Engineering


Carpenter Crane Hoist has years of experience in the lifting industry. This experience gives CCH the ability to solve some very unique lifting problems. Our experience has given us a diverse library of knowledge for solving problems. CCH can design it, engineer it, fabricate it and test it to ensure a workable solution that is functional and cost effective.

CCH can use this experience to design cranes for restricted head room as well as for clean applications looking at specific molecular contamination. CCH can design standard crane as well as cranes for very corrosive environments.

With CCH’s unique background we have developed a line of clean rooms that use our crane support structure to support the clean room. This makes a very cost effective and functional clean room.


Design

CCH uses Solid Works 3-D modeling and analysis program for all its design work. Our Mechanical engineer is a certified Solid Works Professional

CCH currently is using the latest in 3D printing for rapid prototyping as well as production for parts. This gives CCH the ability to produce a part to verify the fit and function.

Engineering

CCH has in-house mechanical engineering for most projects and uses a third party structural PE when required for the project


Fabrication

Carpenter Crane Hoist manufac¬turing facility is located at Mare Island Shipyard in Vallejo, CA. There is a 100,000 sq ft facility with 10-ton and 15-ton crane btays 35 feet tall. CCH has MIG and TIG welding capability for steel, stainless steel and aluminum


NASA’s James Webb Telescope project

The James Webb telescope project was a project that moved CCH into a cleanliness and design that had never been done before. The application was for a 25 ton low headroom crane. The crane was to lift the telescope so it could be moved into the environmental chamber. The crane was to operate over mirrors that are sensitive to specific out gassing. The head room was very tight and required a unique design to meet the lift requirement. CCH worked with Midwest Cleanrooms, Northrup Grummon and Goddard Space center to develop the clean technology to meet the stringent requirements of the lift.


KLA/Tencor

Optics Service Kit

The customer needed a way to lift a very sensitive optics module. The module was sensitive to specific molecular contamination. The module needed very precise lifting speed control. In order to achieve the control they needed CCH designed a control package to fit the application. The hoist will lift extremely slow and is not load sensitive. Along with the hoist and rails for it to operate on was a cart to store all the components for easy install and removal.


Samsung Semiconductor

Equipment Service Crane Patent Pending

The customer need a lifting solution to service the process chambers on the wafer processing equipment. We worked closely with Samsung’s personnel to design a crane that would reduce injuries and shorten down time for servicing.
The crane is operated by remote control and has a float mode. In the float mode the crane senses the lifted load and allows the operator to move the load up and down without the use of controls giving the operator freedom of movement to align and install the components.

Along with the crane we designed the lifting fixtures for the servicing and a cart to store the fixtures on when not in use.


CSL Plating

The corrosive environment in a plating shop is a major problem for steel structures. The common way to deal with it is to use stainless steel. CCH has a proprietary process we use for corrosive applications. The process uses a fusion bonded polymer. This allows us to use steel structures and product in a very corrosive environment. There is a substantial cost savings for the customer. This application had fume hoods and duct work to work around. The solution was an articulated arm mounted on two monorails. This gave them the freedom of movement and the ability to reach around the duct work.
