6 Ton Electric Hoist Cross Travelling | Low Headroom Crab Trolley
Short Video Description
This video shows a 6 ton electric hoist cross travelling system with a low headroom electric hoist and crab trolley for a double girder overhead crane. The trolley is designed to travel across the two main girders while providing a compact hoisting arrangement.
The 6 ton low headroom hoist is suitable for double girder overhead cranes where the customer needs better hook height and efficient use of the available building clearance. The electric hoist trolley combines the hoisting mechanism and cross-travelling mechanism into one compact crab trolley.
For a double girder crane with electric crab trolley, the hoist trolley travels on rails installed on the top of the two main girders. The cross-travelling movement allows the 6 ton hook to cover the working area between the crane end carriages.
The low headroom arrangement can be engineered to reduce unnecessary vertical space between the crane girder, hoist trolley and hook. This is particularly useful for 6 ton double girder overhead cranes installed in workshops with limited building height.
The final trolley design depends on the 6 ton lifting capacity, crane span, lifting height, duty class, cross-travel speed, available headroom and required hook approach. Yuantai engineers select the hoist, trolley frame, wheels, motors and electrical configuration as one complete system.

FAQ: 6 Ton Electric Hoist Cross Travelling & Low Headroom Crab Trolley
Common questions about 6 ton electric hoist trolleys, low headroom crab trolleys and double girder overhead crane cross travelling systems.
1. What is a 6 ton electric hoist cross travelling trolley?
A 6 ton electric hoist cross travelling trolley is a motorized crab trolley that carries the electric wire rope hoist and travels horizontally across the two main girders of a double girder crane.
It provides cross-travel movement so the 6 ton hook can reach different positions across the crane span.
2. What is a low headroom hoist trolley?
A low headroom hoist trolley uses a compact arrangement of the hoist, trolley frame, wheels and travelling mechanism to reduce the required vertical space.
It is useful when a workshop has limited clearance and the customer needs to maximize the available hook height.
3. Can a 6 ton low headroom hoist be used on a double girder crane?
Yes. A 6 ton low headroom electric hoist can be installed on a double girder crane using a suitable crab trolley arrangement.
The trolley frame, wheel loads, girder design and available headroom should be checked together before the final configuration is selected.
4. What is the difference between crane travelling and trolley travelling?
Crane travelling moves the entire bridge along the runway rails, while trolley cross travelling moves the hoist across the main girders.
The two movements work together to position the 6 ton hook within the working area of the overhead crane.
5. What technical data is needed for a 6 ton hoist trolley quotation?
Provide the 6 ton capacity, lifting height, crane span, required cross-travel speed, lifting speed, duty class, available headroom, power supply and application.
A crane drawing showing the main girder dimensions and required hook height can also help Yuantai engineers determine the suitable low headroom trolley arrangement.
6. Can the 6 ton crab trolley use VFD control?
Yes. VFD control can be applied to the trolley and, when required, the hoisting mechanism to provide smoother starting, stopping and load positioning.
The control configuration is selected according to the working conditions, duty class and customer's positioning requirements.
7. What experience does Yuantai Crane have with electric crab trolleys?
Yuantai Crane has engineering and manufacturing experience with electric wire rope hoists, crab trolleys, double girder overhead cranes and low headroom hoisting systems.
For a 6 ton project, Yuantai engineers check the hoist, trolley frame, cross-travel wheels, motors, main girders, wheel loads and hook height as one complete crane system.
