LHEA Double-Trolley Electric Hoist Bridge Crane
For buyers who need two trolley lifting points but also want low headroom, low self-weight and reduced building loads.
Henan Mine Crane lhea double-trolley hoist crane product image showing the crane and lifting arrangement.
The LHEA double-trolley electric-hoist bridge crane is developed from the electric-hoist bridge-crane platform and uses two electric-hoist trolleys. It supports general intermittent material handling with hooks or special lifting attachments.
The source emphasizes low headroom, low self-weight and low wheel pressure. For procurement, this makes the product relevant when two lifting points are needed but building height or runway capacity is limited.

Product Overview
Two electric-hoist trolleys are used as the lifting mechanisms.
Can handle materials using hooks or special lifting attachments.
Low-headroom design uses seated hoists on trolley frames.
For a new purchase, any capacity, span, speed, duty or positioning value that is not published on the source page should be confirmed from the actual project rather than assumed from a similar crane.
Why Choose LHEA Double-Trolley Hoist Crane?
Two-Trolley Handling
Two trolleys provide two lifting points for long or varied loads.
Low-Headroom Design
Seated hoists on trolley frames improve vertical space utilization.
Low Self-Weight
Reduced crane dead weight can lower structural demand.
Low Wheel Pressure
Useful where runway and building loads are constrained.
Reliable Components
Forged wheels and Nanjing special drive components are source-highlighted.

Two-trolley handling with lower structural loads. |
| Assembly Workshops |
Balanced lifting and placement of fabricated equipment. |
| General Manufacturing |
Independent or coordinated material handling as required by the project. |
How to Select the Right LHEA Double-Trolley Hoist Crane
1. Define Load and Lifting Points
Provide total weight, load length and pick-point spacing.
2. Check Headroom
Provide roof and runway elevations to confirm vertical-space benefit.
3. Check Building Capacity
Share runway-beam and column details when low wheel pressure is a key purchase reason.
4. Define Trolley Operating Logic
State whether trolleys need independent and/or coordinated operation.
5. Confirm Span, Height and Duty
Complete normal crane sizing and operating-cycle data.
Safety & Control: What Buyers Should Confirm
- Rated-capacity and overload-protection requirements
- Upper/lower hoisting limits and travel limits
- Brake and emergency-stop requirements
- Electrical protection and site power conditions
- Operator control method and visibility
- Anti-collision, warning, synchronization or other project-specific functions where required
- Factory / site acceptance and load-test requirements
Installation & Maintenance
Before manufacture and installation, confirm runway span, rail or runway-beam condition, elevation, straightness, available headroom, electrical supply and erection access. Multi-trolley, suspended or cross-rail systems also require the relevant trolley spacing, support-point or transfer-interface data to be checked before production.
Maintenance should follow the final supplied crane manual and include the hoists, brakes, ropes, hooks / attachments, wheels, drives, fasteners, limits and electrical protection. Synchronized and multi-trolley systems should also include periodic verification of encoders, control logic and relative lifting position where applicable.

Frequently Asked Questions
Why choose LHEA instead of a standard two-trolley crane?
The source-defined advantages are low headroom, low self-weight and low wheel pressure.
Can special lifting attachments be used?
Yes. The source states that hooks or other special lifting devices can be used.
What building data should be supplied?
Provide runway beam, column and roof elevation information when building load and headroom are important.
Are exact trolley synchronization parameters published?
No. Any synchronization requirement should be defined separately in the project technical specification.
