LHE Double-Trolley Electric Hoist Bridge Crane

For buyers handling long, multi-point or varied loads that may require two trolleys to work independently or together.

The LHE double-trolley electric-hoist bridge crane is intended for general industrial material handling where one crane needs two lifting points. The two trolleys can work independently for separate loads or cooperate for tandem lifting of long or awkward components.

For procurement, the key questions are the total suspended load, load length, center of gravity, spacing between lifting points, required trolley synchronization and whether the two trolleys must also perform independent production tasks.

Product Overview

Electric hoist bridge crane for intermittent and repetitive general industrial handling.

Load handling device can be a hook or another special lifting attachment.

Wire-rope electric hoists provide a compact lifting mechanism with small overall dimensions and a large working range.

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 LHE Double-Trolley Hoist Crane?

Two Lifting Points

Two trolleys allow the crane to support long or multi-point loads that are difficult to control with one hook.

Independent or Combined Operation

The source confirms each trolley can operate separately or the two can work together.

Compact Hoist Mechanism

Wire-rope electric hoists help preserve working space and reduce mechanism dimensions.

Smooth Travel Control

Soft-start or VFD travel reduces shock during bridge and trolley acceleration.

Synchronization Capability

Encoders and inverter-control technology support coordinated two-trolley operation.

Application Scenarios

How to Select the Right LHE Double-Trolley Hoist Crane

1. Define the Total Suspended Load

Include both trolleys' lifted loads, rigging, lifting beams and attachments.

2. Provide Load Length and Lifting-Point Spacing

Trolley travel range and coordinated lifting depend on the actual pick points.

3. Define Synchronization Requirement

State allowable hook-height difference or load tilt during tandem lifts.

4. Confirm Independent-Operation Needs

Explain whether each trolley must handle separate jobs and what each trolley's maximum load will be.

5. Confirm Span, Lift Height and Duty

Complete the standard bridge-crane parameters after the tandem-lift logic is clear.

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.

What Information Do We Need for a Quote?

Frequently Asked Questions

Can the two trolleys operate separately?

Yes. The source explicitly states that the two trolleys can operate independently or together.

How should capacity be specified for tandem lifting?

Provide both the total load and the maximum load expected on each trolley, including rigging and any lifting beam.

What information is needed for synchronized lifting?

Provide lifting-point spacing, center of gravity, allowable tilt and the required synchronization tolerance.

Does the source include VFD control?

The source states that bridge and trolley travel can use soft-start or variable-frequency speed control.
