design with vertical struts
means that the load dependent forces exerted by the rope hoist crab are transferred vertically to the girders, resulting in minimised wear on the crab rail and crab trolley system. This ensures that the track gauge of the crab runway is maintained precisely.
MORE LIGHT FOR IMPROVED WORKPLACE SAFETY The V-type double girder design allows much more light to pass through it than traditional solid crane girders. This improves line of sight within the building and creates a brighter workplace for a safer working environment. “Following the positive response from the market for our V-type single girder crane we have taken the next logical step with the introduction of the double girder design,” comments Andreas Hambrock, senior director of the Universal and Modular Cranes’ Business Line at Terex Material Handling
