Rigid Light Cranes

Rigid track structures are truss-type. Three basic track cross-sections can be combined to create a variety of truss configurations. These can be tailored to accommodate varying loads and spans by adjusting factors such as the size of the top chord, web members, and bottom chord (track). The truss structure's high load capacity, large span, excellent stability, and attractive appearance have made rigid track cranes increasingly popular in the light and small lifting industry.

The following are several common structural options:

RIGID CRANE COMPONENTS

RHT02/05/10/20 Main Beam Trolley
█The main beam trolley is used for hanging lifting mechanisms, etc. Its wheels are made of high-strength nylon and have a corresponding slope, allowing them to conform to the rail tread, ensuring smooth operation and automatic centering. Bent wings at both ends prevent the trolley from accidentally falling off the track, ensuring full safety.

RET02/02L/05/05L/10/10L/20L Single-Girder Rail Trolley
■Connects the rail to the main beam. This rigid connection ensures the main beam remains perpendicular to the rail during movement, allowing both sides of the beam to move synchronously without twisting.

RET60D/75D/90D Double-Girder Rail Trolley
In double-girder construction, the end beam trolley is integrated to ensure consistent spacing between the two beams.

Track Hanger
■Used to securely connect the top chord and crossbeam of a truss. The size and thickness of the track connector's clamping plate vary depending on the load.

Track Connectors
The three track connector models for the 60, 75, and 90 series are:
RRC02/05/10
[Connectors between two adjacent fixed rails. Adjust the screws above to ensure a smooth connection between the two fixed rails, allowing the trolley to pass smoothly.]

Track End Caps
The three track end cap models for the 60, 75, and 90 series are:
REC02/05/10
■ Track end caps are used to prevent dust and foreign matter from entering and enhance the appearance.

Cable Pulley
Used to suspend and tow cables while the main beam or hoist is traveling.
RCTO1 Cable Pulley
RCE01 Cable Terminal Clamp

External Stops
■Compatible with 60, 75, and 90 track sizes, Model: RAS01
■Adjustable stop positions based on the track's operating area.

RHT02D/05D/10D/20D Double-Girder Trolley Frame
■Default double-girder center spacing is 700mm (special dimensions available upon request).
The double-girder trolley frame evenly distributes the hoist load across the two main beams.

Secondary Protection
To prevent unexpected situations, secondary protection devices are installed on each fixed rail, each main beam, and each hoist. They are categorized as follows:

Electric trolley
When the travel mode is electric, the main beam and hoist drive unit.
The motor can be selected from domestic or imported brands.
[Default travel speed: 5-20m/min (variable frequency dual speed)]

Electrical Control Box
■Control unit for driving the vehicle. Depending on customer requirements, the selected configuration may vary.
The default control configuration is variable frequency.

CUSTOMER INPUT

·Load w
The load of a single main beam, the load of the entire frame

·Rail Length L
Refers to the length of the fixed rails on both sides.

·Girder Span S
Refers to the center-to-center distance between the two fixed rails. The default is 250mm.

·Beam Height H
The height of the main beam trolley's hoist (for free-standing structures, usually calculated from the ground or column support point).

·Hook Coverage
Due to its size, the equipment has certain blind spots. Users must consider the actual hook coverage requirements. Furthermore, a safe clearance must be reserved for equipment installation and operation, which may vary slightly from the space dimensions.

·Structural Type and Operation Control Method
Structural type refers to free-standing (foundation thickness) or suspended type. Main beams can be single, double, or telescopic, and the required number and load are also included. Operation methods include manual, fully electric, or electric operation of the trolley and trolley. Power supply methods include flat cable, busbar, or C-rail. Control methods include handle control and remote control.
