Overview

The CIMC Chassis Trailer is a skeletal intermodal trailer designed to transport standardized shipping containers between ports, rail terminals, distribution facilities, warehouses, and customer locations.

One of the best-known CIMC configurations is the Revere 20-foot/40-foot City Combo chassis. Its adjustable frame allows one chassis to transport either a loaded 20-foot ISO container or a loaded 40-foot ISO container.

Unlike a flatbed trailer, a chassis does not have a conventional cargo deck. It uses structural frame rails, bolsters, and twist locks positioned to support and secure the container at its lower corner castings.

CIMC Intermodal Equipment changed its name to CIE Manufacturing in 2020 as the business expanded its North American manufacturing capabilities. Current successor products are marketed under the CIE Manufacturing name.

Key Characteristics

The CIMC chassis is designed around standardized intermodal container dimensions. A container can be lifted onto or removed from the chassis using a port crane, gantry crane, reach stacker, or container handler.

The Revere City Combo uses an extendable frame that changes length for 20-foot or 40-foot container operation. Locking pins secure the chassis in its selected position.

Twist locks engage the container’s corner castings and prevent it from separating from the chassis during transportation.

The open skeletal frame reduces empty weight compared with a conventional platform trailer. Because the container serves as the cargo enclosure, the chassis only needs to support, secure, and distribute its weight.

CIMC promoted advanced corrosion protection, robotic welding, laser metal cutting, premium components, radial tires, LED lighting, and ABS equipment on later Revere chassis.

Common Specifications

Container Compatibility

The Revere 20-foot/40-foot City Combo is designed to transport:

  • One loaded 20-foot ISO container
  • One loaded 40-foot ISO container
  • One loaded 40-foot high-cube container when properly configured

Other CIMC and successor chassis configurations were developed for 20-foot, 40-foot, 45-foot, and 53-foot containers.

Frame Construction

The chassis uses high-strength steel main rails, crossmembers, front and rear bolsters, and an upper coupler assembly.

A combo chassis includes telescoping or sliding frame sections that allow its overall length to change.

Width

A nominal width of approximately 96 inches is common for North American container chassis.

The container itself is typically approximately eight feet wide.

Chassis Length

A 20-foot/40-foot city combo chassis operates in two primary positions.

The shorter position supports a 20-foot container.

The extended position supports a 40-foot container.

Exact retracted and extended dimensions vary according to the chassis model.

Axles

A tandem-axle arrangement is common on city-combo chassis.

Tri-axle configurations are available for dense containers and operations requiring additional weight distribution.

Suspension

The Revere City Combo commonly uses a mechanical spring suspension.

Later premium configurations used Hutchens mechanical suspension components.

Air-ride suspension may be available on selected chassis types.

Brakes and ABS

Commercial air brakes and an antilock braking system are commonly installed.

Later Revere specifications included premium brake chambers, slack adjusters, air valves, and electronic ABS controls.

Wheels and Tires

Radial commercial trailer tires are standard on later configurations.

Steel wheels are common, with aluminum wheels available on certain lightweight or premium chassis.

Landing Gear

Two-speed landing gear supports the chassis when it is disconnected from the tractor.

Later Revere specifications included premium intermodal landing gear designed for repeated port and rail-yard use.

Twist Locks

Container twist locks are positioned at the chassis bolsters.

Available styles include:

  • Fixed twist locks
  • Retractable twist locks
  • Flip-up twist locks
  • Drop-in twist locks

Twist locks must fully engage the container’s corner castings before transportation.

Sliding and Locking System

A combo chassis uses a telescoping frame with mechanical or air-assisted locking pins.

The driver must confirm that all frame-locking pins have fully engaged before moving the container.

Electrical System

A modular electrical harness supports:

  • LED marker lights
  • Tail lights
  • Brake lights
  • Turn signals
  • ABS equipment
  • Identification lights
  • Optional telematics

Corrosion Protection

Later CIMC chassis used a cathodic electrocoating or KTL coating process designed to protect steel surfaces against corrosion.

Road salt, port environments, standing water, and coastal air still make regular corrosion inspection necessary.

Specifications differ across production years and configurations. Current successor products and technical information are available through CIE Manufacturing.

Limitations or Considerations

  • Cannot transport conventional freight without a container
  • Container weight may exceed legal axle limits
  • 20-foot containers can contain extremely dense cargo
  • Extendable frames require additional inspection
  • Locking pins can become difficult to operate when corroded or damaged
  • Twist-lock failure can create a serious cargo-separation hazard
  • Chassis used in shared pools may receive inconsistent maintenance
  • Port and rail environments accelerate corrosion and component wear
  • Bare chassis can be difficult to see when backing
  • Tire, brake, and lighting defects are common concerns in high-use drayage operations
  • Drivers may need to inspect several chassis before finding a roadworthy unit
  • Container position can significantly affect kingpin and axle weights

Driver and Operator Considerations

The driver should verify that the chassis is set to the correct length before a container is placed on it.

All twist locks must be fully engaged and secured. The driver should walk around the container and inspect every connection point before leaving the terminal.

Extendable chassis locking pins should be checked visually. Air-assisted systems must release and re-engage correctly.

Container identification numbers, seals, shipping documents, placards, and gross weight information should be confirmed before departure.

Drivers should pay particular attention to tires, brakes, lights, mudflaps, frame damage, and conspicuity markings because intermodal chassis often experience frequent drop-and-hook cycles.

Maintenance and Ownership Notes

The frame rails, bolsters, crossmembers, slider sections, locking pins, and twist locks should be inspected for cracks, corrosion, bending, impact damage, and wear.

Telescoping frame surfaces should remain clean and properly lubricated according to the manufacturer’s procedures.

Twist locks should move freely and fully engage the container corner castings.

Landing gear requires inspection of the gearbox, crank handle, legs, shoes, cross-shaft, and mounting brackets.

Suspension components, axles, brakes, ABS equipment, tires, wheels, lights, and the chassis electrical system require routine preventive maintenance.

Corrosion should receive immediate attention, especially around bolsters, suspension mounts, crossmembers, locking-pin holes, and electrical grounding points.

Buying Considerations

  • Identify the exact CIMC or CIE model
  • Confirm the supported container sizes
  • Determine whether the chassis is fixed or extendable
  • Verify the retracted and extended lengths

Comparison to Similar Trailers

Compared with a fixed 20-foot chassis, the CIMC City Combo can also extend to transport a 40-foot container. The combo design adds versatility but also introduces slider components and locking pins that require maintenance.

Compared with a fixed 40-foot chassis, the shorter 20-foot position can improve maneuverability when transporting a single 20-foot container.

Compared with a tri-axle chassis, the tandem City Combo is generally lighter and easier to maneuver. A tri-axle chassis may provide better weight distribution for dense cargo.

Compared with a conventional flatbed trailer, the CIMC chassis provides faster container transfer and standardized twist-lock securement. A flatbed can transport a wider variety of non-containerized freight.

Compared with a specialty trailer, the chassis is focused specifically on port, rail, and container operations.

Regulatory and Compliance Notes

The CIMC Chassis Trailer must comply with federal, state, provincial, port, rail, and intermodal requirements governing trailer dimensions, axle weights, brakes, ABS equipment, tires, lighting, container securement, and inspections.

Intermodal equipment providers are responsible for systematic inspection, repair, and maintenance programs for chassis offered to motor carriers.

Drivers must complete an appropriate pre-trip inspection and report defects found on intermodal equipment.

Container gross weight does not determine whether the combination is legal. Operators must account for chassis tare weight, tractor weight, axle spacing, cargo distribution, bridge laws, and individual axle limits.

Hazardous materials transported inside a container require appropriate shipping papers, placards, emergency information, and driver qualifications.

Real World Operating Notes

CIMC chassis are commonly used in repeated drop-and-hook operations where the trailer may be shared among several drivers and carriers.

The chassis condition can vary considerably in a shared pool. Drivers should not assume that another operator or facility has completed the required inspection.

Twenty-foot containers frequently carry dense commodities. A container that is not filled by volume can still exceed legal axle or gross-weight limits.

City-combo chassis improve fleet flexibility, but the sliding system must remain clean and operational. Corrosion, debris, bent locking pins, and frame misalignment can make adjustment difficult.
